As suggested before well I will suggest it one more but with how to balance them too.
Ultimate Sacrifice: Takes 5 seconds to charge. Kill's all the people in a very big radius but not all the map. Cooldown of lets say 20 mins. It kills its user. Only performable at SSJ2 Majin. Also it will only kill people with powerlevel higher than you and with HP lower than yourself.
This thing with PL higher than you and HP lower than yourself it will make it unspammable at 1 hp or just when gonna die also its made for power full foes to surprise them.
Ring Attack: Only usable at SSJ2 Majin. Its a little slower than a ki blast. It decreases Half KI. It will only work if theres a vertical obstacle in back of the enemy to catch him with the ring. If hes succesfully catched you can only attack him with prepunch. Also to the one which is catched with this attack it will appear a struggle bar and according he's power level and to the enemy power level he would keep LMB pressed to escape it. If he succesfully escapes before the enemy attacks he could spring back and basic melee him 4 times in a row. Also if the Enemy (SSJ2 Majin Vegeta) will prepunch them after the prepunch the enemy springs back up but with normal basic melee hit.
Revive Mode

Well in this game mode who dies will only play again if its revived with the dragon ballz
