SP Kid Gohan YEL is basically a Melee version of SP Vegeta PUR, with fairly high Offensive capabilities but poor Defense. His main strength lies in a Strike Attack stat that can be Buffed it multiple times over for even higher Damage output.
While his Health and Defense stats have aged quite a bit, this Fighter has an extremely valuable Z-Ability Buff for Hybrid Saiyans, making him a mainstay on the bench long after his viability on the core has ended.
Finally, SP Kid Gohan YEL holds two Blast Arts Cards, despite being a Strike Fighter. This lowers the probability of drawing Strike Arts Cards as well as his average Damage output.
High Strike Damage Output
SP Kid Gohan YEL’s Strike Attack stat gets several Buffs from his Abilities, which include Main Ability (50%), Unique Abilities (20% and 35%), and Extra Move (20%).
Held Blast Arts Cards
SP Kid Gohan YEL is classified as a Melee Fighter and while his stats stay true to that, his held Arts Cards don’t.
All if his stats--even Buffed as far as they can be--are horribly outdated, making him an extremely core Fighter. Since none of his Moves or Abilities beyond the Z-Ability benefit the Team, he's really only useful on the bench now.
This Tag is very well established and has many Z-Abilities to benefit a Team. There are also tons of SP Fighters that would find SP Kid Gohan YEL's Z-Ability highly useful.
