Kidd Gruff

Kidd Gruff, known as Kenta Yagi (八木 ケン太, Yagi Kenta) in the original Japanese version, is a young boy from a small town in the Loch Mess area. How he met his FM-ian partner, Goat Foo (ゴート, Gōto), is unknown, but when they combine, they become Kung-Foo Kid, a wood-based martial artist known for his exceptional speed.

Neither Kidd Gruff nor Goat Foo appear in the anime.
