Maxilonian

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

Biology
Like is known about what Maxilonians were like, except that they were a race with 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 the same with eating as well.
