Insectoid (Ben 10)

These Insectoids are a sapient race of small yellow four-legged insects.

Culture
Because the Atrocians are horrible slobs that 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. Since developing faster than light space travel, Insectoids have started highly successful sanitation services on many other planets.

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

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.

Being their natural predators, Terroranchulas can neutralize an Insectoid's plasma balls with their energy webs. They can also become ensnared in the webs, much like a fly in a spider's web.
