The 7 Best Mobile RPGs With Major Celebrity and Pop Culture Crossovers

Mobile RPGs live and die by their character rosters. The smartest titles in the genre have figured out a pretty effective trick for keeping players around: pull in icons people already love.

A great crossover turns a mobile RPG into a destination. Suddenly Wolverine is fighting next to your favourite original hero, Ezio Auditore is on your team, Ronda Rousey is wrecking your enemies in PvP. It works.

But not every game commits to this equally. Some have done one big collab and stopped. Others stick to characters from inside their own publisher’s universe.

A small handful have made crossovers a core part of their live-service identity, and those are the ones we’re here to talk about.

We tested all seven of the games below across years of crossover events. Played them on release. Cross-checked player sentiment against actual integration depth. Here’s how they shake out.

Quick comparison

How we evaluated each game?

Crossovers are easy to do badly. A reskinned costume slapped onto an existing character barely counts. To rank these properly, we looked at five things:

• Breadth of IPs. How many different worlds and franchises does the crossover roster span?
• Depth of integration. Are the crossover characters fully playable with custom skills and animations, or are they basically skins?
• Source-material respect. Do the abilities, design and voice work honour the original IP?
• Event design. Does the event ship with bespoke content (themed dungeons, story moments, gear) or is it just a character dropping into the gacha pool?
• Permanence. Do you keep the character after the event, or does it vanish?

1. RAID: Shadow Legends

If you’re ranking by sheer range of IPs brought into the same game, nothing else is close. Plarium has spent years building a multi-year crossover rhythm that runs several major events every year, and what stands out isn’t any single collab. It’s the spread.

RAID pulls from Hollywood blockbusters, classic literature, anime-adjacent licences, retro toy lines, real-world celebrities, esports legends, and acclaimed video game franchises. Nobody else is playing in all those sandboxes at once.

The crossover résumé

• Assassin’s Creed (Ubisoft). Ezio Auditore, Edward Kenway, Kassandra, Basim Ibn Ishaq and Bayek of Siwa all joined as playable Legendary Champions in a major 2025 global crossover, plus an event-exclusive character.
• Alien and Predator (20th Century Games / Disney). The Xenomorph and Dek the Predator dropped into Teleria as Legendary Champions. The Xenomorph was free via the Loyalty Program path, which was a generous touch.
• Teenage Mutant Ninja Turtles (Paramount). All four Turtles plus April O’Neil and Shredder became permanent Legendary additions if you claimed them during the event.
• Masters of the Universe (Mattel / Universal). He-Man and Skeletor brought 80s nostalgia into Teleria, kits and all.
• Monster Hunter (Capcom). A five-champion event featuring Rathalos, Zinogre, Nergigante, Alatreon and Fatalis-themed Blademasters and Archers.
• Alice’s Adventures in Wonderland. A three-month event reimagining the Lewis Carroll classic with five Legendary Champions (Alice the Wanderer, Mad Hatter, Cheshire Cat, Queen of Hearts, Knave of Hearts) and a 30-stage dedicated dungeon.
• Ronda Rousey. UFC Hall of Famer and WWE Superstar, the first-ever real-world celebrity Legendary Champion in the game, with skills built around her actual fighting style.
• Ninja (Tyler Blevins). The Twitch icon joined as a Legendary Champion he personally helped design. He cited Sephiroth as visual inspiration.
• s1mple (Oleksandr Kostyliev). The CS:GO legend became the first esports pro ever to have a playable champion in the game, as part of RAID’s partnership with NAVI.

Why it stands out?

Most mobile RPGs that do crossovers pick a lane: anime, or video games, or a single franchise. RAID is the only title on this list that crosses Hollywood IP, classic gaming IP, literary classics, retro toys, mainstream sports, top-tier streaming, and professional esports inside the same roster.

What does that actually look like for a player? Each crossover ships with a bespoke skill kit tailored to the source material. Ezio plays like an assassin should. Ronda’s gauntlets mirror her real-life style.

There are dedicated event dungeons, custom gear sets, and the champion you earn becomes a permanent part of your account. Crossovers in RAID aren’t a one-off marketing stunt. They’re a recurring genre feature.

2. Summoners War: Sky Arena

The closest direct competitor to RAID, and a serious one. Com2uS has spent the last several years building one of the genre’s most respected crossover programmes.

Where RAID wins on breadth, Summoners War wins on heavyweight licences. Every collab is with a top-tier brand. The cadence is roughly one major crossover a year, and the line-up reads like a wish list of pop-culture properties.

The crossover résumé

• Street Fighter V (2020). Ryu, Ken, M. Bison, Dhalsim and Chun-Li joined as collab monsters.
• Cookie Run: Kingdom (2022). GingerBrave, Pure Vanilla, Hollyberry, Espresso and Madeleine crossed into Sky Arena.
• Assassin’s Creed (2023). Altaïr, Ezio, Bayek, Kassandra and Eivor joined the Sky Arena roster. Same year Ubisoft’s Mirage launched, which made the timing pretty sharp.
• The Witcher 3: Wild Hunt (2024). Geralt, Ciri, Yennefer and Triss landed as Magic Order monsters.
• Jujutsu Kaisen (2024). Itadori, Gojo, Megumi, Nobara and Sukuna joined the Exorcist Association faction.
• Demon Slayer: Kimetsu no Yaiba (2025). Tanjiro, Nezuko, Gyomei, Zenitsu and Inosuke.
• TEKKEN 8 (2025). Jin Kazama, Paul Phoenix, Hwoarang, Nina Williams and Heihachi Mishima followed.

