|Artwork of Roll from Mega Man 9|
DLN-002, Roll. is one of the first Robot Masters created by Dr. Light, created to be a housekeeper, lab assistant, and sister to Mega Man. She is one of the few known female characters in the original Mega Man series, and the only female humanoid robot until Splash Woman was introduced into the series.
Roll is primarily a melee character. Her main weapon is the Roll Swing which allows her to attack with a broom. The broom has a range of 2 and 2/3 tiles horizontally. She can also use other weapons similarly to other characters and has two utility weapons unique to her: the Tango Jump which allows her to call the pet cat Tango and jump on it to get to higher places similarly to Rush Coil and Proto Coil, and Flappy Beat which allows her to call the bird Beat and fly in the air by flapping his wings.
While the concept of her weapon comes from Mega Man Powered Up, Roll's broom attacks are inspired by Zero's gameplay with the melee Z-Saber in the Mega Man X and Mega Man Zero series. Roll can also chain a combo of three broom swings while on land, while she can perform a spin-attack with her broom if she attacks mid-air. If the Charge Broom setting is enabled for a level, the player can hold down the attack button to charge the broom, increasing its range and power.
Instead of sliding when the down and jump button input or slide button is pressed, Roll performs a roll. She can use the roll to go down 1 tile wide gaps. If the Dodge Roll setting is enabled for a level, Roll can also dodge attacks and become temporarily invulnerable to most attacks in this phase, although there is a slight cooldown period the player is required to wait between rolls. When this cooldown period is over, Roll will flash white and a chime sound effect will play.
- Roll's sprites are mainly inspired by her appearance in the 2008 Japanese mobile port of the first Rockman game with a few modifications to her design and pose.
- Roll is currently the only character to have a melee weapon as their default weapon.
