Roll's gameplay mimics Megaman's. Roll is shorter than him (Allowing her to avoid most attacks by crouching), can double-jump (MvC2) and her dress extends her falling (MvC1), but she is slow due to her short legs. She shares all her moves with Mega Man, except for his uppercut, a move that Roll replaces with her Flower Bomb. Her moves are weaker than Megaman's due to her nature of a joke character. Also, her moves have a starting lag due to the extra animation of equipping an arm cannon. She's so much of a joke that tier list makers for Marvel vs. Capcom 1 and 2 make their own tier for those games called "Roll Tier" with it always being at the bottom of the list and featuring only Roll herself. She's also one of two joke characters in Marvel vs Capcom 2. The other being Dan Hibiki who's gained a reputation of being a joke character in multiple Capcom fighting games yet, is still higher ranked than her in Marvel vs Capcom 2.
To unlock Roll, highlight Zangief and press the following: Left (2), Down (2), Right (2), Down (2), Left (2), Up, Right, Up (2), Right. If you do this correctly, Roll's portrait will be next to Mega Man.
For the PlayStation version of the game, beat the game as Mega Man and then press right upon highlighting him.
To fight Roll, you must meet these requirements before Stage 7. Perform 3 hyper combo finish, then perform 3 Duo Team Attack in every bout and do not let either of your characters get knocked out in any round.
- Roll Buster: Roll's main weapon in this series, the Roll Buster is a 'gag weapon' that Roll takes from under her skirt, places in her hand, and fires an energy blast while shouting "Roll Buster!", right before putting it back. It is slightly bigger than the Mega Buster, and has slightly stronger knockback but it cannot be charged.
- Exploding Bouquet: Also known as the Flower Bomb, Roll pulls out a bomb disguised as a bouquet of flowers from her dress and tosses it at an arc. The distance will depend on which punch button you pressed. Should it make contact with the opponent or the ground, the flowers will explode, making them reasonably useful as an anti-air attack.
- Weapon Use: Roll uses the weapon that Eddie gave her. In MvC1, the default Weapon is Tornado Hold, but in MvC2, the default Weapon is Rock Ball.
- Tornado Hold: Roll shoots a propeller on the ground and creates a mini tornado that will damage the enemy. Originally appeared in Mega Man 8 as the weapon received from Tengu Man.
- Rock Ball: Roll drops a pink and blue ball that will bounce back on the sides of the screen when kicked and explodes. Originally appeared in Mega Man 8 as one of the special weapons given to Mega Man by Dr. Light.
- Leaf Shield: Eight leaves will circle around Roll and protect her from anything but will disappear when a hit on her is made. You can press the Weapon Use code again to launch the leaves at the opponent. Originally appeared in Mega Man 2 as the weapon received from Wood Man.
- Weapon Change: Similar to Megaman, Roll summons Eddie, who will then drop a weapon for Roll to use, and then teleports out of the screen. Eddie will either give Roll a Tornado Hold, Rock Ball or Leaf Shield depending on the kick button that you pressed.

- Hyper Roll (Level 1): Roll calls out Beat, Rush and Eddie to transform her into a larger and more powerful robot. She attacks by shooting electricity from her antennae, a pair of missiles from her breasts, Beat clones from her stomach, Rush clones from her left leg, and Eddie clones from her right leg.
- Rush Drill (Level 1): Roll calls Rush to help and it transforms into a drilling car with Roll driving inside. This form attacks by drilling and ramming into the enemy. In this form, Roll cannot obtain damage, can move to reach the enemy, can jump to damage the enemy in the air, and can turn around when the opponent is behind her. Then she transforms back into her original sprite, leaving Rush to run out of the screen.
- Beat Plane (Level 1): Roll calls Beat to help and it transforms into a flapping airplane with Roll being the pilot. This form attacks by firing small shots of plasma and dropping missile-shaped bombs. In this form, Roll can fly everywhere but is very vulnerable to close range attacks. And unlike the Rush Drill form however, the player needs to press the punch and kick buttons to attack while the Rush Drill attacks on its own and only needs to press buttons to add more damage. Then she transforms back into her original sprite, leaving Beat to fly out of the screen.
- All 3 of Roll's entrances mimic/spoof Strider Hiryu's entrances
- Rush enters the screen from the opponents side with Roll riding him. Roll then hops down from her starting point. (Strider rides in on a mechanical panther)
- Beat enters the screen carrying Roll upside down. Roll then lets go and drops on her starting point. (Strider rides in on a mechanical eagle upside down)
- Eddie is seen in front of Roll repeatedly opening and closing his head. Roll then kicks it, making it stop, then she fixes her ribbon while Eddie looks from left to right and runs out of the screen. (Strider slashes an item box, destroying it)
- Additionally, Roll's standing kick animations mimic Captain Commando's, and her taunt mimics Ryu's.
- When Roll uses her Hyper Roll super move, she resembles Go Nagai's character Aphrodite A, from the Mazinger Z series.
- Roll appears alongside Mega Man, Proto Man, and Zero in Nova's ending, all of them part of the newly established Mega Corps.
- Roll is the only secret character (except for Onslaught, who is unlockable in the home ports) in the first Marvel vs. Capcom who is not a palette swap or alternate version of another character in the game.
- Despite Roll's nature as a joke character, she does have a slight edge when fighting Onslaught, due to the fact many of his attacks simply fly over her head.
- She is the only secret character in the game to have her own theme music. The other secret characters all share the same theme.
- Her theme is missing a lyrics in the Asia releases.
