Character ability: battery. Everytime she hits the opponent or get hits she will power up a battery and when it's full it can be converted to extra blockbuster meter by tapping on the battery icon. Max to 3 levels, red for +10% bb1, blue for +10% bb2 and +20% bb1, green for +10% bb3 +20% bb2 and +30% bb1. Once used the battery will return to 0 charge, no matter if there was still some energy left. If battery is used more than twice a match se will be inflicted with overcharge (something like instant doom that will bypass final stand and immunity, no way to avoid it) and the rest of the team with something permanent like cripple and armor break. Or punish her teamates with something more extreme like 20 seconds doom and the enemy team with permanent heal block and permanent death mark. Since she's a robot she will be immune to bleed and heavy bleed but she also can't benefit of regen and heavy regen. Also can't get resurrected with Forbidden procedure but if she dies and still have a level 3 battery she will be back with full healt but special attack and blockbusters will permanently blocked for the rest of the match. I think that she will have a little more hp and attack of a normal Fortune, so can also grant permanent enrage to every Ms Fortune, both teammembers and enemy. About buff and debuff, maybe something related to increase/nullify critical hits/damage.
