Ada is a fast, but low defense legend who features the Spear and Blasters as her weapons. She can be unlocked for 3900 gold. Ada has a cyberpunk theme in her appearance, with a striking magenta and green colour across her entire look. This street style look, however, doesn't fully convey the cybernetic modifications that have been implemented under her skin. She has had a turbulent history with the shady Meyers Baby Food Corporation of a corrupt future society, and brings with her both her computer modified reflexes and a lifetime's fighting experience to demonstrate her skill and cunning in the eternal tournament.
The shadowy corporations of a corrupt future trained Ada to be the worst thing that ever happened to them. - Mallhalla purchase description
