Insect

Insect is the UMA that embodies insects.

Appearance
Insect resembles a large insect that shares many traits from other existing insects like the dragonfly and Hercules beetle.

Personality
Insect seems to be just a large bug with no real personality of its own, as the only time it has vocalized, it screamed at Andy

Ragnarok Arc
Insect appeared with a bunch of other UMA's that attacked Andy like Gravity and Magma. They tried to attack Andy, but he ended up slicing Insect in half killing them.

Union Arc
Insect was the penalty for not completing a batch of quests from Apocalypse, and due to Fuuko passing on the quests Insect was brought into the 101st loop.

Abilities
Not much is known about Insects abilities however, judging from their size they must be decently powerful. The only concrete power that was shown was the ability to make juniors.
