[Answered]  Little dissapointed with the Zero-G recently

I just finished whole Zero-G series and just realized that a few beys were never released like the Phantom Fenrir, Berserker Byakko, and another one which the owner had a mohawk with a bird bey. I just don't get why TT didn't released those beys. I know that I made a Byakko bey from the bey warriors, but there is no beywarriors for Phantom Fenrir. Why TT, why u do this to us?
Beyblade sales were so low by the end of Zero-G that Takara-Tomy canceled their last few releases.
