Your favorite dark organisation of beyblade?

what is your favorite bad organisation of beyblade? the first generation with the Demolition Boys and biovolt, the second with metal fight fusion and the dark nebula/ masters and the starbreakers and co/4-D and the bladers of nemesis; or the third generation whit zero-g and the DNA?! personnaly my favorite dark organisation is the dark nebula :p
The Dark Nebula was pretty interesting as were the Starbreakers to me, but I can't take any "evil organization" in Beyblade seriously when I remember it has to do with them playing spinning tops, haha.
Dr. Ziggurat's HD Academy was pretty cool. Created strong bladers like Damian, Jack, Zeo, and Faust.
Wait, don't we already have something like this?
