This may be blasphemous, but I'm not all that crazy about Siege Megatron. I'm also not that crazy about Titans Return Megatron. Ssssoooooo I decided to mash 'em up. I'm pretty happy with the result. I chopped off Siege Megs' head and made a Titanmaster port by drilling a hole and fitting a Zoids Blox rubber plug into it. I also drilled a hole in the back of his fusion cannon which, luckily, worked perfectly to accommodate TR Megs' bathtub gun. (While I was at it, I clipped the tabs on the backs of his hands so they can fold all the way out.) For the Titanmaster, I used the faceplate of TR Megs, the head of TR Nucleon, and the rest is TR Ptero. The colors don't exactly match Siege Megs, but they're good enough. The tank mode isn't quite perfect—the fusion cannon is fractionally too wide, making the arms in turret mode unable to align just right—but it's still very close and I'm satisfied.
