Cyborg 009

Nine young people were turned into cyborgs by a company trying to take over the world. They have defeated this company and are now using their super powers to protect the world.

Cyborg 009 is a side-scrolling run-and-gun action game from BEC based on the anime and manga of the same name. The player can control up to three of eight cyborg agents for each stage, each of which has their own separate set of powers. The player can alternate at any time between the three agents they selected, though as all three share a health and "SP" bar (which determines how often they can use special abilities) there's little point to switching out a character if they are badly hurt.
