Titan Eternal

Titan Eternals, also known as the "Titanians" or "Titans", are one of the main subspecies of Eternal found on Saturn's moon Titan. Although the majority of humans are familiar with Earth Eternals there are significant beings born of the Titan Eternals, such as the monstrous Thanos.

Origin
Like all Eternals they are ultimately experiments of the Celestials and are naturally gifted with incredible cosmic-level powers. As such, they've been mistaken for deities, specifically the Titans of Greek mythology, with which they also share their name.
