Answer: Maggie's Ultimate ability Wrecking Ball allows her to throw a disruptive ball that releases speed-boosting pads and detonates near any enemies in its path for a maximum of 20 damage. It's worth noting, the ball bounces off floors, ceilings, and walls and has a 90-second cooldown.
Although she's painted as a villain by the Syndicate, Maggie is also seen as a hero by many. She's also a New Zealand Maori, and this was an aspect of her background Respawn says was determined to get right.
