He's seen as the most intelligent of the Crea group. Usually seen on his computer and helping Kim Min-Jung with the basics of becoming a Builder. By himself, he likes to sing with a broom, showing his "entertaining side". However, this side of him seems to be outwardly shown when he is in the Builder world as he wears a joker/clown suit that contrasts his usual attitude with others. During his teaching of Min-Jung, he's shown to admire the Builder Red Hammer to an almost obsessive level as his codename Black Hammer was in tribute to the Builder.
He is an original member of Crea.
