Insectoid (Ben 10)

Insectoids are a sapient race of yellow four-legged insects originally from an unknown planet before relocating to Atrocius 0.

Anatomy
Insectoids are small yellow insect-like aliens with black eyes, green pupils, four pointed legs, a beak, and a large crest-shaped antenna.

Ecology
Insectoids are preyed on by Terroranchulas, who can trap Insectoids and neutralize their plasma balls using their energy webs.

Powers and abilities
Insectoids can spit sticky green balls of plasma that they use to absorb matter with. The more matter is absorbed, the bigger the ball becomes. Upon impact, the ball will explode, with the explosion radius dependent on the size of the plasma ball.

An Insectoid's plasma balls can absorb energy, including an Aerophibian's neuroshock blasts and a Prypiatosian-B's radioactive beams.

Insectoids can alternatively spit streams of plasma, which are strong enough to hold a Tetramand.

Much like Earth insects, Insectoids are capable of scaling vertical surfaces and can fit into tight spaces as a result of their small size.

Insectoids are incredibly agile, capable of dodging sniper fire with grace and ease.

Weaknesses
The plasma balls are very sticky and Insectoids can become stuck in them or subjected to their explosions if the balls are reflected back at them.

Insectoids are vulnerable against Terroranchulas, whose energy webs can trap them like flies caught in a spider's web. These energy webs can also neutralize an Insectoid's plasma balls.

Culture and society
Because the Atrocians are unable to clean up after themselves, the Insectoids evolved as a natural sanitation solution to the Atrocian garbage problem. Once a week, Insectoids roll through Atrocian villages, sticky-balling up all the filth before blowing them up. After they developed faster than light space travel, Insectoids have started highly successful sanitation services on other planets.

History
The Insectoids came to Atrocius 0 after it was abandoned thousands of years ago. They have developed a symbiotic relationship with the Atrocians after the latter settled on other planets.
