Actually, the coolest Transformer would be one that turns into a Nintendo console!
Heck, there could be an NES (Nintendimus Prime), a Game Boy (Gambleboy), a SNES (Superhide), an N64 (Natchet 64) and a Virtual Boy (Vrazz).
Their Decepticons would all be rival consoles, like Segatron, and Sonyscream.
