I did cave and open up Megatron Megabolt yesterday. He's pretty cool. Like Armada Prime, this is a mold I've owned for a while (since 2003 or so), but I now own it in its "proper" colors.
Oh, and the TM II Megatron/BIAB Magnus & Treadshot package has arrived. Both look great. The same seller is also sending me BM Blackarachnia (I use Universe Blackarachnia as Crystal Widow; they look about the same). I'm hoping to win a bunch more BM stuff from him.
