User blog comment:TVthePunisher/Chapter 415 - Deicide 17...and Kubo trolled again.../@comment-1982694-20100807055620

This chapter confirmed it for me. I still think Aizen is somehow based on Sephiroth as far as the transformations go:

Bizzaro Sephiroth=Pupa stage Aizen Safer Sephiroth= Fully transformed Aizen One-winged Angel Sephiroth=Butterflaizen(Yeah, thank you Mohrpheus. I'm loving this)

Although the above is irrelevant so you can go ahead and skip that.

Personally, I liked this chapter. Maxed out, Overpowered Aizen, for me, only means a much better victory when Ichigo kicks his ass. As for Gin, meh. I never really thought much of the guy. Whether or not Gin's dead, I'm saying this anyway. At least Aizen made it quick. Rangiku, yeah, it's definitely possible that she's still alive. I mean, who really knows other than Kubo?

If there's one thing I'm mad about when it comes to this chapter(And I always find something that makes me angry), it has to be that Butterflaizen can use the hogyoku no matter where-ever it is and whoever has it. I mean, I'm okay with surprises, but that really does put Butterflaizen over the top.

That being said, this chapter brought more to the table than I expected. I'll give it a 4.5/5 to be fair.
