Aggregation

Aggregation (シュウゴウタイ, Shūgōtai) is a Mysterious Being.

Appearance
Aggregation is a massive floating cluster of countless numbers of insects. It appears as a vaguely spherical cloud floating in the air, but it only has a shape when the insects it's made of are close to one another. As soon as the swarm attacks, the size of the cloud decreases immediately.

Neo Heroes Showcase Arc
Tatsumaki is seen engaging Aggregation, suspending it in the air before the mass seems to leap towards her. The monster was later killed by Tatsumaki.

Abilities and Powers
Flight: As a cluster of flying insects, Aggregation can fly through the air.

Trivia

 * Aggregation's appearance and disaster level might be based on the dangerous swarm behavior of locusts, one of the Egyptian Plagues.
 * Being a swarm of insects, Tatsumaki finds Aggregation disgusting.