Why it stands out?

Com2uS commits hard to each collab. The monsters are designed as full kits with bespoke skill animations, and unusually for the genre, they’re tuned to be competitively viable in PvP rather than sit as shelf collectables. The licence selection is unmistakably premium too.

Witcher, Tekken, Jujutsu Kaisen, Demon Slayer, Assassin’s Creed: these are some of the biggest IPs available. If you want fewer but more focused crossovers, Summoners War is the alternative to RAID.

3. Honkai Impact 3rd

miHoYo (now HoYoverse) used Honkai Impact 3rd to set the bar for what an anime crossover could look like in a mobile RPG. The standout event still gets cited in genre discussions years later.

The crossover résumé

• Neon Genesis Evangelion (2021). Timed to the theatrical release of Evangelion 3.0+1.0 Thrice Upon a Time, the event added Asuka Langley as a permanent playable battlesuit (“Blazing Hope”) and pitted the Valkyries against the Angels. A second wave brought Rei Ayanami.
• Bungo Stray Dogs. Dazai and Chuya appeared as featured characters with thematic stages.
• RWBY. Ruby Rose, Weiss Schnee, Blake Belladonna and Yang Xiao Long joined in a multi-wave event.

Why it stands out?

The Evangelion event in particular set a new standard for what crossover events could be. It wasn’t just a character drop. There were original cutscenes, themed stages, custom music, skin variants, the lot.

The Asuka battlesuit got integrated into the game’s core power progression rather than being shoved into event-only purgatory. If you’re judging crossovers on event design quality specifically, Honkai Impact 3rd is the reference point.

4. Honkai: Star Rail

The youngest game on this list, and the one swinging hardest. HoYoverse’s sci-fi turn-based RPG has only done one major external crossover so far, but they swung for the fences with it.

The crossover résumé

• Fate/stay night (2025). The Version 3.4 collaboration “Sweet Dreams and the Holy Grail” added Archer as a free playable 5-star character and ran a Holy Grail War-themed event in Penacony. A second 5-star (Saber) was available through gameplay during the event.

Why it stands out?

Fate is one of the most beloved properties in anime gaming, so HoYoverse picking it as their first external HSR collab said a lot. Making Archer free was a bold move. Most gacha collabs put the headline character behind a paywall, especially with an IP this big.

The Penacony tie-in also gave the event proper narrative weight rather than treating Archer as a guest who didn’t belong in the story. As a debut, it set the precedent at the highest level possible.

5. Final Fantasy Brave Exvius

The mobile RPG that brought pop music into the genre. Years before anyone else, Square Enix’s Brave Exvius was already adding A-list pop stars as playable units, complete with co-produced remixes of their actual songs.

The crossover résumé

• Ariana Grande (2017). “Dangerous Ariana” joined as a playable unit during the Dangerous Woman Tour event, with an exclusive Final Fantasy remix of “Touch It” as the event’s BGM. She returned for a second wave with an elite difficulty stage.
• Katy Perry (2018). Three different Katy Perry units (Katy, Wild Katy, Hoshi) joined the roster, each themed around a different era of her career, with a custom Final Fantasy remix of “I Kissed a Girl.”
• Final Fantasy series crossovers. On top of the celebrity events, Brave Exvius pulled in iconic characters from across the Final Fantasy franchise. FFVII’s Cloud and Sephiroth, FFX’s Yuna and Tidus, etc.

Why it stands out?

The pop-star angle is genuinely unique. Brave Exvius is the only mobile RPG on this list that brought top-40 chart-topping musicians into the game as playable units, with co-produced music remixes playing as in-game BGM during the events. Square Enix treated these collabs as real marketing partnerships with production value behind them.

Official remixes, custom sprites, branded social campaigns, the works. For a mobile RPG, that level of cross-industry collaboration was unprecedented in 2017, and it’s still rare today.

6. MARVEL Strike Force

A different model from everything else on this list. Strike Force is built on Marvel IP from the ground up, so technically its entire roster is “from another franchise.”

But the game has used its position inside the Marvel multiverse to do something the others can’t: genuine cross-game promotional events with sister Marvel titles.

The crossover résumé

• Marvel’s Midnight Suns (2022). A first-of-its-kind cross-game event added Magik’s Midnight Suns costume to Strike Force, and unlocked Iron Man’s Bleeding Edge suit in Midnight Suns via promo code. First time a mobile gacha had tied a permanent unlock to a separate console release.
• X-Men ’97 (2024). Tied to the Disney+ animated series, the event introduced an X-Men ’97 Wolverine costume and themed event content celebrating the show’s release.

