Leyon

He was formerly friends with the Blitz Team's Steve Toros until an argument between the two involving being the future husband of a woman (Leena and Leon's mother) caused the irreparable rift. He is associated with the Backdraft Group, although he often tries to recruit pilots to challenge the Blitz Team and avenge him (Harry Champ, the Tigers Team, Brad Hunter). It is believed that his reason for joining the Backdraft Group was influenced by alcoholism. Although he hates Toros, he deeply cares for Leena (he claims she resembles her mother), shown in the instance where he shoved all the other Zoids away with his Whale King to shield her from the massive explosion created by three charged particle cannons. The explosion bore a giant hole on his Whale King and severely injured him, thereafter he told Toros he was leaving the Backdraft Group. from wikipedia
