And the last one!
Dr. Prion, while being sure that his work on Flow won't come undone, still wants to put a failsafe. Someone to protect his perfect weapon from forming different opinion on the world. Through some shady and illegal shenanigans, he got his hands on a stolen schematic crated by an engineer genius Dr. Ivo "Eggman" Robotnik. It took Prion some time to figure out, but eventually he created Mecha Raptor.

It has no personality and it's only priority is to ensure Flow's happiness and protection.
