Not saying I don't understand why a mid-pubescent boy with almost no relations would pick essentially seggs mastery, I get the reasons behind it and all, but when he could use that to get Veteran Operative, Charles Atlas, or get meditation for another power, or even scrap something else as well to get Aura from Rwby to defend from sneak attacks or stuff like flames which is hard to defend from, as is air - especially if used to attack your eyes, or another power like a Breathing Style to massively increase overall power for some time and can be trained to do so permanently, or Haki - of which Conqueror's would likely be able to defeat most people and definitely make an opening against almost anyone, observation with the other perks could probably be developped to a very high level to easily predict attacks from enemies hundreds of meters away or further and possible future sight in due time (which would make you virtually invincible in a world like Avatar as long as you are somewhat strong), or Armament Haki to essentially one-shot most people as long as you land a punch or to defend from most damage. Like, I'm not hating, just saying that even at his age, I think it's kinda stupid, even if I get his reasons and that he's already strong enough that you'd need the very strongest people to even put up a decent fight and he can get more powers at another time.
TFTC, did not read all the list but from the chunk of power i saw pre mending planeswalker was The BEST base for me.He Will have godly potential and Will be able to grow in avatar where his bigest and maybe only enemies(no other being can kill him) is rava and batu and if he side rava he Will be 100% save. Also think It Will be a boring history
