You want a lame idea for a comic character? How about we take the dead leader of the bad robots and stick him to the dead medic of the good robots (who was the main character in many early issues) and have the combo become a highly destructive zombie. This monstrosity popped up in Transformers 69 and continued to hang around for a couple of issues. Eventually everyone gets "unfused" and "undead" much to all our relief.
