So human have abillity to transform i to a super saiyan but u most to wish from shenron.
I heard when u become a level 50 you automaticly get a super saiyan transformation.
I mean is that true if it is is that mean we are some kinda half halfed or half saiyan ???
Or maybe not???
Sorry if u dont understand some words i cannot see what i type!!

No you don´t, you have to get 7 dragon balls and be lvl 40 to wish for ssj.
On anime when they turn on ssj they became very much strong because they are saiyans, but in game are humans not pure saiyans so your power will increase only a little.

Maybe in the past ha ?

nope

In the past you had to be level 50 and have all 7 dragonballs to wish for super saiyan
