Heed

The Heed are a species of extragalactic conquerors who attempted to invade the Milky Way Galaxy by having their leader pose as an advanced pure-energy "super being" who convinced the galaxy's inhabitants to seek out peace and dismantle their weapons.

Biology
The Heed are hairless bipeds with comically-oversized heads and pale yellow skin. They have two eyes, three nostrils, and three vertical ridges on their foreheads.

History
The Heed leader, Guzelian, used a holographic projection to pose himself as a highly-advanced "super being" made out of pure cosmic energy. In this guise, he sent a telepathic signal to summon the LGMs of Star Command and the Grubs of Planet Z and convince them to make peace, guaranteeing that the two greatest powers in the galaxy would have their defense systems dismantled. Fortunately, Buzz Lightyear of Star Command remained suspicious and found out their true intentions. With no one else in the galaxy aware of what was going on, Lightyear and Emperor Zurg formed an unlikely alliance to fight off the Heed.
