so people might think why goku or kakarot didn't use his primal super saiyan blue form in the battle against jiren well first off it is straining because he still has a lot to experience using that form and a normal kiaoken would not strain him that much but if he goes beyond 2 he might put too much strain on himself so he doesn't use it aswell(i forgot to mention that super saiyan 4 blue form was a little bit straining so yeah my bad) and also if anyone uses my version please make a better story where there is atleast more action and also when goku was in the past why was he able touch the planet and everything except ki and people well he in a half physical form i guess he could touch a non living stuff that has no lifeforce like a clothing but not plants animals and ki he can't be seen but he didn't know because he thought he can be seen so most of all the sneaking around was basically a waste of time XD
