This variant of Vegeta comes from the DBZ series when he was killed by Frieza but later brought back with the help of the dragon balls.
His toolkit is completely focused on Offense and Buffing Saiyans at the expense of any Defensive capabilities.
Overall, he would be a great glass cannon Fighter if his stats weren’t so power crept.
Blast Buffing Toolkit
Every single one of EX Vegeta GRN’s Buffs his Blast Attack Stat. Assuming he was able to get all five active at the same time and his star levels were maxed out, EX Vegeta GRN would be able to land a Blast Attack with +90% Damage on top of a 23% Buffed base stat.
Glass cannon is an understatement with this one. Since all his Buffs go to Offense, EX Vegeta GRN relies on Equips and Team Synergy to improve his poor Defense stats.
However, because of his held Strike Arts Cards and single stat Buffing Z-Ability, this Fighter isn’t likely to be put in the core and possibly not even the bench.
Since he’s not a Super Saiyan, Frieza Force, or Goku variant, EX Vegeta GRN doesn’t have a lot of Equips and what he does have aren’t all completely optimized to his toolkit.
