Abyo is very outgoing, competitive, stubborn, energetic, and excitable. He's Garu's best friend and he's also good friends with Pucca and Ching. A practitioner of Kung-Fu, Abyo uses nunchucks as weapons. Abyo's signature move is a running gag in the series: he jumps up, yells "Hi-Ya!", and rips off his shirt at least once in every episode. If he can't rip his shirt off, he settles for whatever else he happens to be wearing, resulting in him severely embarrassing himself in public.
His physical appearance is an homage to martial arts icon Bruce Lee, but unlike the late martial artist, Abyo's personality is very headstrong and impulsive and it is with this kind of attitude that he is often left with the shorter end of the stick.
Abyo is the son of Bruce, the police chief of Sooga. He trains under Chang at the Turtle Training hall with Garu, Ching, and Ssoso. He's also a bit of a womanizer, yet usually ignores Ching's crush on him, much to her frustration; this slightly wears off when she proves to be one really good martial artist and saves Abyo's life, though. Ring Ring has a crush on him also (in Ching It On) but he actually returns the favor. When Muji tried to lower Abyo into a tub of boiling acid, Ching cut off Muji's moustache (his only weakness) and saved Abyo. He has also willingly kissed Ching in Misplaced Face. He also kissed Pucca in Abra Ca Pucca when he was put under a love spell by Pucca with Santa's wand (when she had, in fact, been trying to put the spell on Garu). It is revealed in A Better Boyfriend that he is allergic to mustard which causes his head to grow big, red and swollen. Throughout the series, Abyo is shown to be a bit of a show-off.
