Marvel Rivals team-up synergies: best duos and trios by win rate

Marvel Rivals' team-up system rewards you for picking heroes that share narrative or mechanical ties. The catch is that "shares a team-up" doesn't automatically mean "wins together more." This post walks through what team-ups actually do, how Counterwatch's synergy data reflects them, and three high-confidence pairs currently winning more than any others in the community data.

What a team-up actually is

Marvel Rivals ships each season with a set of defined team-up pairings and trios. When the right heroes are on the same lineup, a bonus unlocks: usually a passive buff, a shared ability, or an ultimate modifier that makes the anchor hero noticeably stronger. NetEase publishes the current team-up roster each season and reshuffles it over time.

The important part for team composition: a team-up is a rule baked into the game, not a gentleman's agreement. You either have the partner on your team and the bonus is on, or you don't and it isn't. That is different from Overwatch, where every "synergy" is just heroes whose kits overlap well.

How team-ups show up in our synergy data

The community synergy win rates on a hero's page aggregate every tracked match where both heroes were on the same lineup, regardless of whether the team-up was officially "active" (all required partners present) or partially satisfied. That means you see the average of:

Matches where the team-up was fully unlocked and active.
Matches where only one partner was present and the team-up was inactive.

A synergy pair with a high win rate signals that the combination reliably wins when they share a team, without us claiming a direct causal connection to the team-up bonus itself. For the pairs below, the match counts are large enough that we can trust the edge is real.

Three high-confidence pairs from the current data

These are pulled from the current Marvel Rivals Standard mode, all ranks, all game types. Picked for sample size and role coverage.

Gambit + Rogue: 54.2% over ~16,400 matches

The highest-sample synergy pair in the current MR data. Both are X-Men, and they anchor one of the cleanest team-up interactions in the game. Gambit is a Strategist here, Rogue is a Vanguard: so the synergy plays as "frontline commitment plus a setup-heavy support" rather than two Duelists stacking damage. The sheer sample size (over 16,000 tracked matches) means this is one of the most confident synergy numbers on the site. If you are already planning to pick either, locking the partner is an easy win probability bump.

Spider-Man + Peni Parker: 55.4% over ~7,700 matches

Web-Warriors. Peni's trap-heavy defensive kit plus Spider-Man's web-mobility dive pattern cover each other almost perfectly: Peni locks down a position for the team to regroup into while Spider-Man can safely over-extend knowing there is crowd control waiting if the enemy team dives back. The ~7,700-match sample is large enough to trust, and the 55% edge is sizeable for a game where most synergies settle in the 52–54% range.

Hela + Namor: 55.2% over ~8,400 matches

A pure Duelist pair, so unusual territory: most high-synergy pairs in the data cross roles. Hela's ranged precision damage plus Namor's turret-anchored zone control means the enemy team has to commit to pushing through a corridor Hela already has a sightline on. The enemy's alternative is to flank, at which point Namor's turrets catch the flanker. The comp loses on open-sightline maps where Namor's turrets are easy to burst, but on the maps with distinct choke structure, this pair has been one of the quieter dominators of the current season.

Two ways to read the synergy list

Every hero detail page exposes two views on its strongest-duos card. The default is Top duos, which ranks pairings by absolute combined win rate — what the three numbers above are showing. That is the answer to "who is strong right now alongside this hero," and it bakes in both heroes' individual meta strength, which is usually exactly what you want when you are picking for the current patch.

The Best kit synergies toggle subtracts each hero's individual edge from the pair's win rate before ranking. If two 55% heroes show a 60% pair WR, that is exactly what each hero's individual edge predicted — zero kit synergy. A 62% pair from the same two heroes is a real +2pp lift over baseline, signal that something — kit interaction, team-up bonus, or both — is producing real lift independent of how strong each hero is alone. Numbers in this view are deltas (+X.Y% / −X.Y%) over expected, with the subtitle "Lift over expected when paired with X."

For team-up planning specifically, the kit-synergies view is the more honest read. Two strong meta heroes who happen to share a team-up will look like a great Top Duos pair regardless of whether the team-up bonus is actually doing the work. Best Kit Synergies pulls the individual-strength noise out of the picture, so a high residual means this pairing is winning more than the heroes' individual strengths predict. Use Top Duos to ask "who do I want on my team this patch?" Use Best Kit Synergies to ask "whose abilities actually combo with this hero independent of the meta?"

How team-ups change the counter read

The counters you see on a hero's page are averaged across team-up states. So if Hela has a 54% win rate into a specific enemy hero, that number is a blend of "Hela-with-team-up-active-matches" and "Hela-with-team-up-inactive-matches." Her actual edge with the team-up online is higher than 54%, and her edge without is lower.

Practical implication: if your team already has Hela's team-up partner on the roster, her real matchup edge is better than the aggregate suggests. That is worth considering when you are deciding whether a "soft counter" is worth swapping to: the team-up bonus can push a 52% aggregate into the 53–54% range.

The reverse applies if you are on the enemy side: a hero with a strong aggregate counter into your team becomes even more dangerous if their team-up is live. Watching which pairs the enemy locks tells you a lot about how their mid-match damage and sustain is going to scale.

Building a comp around team-ups

The strongest Marvel Rivals comps don't pick the "best five heroes in a vacuum." They pick around a team-up anchor and fill the remaining slots with heroes that cover the archetype gaps.

A workable process:

Pick the team-up pair you want to run. The three above are a solid starting point, but the best one tricks page also surfaces heroes whose win rate rewards mastery on their own.
Use the team builder to fill the remaining three slots. The builder scores each candidate across counter, synergy, and map performance against the enemy lineup, so you can see which fillers preserve your anchor's synergy and which break it.
Check the map before you lock. Team-up pairs that rely on zone control lose edge on maps with multiple flanks; team-ups that anchor mobility lose edge on narrow corridors.

The Counterwatch app runs the same scoring live during your match. When the enemy team picks a comp that neutralises your team-up (for example, a heavy burst Duelist picking apart your turret anchor), the overlay surfaces swap candidates as the picks happen.
