From left to right: Kit, Dubcee, Merc, and Amy.

My bud  dubcee wanted me to design his other two characters, Merc and Amy in this style, so I took the opportunity to give Kit and Dubcee a bit of a redesign too.

Merc is the scientist who built Dubcee and Amy for the galactic police force. She based Dubcee's body on her own, then added gigantic boobs, because gigantic boobs are awesome. She met Kit when she came to pick up Dubcee, her new partner. They became friends soon after. Merc is a terrible workaholic. The others have to drag her out of her lab, frequently.

Amy was built after Kit and Dubcee became partners. Merc based her body on Kit's. She has vast strength, but is extremely reckless. She tries to solve most of her problems by hitting them. She's also very rebellious, and refuses to take orders from just about anyone. Kit is practically the only person she'll actually listen to.
