Yoshiro Yagima

Yoshiro Yagima, also known as the Needle-Point Hero: Porcupine (シャープヒーローヤマアラシ) is a student in Class 1-A at U.A. High School, training to become a Pro Hero.

Appearance
Minoru is a very short teenage boy with a large, round head, and rather puffy cheeks. His nose is small, stubby and points slightly upwards, and he has an unusually distinguishable philtrum, oval-shaped eyes with large, black pupils, and notably thin eyebrows. He has four large boysenberry purple and black spikes in something resembling a mohawk where his hair should be.

His hero costume is very simplistic, consisting only of a brown shirt and mask with a yellow cape, boots, and gloves. His pants are white with a lighter brown trim, and they stick out quite a lot around his waist. Prior to the Joint Training Battle, he added a horn-like detail that is propped up on his hair, contributing to the porcupine theme of his costume.

Quirk
Spike Burst (スパイクバースト): Yoshiro's Quirk allows him to produce and pluck spiked-shaped objects from his head; the spikes grow back just as fast as they're plucked. The spikes are incredibly sharp and will stab any surface; the sole exception being Yoshiro himself, as he just bounces off them. The duration of their adhesive quality is determined by his overall health. He can pull a large amount of these objects from his head; however, if he plucks too many, it will cause him to start bleeding from his head.

As part of his training, Yoshiro continuously pulled off the spikes on his head, to increase their adhesiveness, strengthen his scalp, and reduce the risk of bleeding from his head, despite suffering from the said injury during his training.
