Let's just get it out of the way and call him 6" Titanium Fire Convoy. It totally alleviates any confusion as to who this character is and I really don't think of him as Optimus Prime anyway.
And well... it is my site... so *thhhpppppppt*
6" Titanium Optimus Prime (Fire Convoy) is the 1833rd Transformer that I've acquired.
He looks cool ... still hunting around for him ...
