Here's my idea on how he might fit in (whether in TF3 or beyond) - The flushing out of Decepticons is a great success - More and more Autobots arrive on earth - One of these: Grimlock - He refuses to scan any vehicles and remains in protoform - Dislikes the way Prime has been working with humans (in building Autobot City? Or sharing Energon as an energy source? Ideas?) - Leads his own faction of newly arrived Autobots against Prime - When a human villain sets up an Autobot for murder (in a conspiracy to drive them away from earth), Prime agrees to a human trial - Grimlock opposes, convinces Ironhide to join his faction - The renegade Autobots stage a rescue of the convicted Autobot - to disastrous results - War between humans & Grimlock faction - Prime reluctantly fights with the humans - Much destruction and bloodshed - Ironhide killed - Prime finally defeats Grimlock - Prime leads Autobots to abandon earth once and for all; gives Sam a device to call for them should the need arise - The human villain wins. Earth is open for Decepticon attacks once more. Opinions? Suggestions? Oppositions?
