Technician

My first possible character is a mid range boss enemy, a Technician.
He is slow and not very strong but he quickly creates agile little explosive enemies that charge at the player in rapid waves. He is a lizard-like fellow with a robotic leg which he fitted himself after losing a drunken bet with his father, insisting that if he chopped it off it was sure to grow back.

He has two large canisters on his back, the first is filled with Electric pulse shrimp and the second with a volatile explosive swamp liquid akin to nitro glycerine. The Shrimp soak up the explosive liquid in the dispensing capsule. The technician quickly affixes robotic legs to the shrimp which are coded to run toward the player. When the shrimp hits any surface it produces a defensive shock and explodes.
When the player defeats this boss he/she can re-purpose the technician's gear into a portable explosive shrimp flinger that behaves much like a grenade launcher. or something.

I have no idea how this would work as an action figure..