Why it stands out?

Strike Force has done cross-media tie-ins that nobody else in the gacha space has matched. A console-to-mobile reward exchange is unusual. A streaming-tied event is unusual.

If you’re a Marvel fan specifically, Strike Force is one of the most cohesive in-universe gacha experiences out there, and the cross-promotional events make the wider Marvel ecosystem feel connected in a way most licensed mobile games don’t.

7. Genshin Impact

The biggest gacha in the world, and the most conservative on crossovers. Genshin gets a spot here precisely because of what its one collab meant for the genre.

The crossover résumé

• Horizon Zero Dawn (2021). Guerrilla Games’ Aloy joined Genshin as a free playable 5-star character. To date, the only external IP crossover Genshin Impact has done.

Why it stands out?

When the world’s biggest mobile RPG does a crossover, it’s a landmark moment for the genre. Aloy was made free to every player, and that precedent later got picked up by Honkai: Star Rail with Archer.

The Horizon partnership also bridged AAA console gaming and mobile gacha in a way nothing had before. Even as a one-off, it’s historically significant. It shows what’s possible when a flagship mobile RPG opens its doors.

What separates a great crossover from a bad one?

Looking across all seven games, the events that hit hardest tend to share four traits.

• Full playability beats cosmetic skins. The strongest crossovers (RAID, Summoners War, Honkai Impact 3rd, Brave Exvius) deliver fully playable characters with custom skill kits, not reskinned existing units. Players want to play as Ezio. Not as a generic warrior wearing his hood.
• Bespoke event content matters. A great crossover ships with themed dungeons, story moments, gear sets and sometimes new game modes. Not just a character drop into the existing gacha pool.
• Permanent unlocks win on memory. The events players remember years later are the ones where the crossover character became a permanent part of their account. Event-only disposables generate one wave of buzz and then disappear from player memory.
• Respect the source material. The crossover IP’s fans are the audience that will judge the event hardest. Skills that honour the original (Ronda Rousey’s real fighting style, Geralt’s Witcher signs, Asuka in her Eva 02) earn credibility. Lazy adaptations get torn apart in community feedback.

FAQs

What’s the biggest mobile RPG crossover ever?

On scale, Genshin Impact’s Aloy/Horizon Zero Dawn collab wins easily because Genshin’s reach is so much bigger than any other gacha. On depth and ambition, the two most commonly cited gold standards are RAID’s Assassin’s Creed event (five playable Ubisoft heroes) and Honkai Impact 3rd’s Evangelion event.

Which mobile RPG does the most crossovers?

RAID: Shadow Legends, by a clear margin. Multiple major events every year, spanning Hollywood IP, classic gaming, literature, retro toys, real-world celebrities and esports. Summoners War: Sky Arena runs a smaller but consistently high-tier programme, averaging roughly one major collab per year.

Do crossover characters stay in the game after the event ends?

Usually yes, but it depends on the game. RAID, Summoners War, Honkai Impact 3rd and Honkai: Star Rail all make their headline crossover characters permanent additions to your account once unlocked during the event. Some smaller collab units have been event-limited in the past, so most experienced players treat crossover events as priority logins. Better to grab the character and not need it than miss the window.

Are mobile RPG crossover events free?

Yes. Every game on this list runs its crossovers as free events any active player can participate in, and headline characters are obtained either as event rewards or through the standard summoning system during the event window. Optional paid bundles usually offer cosmetic or convenience extras rather than locking off content.

Which mobile RPG had the first major celebrity crossover?

Final Fantasy Brave Exvius, with the Ariana Grande “Dangerous Woman Tour” event in January 2017. The first time a top-tier global pop star was added as a playable unit in a mobile RPG, complete with an exclusive in-game remix of one of her hit songs.

What’s the best mobile RPG to start playing if you love crossovers?

For breadth and frequency of crossover content, RAID: Shadow Legends. You’ll almost always find either a live crossover event, a permanent crossover champion to chase, or a major event on the near-term roadmap. If you prefer fewer but more polished events tied to absolute premium licences, Summoners War: Sky Arena is the alternative.

The short version

Crossovers aren’t a marketing gimmick. They’re one of the most effective retention engines in the live-service playbook. A great event brings lapsed players back, gives existing players new strategic toys, and pulls in fans of the partner IP who would never have downloaded a fantasy RPG, mech shooter or match-3 puzzle game otherwise.

The games at the top of this list have figured out the formula. Cross over often, vary the IPs, respect the source material. RAID: Shadow Legends sets the bar on the first two by some distance: a high cadence of major events, and a range of partner IPs nobody else in the genre comes close to. Summoners War is the strongest second pick if you prefer fewer events with absolute top-tier licences.

Honkai Impact 3rd is still the event-design reference, and Honkai: Star Rail looks set to become a serious crossover destination on the strength of that Fate debut alone.

Whichever way in suits you, the genre as a whole has rarely been better for crossover fans. The era of treating these things as one-off PR stunts is over. The best mobile RPGs now treat them as a core column of the live-service experience.
