It was AGL Vegtio and PHY Broly but I guess Gotenks fits well in a "young warrior" catagory the Dokkanfest kid Goku is probably getting (people datamined that catagory before kid Goku got announced so it's likely he'd be the leader for that + missions)
Oh man PHY Broly too.
Would be amazing to actually make him useful again, but unless they change his name he'll never be used by any player that has movie Broly ever again.
