Well sorry for the long wait guys, here he is... The white demon clan Arcosian leader!!!
I hope I get the time to create Dragon Ball Hell Fighters manga
-This transformation is the most terrifying form ever existed besides the legendary super saiyan [link]
-Please refer to this [link]
for his powerlevel.
-He commanded Cooler, Frieza, The FCK and Cell Family.
-His skin is invulnerable that even an attack from Gogeta SSJ4 (Big Bang Kamehameha) is useless.
-His IQ level is far above that tuffle clan.
-The reason why King Cold didn't transform into this form is because this transformation is so powerful that he accidentally
destroy his homeworld and vow to never transform into this again, but since he is now dead, he can use this transformation in hell but not in the living world.
-King Cold is the only one who can transform into this form, because he is the prodigy of the Arcosian race.
