Ok, don';t know if this is stupid or not, but I came up with this idea, and I'm pretty sure it should belong here for safety.
Some Transformers Decepticons land in the Naruto world... and get Therapy-no-Jutsu'd or otherwise befriend someone. Thats not to say that they won't still be them after all, Megatron could be getting close to Naruto to discover the power of the Kyuubi so he can use it, Starscream will probably backstab five people before the story is over, and so on.
The alternate idea I had is each member of the future Team 7 finds 2, per person, amnesic transformers... who's colour scheme is Green and Purple. Thats Right, Team Sevn and their powerful ally, the almighty Devestator!
Crack, of the highest form.
