In Japan, yes. In Japan, Autobots are Cybertrons, Decepticons are Destrons, Cybertron (The planet) is Seibertron, Optimus Prime is Convoy, and you'll never see me using any of those terms ever. Nothing against, Japan, really, I love that country, but I am going to use the American terms for all time.
Not anymore. Ever since the Movie line, Japan has gradually began moving over to using American names now. Convoy is now "Optimus Prime" (Oputimasu Puraimu), Cybertrons are now "Autobots" (Ōtobotto), Destrons are now "Decepticons" (Diseputikon), and so on and so forth. It's rare nowadays for TakaraTomy to use their old terms again.
My point still stands. A few years ago, I'd be entirely correct. Unfortunately, my time machine isn't finished yet, still working on the "Relative Dimensions In Space" aspect.
Wow Sabrblade - too bad there's not a Transformers Jeopardy show around! And Shadowman - your title (God Of Transformers) holds true! Anywho, to help with your "Relative Dimensions" issue, I have a modified DeLorean DMC-12 sitting in my garage - maybe I can ship you over the flux capacitor ...the transmission is shot (I blew it out trying to go back and help Bay write a better story for RoTF) haha. Plus, I need new tires on the thing...so I was just going to sell it for parts anyway. ; )
Oh, and You might NOT be a True Transformers Fan...if:
You think the train from BTF III was Astrotrain!
(Though that would have been pretty funny and yet really, really cool!)
