The Rose City Five are training when word comes in that a super-powered street gang is rumbling in a Swan Island freight yard. The party (sans Shimmer) is driven to the scene where they find the Motor Jokers have just finished crushing the Highway Devils.
Bimbo with mental powers.
Chain-wielding martial artist.
Drain/Aid projector.
Brick.
99's mental powers together with Hex's raw power takes the brick out of the battle early. Flo drains LPs OCV, forcing her to spend most of the combat pushing freight containers around to harass the villains. Bambi controls Quantum, who can't seem to hit anything this fight. Eventually 99 handles Bambi, LP and Hex take out Chains, and Flo gets tagged and goes down. Flo is revived at the end to heal a severely wounded Bambi.
The gang is taken into custody. They reveal that they were given their powers by an untraceable “mad scientist”, but no further clues are forthcoming.
