does anyone know who this STEOE enemy is?

Billy the killer machine

Infected Thomas concept for a possible future TTSE fan game, credits to @alexandrethebluediesel for design ideas

the two most powerful characters in the TTSE universe:

Killer Cellphone (My Terrortubbie OC) Sprite

Angry Tubby (My Terrortubbie OC) And Horrotubbies (Terrortubbies alternative version)

I found this image of this TTSE character, I think she would appear on a TTSE 2 map
