I used to collect all of the TFs I could, but I started running out of room, so I decided to start collecting just Optimus Prime/Primals and thier repaints, but as of right now, I am running out of room still, but anyway, here is my list of what I have so far: Beast Wars Optimus Primal(Bat) Beast Wars Transmetals Optimus Primal Beast Wars Optimal Optimus Beast Machines Optimus Primal RID Optimus Prime RID Optimus Prime(Mini) RID Scourge(Spychanger) and the Optimus Prime repaint RID Scourge(Destructicon) Machine Wars Optimus Prime Armada Optimus Prime Armada Supercon Optimus Prime and all three of his repaints Universe Optimus Primal and the Beast wars tenth anniversary repaint Commemerative Series Powermaster Optimus Prime w/ Apex Armor Energon Optimus Prime Cybertron Optimus Prime and the Galaxy Force Optimus Prime repaint Cybertron Optimus Prime(Mini) Cybertron Jungle Planet Optimus Prime Alternators Optimus Prime Twentieth Anniversary Optimus Prime w/ Black Gun Classics Optimus Prime Classics Optimus Prime w/ Megatron and DVD Titanium War Within Optimus Prime three inch and six inch Titanium RID Optimus Prime Titanium G1 Optimus Prime and both of his repaints Titanium BW Optimus Primal Titanium Movie Optimus Prime Universe Nemesis Prime Robot Heroes Optimus Prime Robot Heroes Movie Optimus Prime w/ Sword Movie Nightwatch Optimus Prime Leader Class Movie First Strike Optimus Prime FAB Fire Blast Optimus Prime RID R.E.V.

Nice collection, yeah pics are needed. As a primarily Prime collector myself you'd be amazed at the number of Prime you can accumulate yet will always be missing many many more.
