Optimus Prime - All movieverse except for one lost Armada DLX (I think it was refered to as "Bendy Bus Prime") Optimus Prime.
Unfortunatly,probably BB just because they make so damn much of him that there's always at least one that appeals to me ,though some are either broken or missing pieces . Megatron and Sideswipe are up there too Bumblebee: -Classic Camaro(Broken) -Animated(Broken and missing) -Rotf Deluxe -Battlefield(Missing pieces,shit figure) -Battle Blades(purposely headless in car mode) -Dotm Deluxe(Has Battle blade head) -Nitro Sideswipe: -Rotf deluxe -Sidearm -Dotm Deluxe(Fun fact:Classic Camaro BB pistols fit in Dotm Swipe's hands nicely ) Megatron: -Rotf Voyager -Wfc deluxe -Dotm Voyager
Probably Bumblebee...let's count: -Animated Deluxe BB -Animated Activators Bumblebee -RTS Deluxe BB -Generations WFC BB -Movie Deluxe Concept Camaro BB -ROTF Preview BB -HFTD BBBB -United Deluxe BB I also should have a lot of Optimus Primes...movie Leader, ROTF Leader, Titanium, Henkei Voyager, Movie Voyager, Animated Deluxe, Animated Voyager, Generations WFC, Titanium statue, ,movie preview, and a movie legends sized one that was on a birthday cake. So yeah I actually have more Optimus Primes. So my top 5, from most to least seem to be: 1. Optimus Prime 2. Bumblebee 3. Megatron 4. Starscream 5. I dunno, maybe Jazz?
Blackarchnia (TM2 & BM), BW Megatron (T-Rex & Croc), BW Optimus (ape & bat), Mixmaster (G2 & ROTF), Bonecrusher (G1 & G2), Bumblebee (G2 & Gold Legends), Optimus Prime (G2 with G1 body & Action Master), Rodimus Prime (RTS & G1). ... yep, I've got 2 of those characters. Also to Bountyan, planning to get the Cyberfire BB? I know I am.
I also want to add that I have 2 Ironhide's, Ratchet's, Sideswipes, Jolt's, and Bumblebee's and I had 2 Megatron's.
Optimus Prime ROTF Leader DOTM Deluxe DOTM Cyberverse commander ROTF Legends WFC Deluxe Mini Prime (the one that came with ROTF Stratosphere).
Probably Optimus, just because there've been so many done in each series that I collect. Prowl and Bumblebee are close runners up.
Starscream. Got Movie Leader, both Voyagers, two versions of the Legends, Legion with throne-ship, that protoform version, FAB, Animated Voyager, and am eagerly awaiting for the Prime Voyager. Granted half of those are packed away somewhere...
Well, I almost said none, as I have no doubles of a character, but then I remembered I have RTS Legends Starscream and HFTD Leader Starscream, if that counts.
Most definitely Starscream. There is no close second of anything from any other line, series, etc. that I collect.
