Maxilonian

Maxilonians were a squid-like humanoid race from the planet Maxilon that wiped out when one of them named, Gallaxhar destroyed the entire world.

Biology
Like is known about what Maxilonians were like, expect they were a light blue skin, six legs with a single hand on each of them and four eyes. They also apparently drink with their ears instead of just their mouths and presumably some with eating as well.
