Here's a LEGO MODOK I just made.

Here's an entirely brick-built MODOK that doesn't use any printed pieces or stickers. The head and arms have a good amount of articulation, despite that I don't really think the head should have any at all. I have no particular affinity for MODOK, it just came to me that his face could probably be made using Brickheadz techniques. It started off as just a modification of the official MODOK from the Avengers Helicarrier set but quickly became its own thing that's totally distinct from that...
