Mondo Owada is the leader of a biker gang. He has slightly tanned skin and a tall, muscular build which gives him a bulky figure. He wears his hair as a dark-brown punch perm with a styled-1960s pompadour. His pompadour is approximately fourteen inches when compared with his shoulder width which can be estimated to be around fourteen inches. He has a deep-ridged black eye-line circling his purple eyes, which gives him an intimidating appearance. Behaving like a stereotypical delinquent, Mondo is foul-mouthed and can come off as a rude and intimidating individual. He is very easy to provoke, and will not hesitate to resort to violence if he starts to lose his patience. Mondo states that he tends to be very nervous around girls that he likes, causing him to raise his voice and ultimately scare them away, something that has happened at least 10 times already. This potentially shows that Mondo is shy around new people and is unaware of how to relinquish his ruffian type personality while in calmer situations. Mondo has a soft spot for dogs.
