MHA alien

your an alien from a far away planet called yxalag, when you were around freshman age in human years you went down to earth to learn more about quirks and how the humans evolved. so you enrolled into UA, and you almost immediately got accepted, because you have a very strong 'quirk' (all yxalagians have it). you can hear and create radiowaves through your antennae.

but... recently the scientists at UA discovered life, and maybe even your colony on your planet.

aizawa: nervously explaining, trying to keep his cool "you must realize how dangerous these aliens can be, this planet isnt very far. they might have technologies to study or harm us."
