mystery arrancar!

ok heres an interesting thing i stumbled upon, was re-reading the old chapters of bleach as one occasionally does and i noticed a couple of arrancar that i didnt notice before:

Spoiler:

and

Spoiler:

hmmmm any ideas? theories? answers? :scratch: (From Chapter 198 if you want to see for yourself)

*sits and thinks*

Maybe there will be something behind there beings in the future? You know? It seems the tops are with Hallibel or something. She looks a little different. Is that the past? Like when they are reminiscing or something? Anyway, i wonder what they are there for. Maybe a Cameo? Or something else......

maybe a cameo... maybe simply forgotten about..

they look a little bit freakier compared to the rest of the arrancar we've seen so far... maybe these are the vasto lordes or whatever.... i dunno really all guess work here so... ho hum
