WARNING: Many very large images follow!This will be the LAST cosplay post from Anime Expo, so...sorry, those of you who want more, and you're welcome, those of you who are sick of it!
But this collection is it. The ultimate. These are the costumes that blew me away for one reason or another, and there aren't that many, because I've been going to anime conventions for ten years and I'm a jaded, bitter old bitch. (That's not true. I still get excited over stuff. But I'm still not SURPRISED by stuff much.)
Anyway, I'll quit dawdling and get to the pictures! The first two you'll have seen before, of course.

Sexy woman, giant gun...no clue who it is, but it's awesome.

Excalibur, Excalibuuur! o/~

Black Lagoon that isn't Revy ftw.

Not amazing at first glance, until you realize she really DID hurt her foot. Excessive devotion, but awesome cosplay.

I got an interview with the Rock. See above.

NIP SLIP! Seriously though, dude has NICE legs.

Who would ever have thought to cosplay Hayao Miyazaki? My personal favorite.

HOLY SHIT IT'S THE !@#$ING SHREDDER!

Neat execution.

Baby Haruhi was snapped on the escalator, so sorry for the blurry, but too cute to pass up!

Samurai Vader!

Amaaaaaazing prop work.

She has this character down pat looks-wise.

No clue what this is, but it's kinda neat. Wish you could see the tail better.

Princess @#$!ing Knight! Oh my god!
Whew! Okay. It's over'd!
It's also very, VERY cool to see cosplay from pre-2000 series. I remember attending AX several years back and nearly fangasm-ing over Iria, Sharon Apple and that girl robot whassername from Yasuomi Umetsu's "Presence"; the latter was such a great surprise.
Kind of saddened at the lack of Noa Izumi and Birdy cosplay.
I feel so damn old.
