Although there are a total of 20 unused Mini-Cons in the game's data, most of them are just text strings. However, two were extensively worked on before being scrapped. The first one was called "Endgame" and would have summoned large "holes in the fabric of space" that would have sucked enemies and objects into them. The second dropped Mini-Con is called "Bug-Out" and would have called upon "Emergency Warp Gates". Although Endgame was scrapped, his model was reused for in-game Mini-Cons Discord, Twister, and Overwatch.
