Rockabilly musician and voice of proudly ignorant Georgia squid Early Cuyler, Unknown Hinson returned to Dragon*Con this year for a performance during the Adult Swim Squidbillies panel.

Hinson, who shaved his iconic sideburns much to the dismay of those in the audience, played a three-song set for the crowd before joining the entire cast of Squidbillies in an unrehearsed reading of a script for a future episode of the show.

While we didn’t record the cast reading, we did manage to get coverage of Hinson’s performance, which we’ve embedded in the three videos below.

Whenever Adult Swim hosts a panel at Dragon*Con, it’s safe to assume they’ve brought their “A” games — and by that I mean those in attendance will get an exclusive performance and most likely will leave laughing their asses off.

Specifically, I’m referring to the team behind Aqua Teen Hunger Force and Squidbillies, who’s panel opened with show creator and voice actor Dave Willis taking stage to recite a monologue performed by a puppet version of Carl. Soon there after, voice talent Dana Snyder joined with a Master Shake puppet.

The puppets — presumably from the ATHF live action show tour Willis and Snyder did earlier in the year — were actually a genius idea to associate the voices with the characters (since voice actors aren’t always easy to identify).

Ever since Marvel Entertainment confirmed that Joss Whedon had been chosen to direct their big budget Avengers film, the fan community has vocalized their support or distaste of the decision.

The point being? There is a renewed interest in all things Avengers.

For proof, one need only look to the attendees of Dragon*Con 2010, who showed off a plethora of well crafted costumes this year that featured Avengers both new and old.

We’ve attempted to capture a handful of what we saw while covering the event this past weekend in the photo gallery embedded below.

It’s also worth noting that Geeks of Doom photographer Derek Deweese let his fanboyism run wild in some of these photos by attempting to mirror popular comic book covers. (Neither of us remember the issue of The Ultimates where Captain America points to the “A” on his helmet. If you know the cover we’re talking about then by all means educate us in the Comments section below.)

In terms of cosplay at fan conventions, Dragon*Con is by far the cream of the crop — so much so that I barely pay attention to those who dress up at San Diego Comic-Con and San Francisco’s WonderCon. For instance, the guy decked out as Kratos from God of War stood a good 6 1/2 feet tall and painted every inch of his exposed skin.

Unfortunately for those who prefer the masculine of the sexes, Kratos is not the norm among men. Most male geeks who dress up opt for costumes that don’t celebrate their gender in the same way that their female counterparts do. Still, Geeks of Doom photographer Derek Deweese staked out the entire convention area to find some of the best at this year’s event.

Just as promised, here is the second part of our ladies of Dragon*Con 2010 photo feature. Saturday at the convention seemed twice as packed as the previous day. Seriously, Atlanta’s four largest hotel rooms were filled to capacity with costumed craziness and a handful of extremely puzzled out of towners that came in to watch college football.

On a side note: what you’re not seeing is the large amount of ladies dressed as Merlotte’s Bar & Grill waitresses from HBO’s hit vampire drama True Blood. We haven’t featured any of them in these posts because the costume is pretty basic: white tee shirt with the Merlotte’s logo, a short skirt, and a green apron.

Anyways, below are 20 more ladies we saw at the con that we *don’t* want you to miss. Also, don’t forget to check out part 1 for more photos if you haven’t already done so.
