Super Battletoads Edit
- General Slaughter - Launched into the vacuum of space by Rash, Zitz, and Pimple
- Karnath - Decapitated by Rash, Zitz, and Pimple
- Scuzz - Was presumably either burned alive or suffocated in space after the Robo Rat machine was destroyed.
- Big Blagg - Stomach ruptured in battle by Rash, Zitz, and Pimple, and was kicked presumably into space.
- Robo-Manus - Brain set on fire by Rash, Zitz, and Pimple, causing him to blow up.
