Tetramands are an alien race from Cartoon Network's Ben 10 franchise. When Ben Tennyson himself is a Tetramand, the picture should also get the four_arms_(ben_10) tag.

They are a buff and bulky species. Most Tetramands are red, but blue and brown ones have been seen. Tetramands have spikes on their arms, and sometimes on their heads. They have two front toes on each foot. Tetramands appear to have an additional set of smaller pectoral muscles below their primary set to help move their second set of arms.

Some Tetramands have black hair which becomes grey when they are older, but most male Tetramands lack hair.

Younger Tetramands are skinnier than adults, and have disproportionately larger eyes and heads.
