Zi-O vs Decade: 7 Zi-O
Decade vs Zi-O: Decade Kan's Death Game

Okay so for Zi-O vs Decade, is written 7 Zi-O ? Wut ?

Okay TOEI you need to STOP adding different versions of Sougo. First we have the normal Sougo, Mirror World Sougo, Ohma Zi-O, and Quartzer Sougo AND NOW SIX DIFFERENT SOUGO!? Or these six Sougo might just some references to japanese dramas i think ?

But seriously STOP with these different versions of SOUGOOOOOO!!!!!!!!!
