Junior

if he was In the tier he would be 900 leagues above the farmer with the shotgun but S+ class seems to be the highest

Junior‘s Real name is Brastin he is the first born son of Bulma and Vegeta, Vegeta had to argue with Bulma to choose his name Vegeta named him Brastin and Bulma just called him Junior Vegeta visions Junior as the perfect son but as for trunks he visions Trunks as a failure Trunks and Junior got along very well despite being brothers the only difference between the two is Junior was born a power level of 9,900,000,000 which is pretty impressive for a 1 year old but years later Junior got stronger and stronger the day he went super saiyan was the day that surpassed the strength of a super saiyan 3 Junior then unlocked other forms such as super saiyan 2 , super saiyan 3 even super saiyan god super saiyan blue and super saiyan blue Evolution but he only got super saiyan blue because he went on 999 Centillion times gravity which allowed him to tap into the super saiyan blue Evolution form but something was off about that form it seemed that he had combined super saiyan blue Evolution along with super saiyan blue and super saiyan god which allowed him to access an extremely powerful form which he called super saiyan grand Evolution in this form his strength 900 novemnonagintillion times greater than El Tio it also gives him Unlimited Stamina and his power never decreases it’s pretty much like an almighty form that is unbeatable
