Human-like Hollows (earlier episodes)

[Nihonjin]

I was rewatching bleach with a friend of mine (because he following this godlike anime) and I noticed some Shinigami like hollows (with Shunpo (or something similar) O_o).
I was wondering WTF are they?
They reminded me of what Ichigo basically is when his hollow side takes over....
Now I'm thinking they were part of Aizen or Urahara's experiment...
This might actually be a hint at the next arc...(or not -_-').
Because from what I've seen, they're kinda bossing the hollows around sending them on missions sorta like soul society captains (atleast thats the impression I got).... I'm just curious on what you guys think.

i noticed it
and 1 hollow looks like sheik from OOT

i think they are sick experiments of aizen

so hollows that have shinigami powers :P
as we have seen the hollow that killed kaien

[GSurge]

Aizen's doing, I would assume.

[Masaki]

Perhaps Hollows that went Shinigami. And they might be experiments of Urahara.

I seriously hope Bleach doesn't end like Yuyu Hakusho.

[Nihonjin]

Yuyu Hakusho?
Anywayz, those hollows look badass and I hope Kubo has some badass twist involving them in mind XD

Do you mean that group of hollows in Hueco Mundo that were a bunch a tall shadowy figures? Yeah, they seem pretty mysterious.
