Well, by that logic B214, Vali shouldn't be considered the strongest then, because the fights alongside Albion just like Ise fights alongside Ddraig. Vali almost exclusively uses Albion to fight, sure he has other skills like magic, but when you get right down to it, if you fight him, you will be seeing more of Divine Dividing than anything.

Honestly, I feel Ddraig calling Ise the "weakest" in the latest chapters wasn't meant to be taken seriously, I feel he was referencing Ise's original strength. Ise wasn't actually the weakest, in fact, you could almost consider it teasing, because Ise has in fact mastered Boosted Gear like no other possessor has.

Also, like I said, its never said Belzard was Vasco level, or even close. The only reason he was said to be strongest was because he beat two White Dragons, and that was it, they never said he had Ultimate-Class level power. We are just assuming he is that strong, there is no real proof.

After all, one would imagine that if he was that powerful, he should have been able to control Juggernaut Drive like Vali. But as far as we know, all the previous possessors were killed by Juggernaut Drive, Belzard included.
