Now i like the idea that JynX about the lgendary ssj (http://main.jingames.net/forums/topic/legendary-super-saiyan-4/), so i think they should really be omplomented.
1) Weighted clothes
It would be a little bit cooler if weighted affected ones power leve/battle power.
2) Kais world
a place were you could train with the kais, and maybe pull the Z-Sword and get a big boost
3) A “100%” transformation for the arconian race
Literrally a transformation that makes you buffer and a big power boost
