ML Rhino BAF with resculpted head.
Feet from an ML Hulk.

Legion of Superheroes have some characters whose costumes I really dislike, and Blok is one of them. Most of my reading of the comic series came in the 80s and his main costume at that time was ridiculous imo. I went through a search to see if he wore a better costume later or before and finally found a comic panel with one that I thought looked good. I think it only appeared in one or two issues but I'm going with it for my shelf. Pretty much a straight up use of the ML BAF Rhino except with reworked head and addition of texturized Hulk feet because Blok has toes.
