Hit this up, and the one I can recommend is the Transformers Animated Optimus Prime… the best looking Optimus Prime I’ve ever owned. Hook it up! Oh… and it’s just me, but I love Ninja Jazz. He looks badass alongside my Kamen Rider IXA. 😉

EDIT: Wow! Great job everyone! Looks like they blasted through their Optimuses and Jazzes. Here’s one other recommendation… Transformers Animated Starscreem is phenomenal. This is one I wish I had, but never got. Vangelus seems to dig it. 😀
