It would be easy enough to do. Start with Trinity and that way they have the parts to just slap onto a Ground Form figure.

Does anyone know what is the rarest Toku figuart at the moment?

It's hard to tell really, chances are it's a dbz one though since Frieza costs a stupid amount nowadays.

Gai, or Genicider. Knight's slowly becoming less rare.

I'd say those are a close second and third to Shin Zangetsu. You can't even FIND him anymore.

Damn, your right. I haven't noticed since it's not something I actively look for, but yeah, it's definitely a tough one to get.

I dunno. I see Shin Zangetsus every so often. Renewal Kabuto on the other hand seems to have just vanished from existence.

He's getting reissued though.

Baron Lemon Energy? They made him just for one show and had maybe 10,000 of him at most.

Uh... Check Mandarake. He's not only fairly common, he's affordable.

Also, I'm pretty sure 10,000 is a sizable number for a figure line, especially one like this.
