This trait's concept is inspired on Goku and Vegeta relationship on the series. You'll have to pick a rival (from your race or froma different one, don't know which fits the most), from whom you would gains some aditional BP from sparring and/or zenkai. Another appoach is to give each other a skill with a fair cooldown (30 mins, 1h, 1h30mins) that would put both on a special state where both of them get a fair boost on BP gains when sparring.
The trait would keep each one as the other's rival, meaning that a person can only have 1 rival of this kind. Additonally, to purchase this trait, it would be similar to Fusion, you need to get close to that person, and he/she have to accept the proposition. They also lose a Trait points
