Atasian

The Atasians (commonly known as the Highbreed) are a race from the planet Augstaka who believed that their DNA was the purest of all living species and sought to cleanse the galaxy of lower life forms.

Powers and abilities
The Highbreed species possesses great physical strength and endurance and it has been shown that they can even take on opponents twice their size.

The Highbreed can shoot their fingertips like darts and quickly regenerate them. They also sport wings, which they can use for flight.

It has been shown that they can draw water from the ground using their tendrils from their abdominal area in the most arid areas.

Weaknesses
The Highbreed are extremely thermophobic and cannot work in conditions that have high temperatures. However, they do not appear to have physical weaknesses and are oddly capable of walking through fire unharmed.

Due to generations of inbreeding, their immune systems are compromised, which means that any form of simple diseases that "mutts" are immune to becomes a massive problem to the Highbreed.

History
The Highbreed are hyper-evolved plant life with a very fierce belief in racial purity, more so than most Humans. Unfortunately, they reduced themselves to inbreeding, which rendered them completely sterile and vulnerable to infection. In effect, the species was dying out and they wanted to take the rest of the universe with them.

The Highbreed traveled to Earth to eliminate mankind, creating the DNAliens using Xenocites to do all their dirty work. However, Ben Tennyson used the prototype Omnitrix's DNA repair function to save them. Despite their horrified reactions to their now colorful bodies, Reinrassic III explained to his brethren that Ben had given them a chance to live, having been grateful of Ben for repairing his arm in the past. Moved by Reinrassic's words, the Highbreed called off their attacks.
