Tensei Iida

As the former Pro Hero known as Ingenium, this engine-equipped veteran serves as the inspiring older brother to Tenya Iida. Though he shares his sibling's sharp, square features and spiky black hair, his unique Quirk manifests through exhaust pipes located at his elbows rather than his calves. During his time in the hero industry, he even attempted to recruit the talented Koichi to his agency, though he ultimately withdrew the offer after discovering the young man's vigilante activities.
