How Does the Marvel Rivals Random Option Work?

Is there a random hero button on the select screen?

Not according to any source we can check. The wiki's game mode pages describe how Quick Match, Competitive, Practice vs. AI and Custom Game work, and none of them mentions a random-pick button in hero select. The patch notes from launch to October 2026 contain no entry adding, changing or fixing one, which is unusual for a feature players would use every day: the notes record far smaller changes, such as the controller hold time to switch heroes dropping from 1 second to 0.5 seconds in August 2025.

That doesn't prove no such option exists. The wiki has gaps, and hero select menus aren't always written up. It does mean we can't tell you how one works, and pages that describe a "dice button" in detail, including an earlier version of this page, are asserting something no source supports. Because of that, the rest of this page sticks to random features that are documented.

One related rule is documented: what happens to your choice of hero in Competitive. Bans apply when every player in the lobby is Gold III or higher, and since Season 10.5 each team bans three heroes in turns. Whatever method you use to pick a hero at random, a banned hero is off the table, so check the bans before you commit to the result.

The Random duel type in the Clobberin' Club

The clearest documented random option is in the Clobberin' Club, an underground duel hub in Times Square run by The Thing. The wiki explains how to start a duel: walk up to another player, press Interact, choose battle, pick a Private or Public duel and click Initiate. Before sending the request you can change the Duel Type from Classic to Random, in which "heroes change after each round", or to Unique, where you choose a limited pool of heroes before the fight. A duel lasts one minute, and the first player to three points wins. A Public duel is shown on the big screen in Times Square and costs 100 Units.

The April 17, 2026 update added two rules. Mirror Type, for Random duels only, has three settings: Full Mirror, Role Mirror and No Mirror. The patch note doesn't define them. The names suggest that Full Mirror gives both players the same hero and Role Mirror the same role, but that is our reading, not the source's. Assign Selectable Roles, for all duel modes, lets you customise the list of available heroes by role type. The same patch let you send duel invitations from the Times Square chat channel and start private duels while matchmaking (the duel ends when a match is found).

This is the closest thing the game has to a documented random-hero mode, and it is a good way to practise heroes you'd never pick yourself.

Other places the game randomizes for you

Several other modes and systems use randomness, each documented on the wiki.

Clone Rumble. First added on March 7, 2025, it is a mode in which "you and your teammates choose from the same heroes". When it returned as a permanent Arcade mode on September 12, 2025, the rules became: choose from two heroes randomly selected by the system, with the first side to 100% capture progress on the map winning. A September 17, 2026 fix mentions players "randomized as Deadpool" in Clone Rumble, so Deadpool is among the heroes it can offer. Availability rotates, though: when we read the wiki's Arcade Modes page on October 21, 2026 it listed Clone Rumble as currently unavailable, so check the Arcade menu before planning around it.

Ultron's Battle Matrix Protocol. An experimental mode that ran June 6 to 23, 2025. Each player picked six heroes from a randomly assigned pool of 6 Vanguards, 6 Duelists and 6 Strategists, then played rounds until one player remained.

Costume Rotation. Added September 12, 2025: your hero's look is randomized from several unlocked costumes you select.

Custom Game bots. The wiki's Custom Game page says the host can add bots of any difficulty to either team and have them pick any hero or a specific hero. It doesn't describe how an "any hero" bot chooses, so we can't say whether that pick is random, but it is the one documented setting that hands hero choice to the game.

Maps, modes and backgrounds. Quick Match shuffles randomly between Domination, Convoy and Convergence; Arcade's Free Fight and Clone Rumble pick a map at random when the match is found; and since November 14, 2025 the home screen background can be set to rotate randomly.

None of these chooses your hero in an ordinary Quick Match or Competitive game. For that, a separate tool is the documented option.

How our randomizer picks a hero (from its source code)

Our tool is at marvel rivals hero randomizer, and because we wrote it, we can describe exactly what it does. It draws from the roster in the site's hero list: 55 heroes in Season 11, made up of 14 Vanguards, 27 Duelists, 13 Strategists and Deadpool, who is listed as multi-role.

Role filters. You choose which roles to include. Deadpool stays in the pool whenever any role is on, because he can play all three. You can't switch every role off; the last one stays on.

Bans. You can ban any hero, and banned heroes are never rolled. Use this for heroes your team has banned in Competitive or heroes you don't want to play.

No-repeat. On by default in single-hero mode. The tool remembers your last 40 rolls and skips heroes you've rolled recently, but never so many that the pool would be empty: it always leaves at least one hero available. Within what remains, every hero is equally likely: the pick uses your browser's standard random number generator to choose one entry from the filtered list, with no weighting by tier, popularity or anything else. That also means the tool has no idea what your team or the enemy is playing, so team needs are yours to set through the filters.

Team mode. At marvel rivals team randomizer you pick a team size of 3, 4, 5 or 6. With Role-balanced on, the tool aims for two Vanguards, two Strategists and two Duelists, filling Vanguard first, then Strategist, then Duelist, and fills any remaining slots from what's left. You can lock heroes you like and reroll only the others; locked heroes count towards the role targets.

Everything else. The space bar rolls. Your filters, bans, no-repeat and team settings are saved in your browser on your device, and nothing touches the game, your account or your files. There's also a generator at random marvel rivals character generator that rolls 1, 2, 3 or 5 heroes at once.

Using a random pick in a real match

A random pick works best when it fits the match rules. In Competitive, check the bans first, then ban those heroes in the randomizer so you can't roll them. With the turn-based bans from Season 10.5, that's six heroes in total. If your team needs a role, set the role filter before the hero select timer starts so you only have to press once.

Outside Competitive, check the mode's rules. Free Fight, an Arcade mode, lets each team ban two heroes under the Competitive ban rules but places no restrictions on duplicate heroes, which makes it a good fit for a group in which everyone plays whatever they roll, even the same hero. For a group challenge with fixed rules, see random hero only challenge marvel rivals. For practising a hero you'd never choose, a Random duel in the Clobberin' Club gives you a new hero every round in a friendly one-on-one setting, away from Competitive.

Finally, a word on streaks. Real random picks repeat and cluster, which is why the same hero can appear twice in a row even when every hero is equally likely. Our no-repeat setting exists to stop that in single-hero mode. If you want to know which heroes the roll can land on, the full list with roles is at marvel rivals characters list.
