Damn, & He's obviously the only other Anime/Manga Nodachi wielder that would be of note (There actually aren't that many Nodachi wielders in animation.)

My only other guesses for Smoke's foe are either Metal Sonic, or Gamma. (Though I have a feeling both are just as wrong as Shadow...)

Wouldn't Scyther have a disadvantage towards a KAIJU like Kamacuras? Scyther is typically around regular human size, while Kamacuras is like an 18 wheeler to it...
