Dr. Grenouille's 4th robot master Horn Man was based on the theme of a horned toad. Originally designed at the behest of the already forming Anura Unit — Frog Man, Toad Man and Poison Man — Horn Man was intended to complement the other members' abilities. He was given a stealth focus and programmed for ninjutsu. His various spines covering his body are in actuality kunai. He is also armed with a pair of high-pressure blood beams alongside his head.
Horn Man is an agile machine and is an expert leaper and jumper. He will often dash around his arena, curling into a ball and firing spines or throwing them while attached to a wall. His blood beams are quite fast-firing, though that is not to say that they are rapid-fire; they simply fire at a quick velocity, making it difficult for his enemies to dodge.
He was eventually decommissioned by Mega Man along with the rest of the Anura Unit.
