Real name: Ego (aliases include Nu-Xandar and the Living Planet)
Place of birth:: The Black Galaxy
Powers: It can shift its surface to appear as if it had a giant face and even grow enormous tentacles
First appeared: 1966 in Thor No. 132
Bio: This planet-size entity is somewhat difficult to define, considering its strength and intelligence are incalculable, but it does have organ-like masses under its surface and the ability to move itself. Ego’s plot for interstellar conquest saw him matched against Thor, the God of Thunder. Ego was defeated but still maintains the ability to morph into a paradise in order to lure unsuspecting travelers to their doom, and to masquerade as a barren world. It is also known for tapping energy sources from stars and other celestial bodies and absorbing their power for itself. In short: Earth, watch your back.
