A fully armored Knight

This knight was struggling with a sack full of swords, but that gave us the chance to snap a quick picture of his cool metal armor.

Loki is a girl!

Some of the ladies decide to pay homage to their favorite male characters, but with their own feminine spin. This female version of Thor's nemesis Loki is a fine example.

Captain America

Loki's everywhere, and getting along just fine with Captain America.

HYDRA showgirl

Who says Captain America's the only one who can have showgirls?

Groot and Rocket

Giant Groot and Rocket Raccoon are ready for battle.

Ming

Remember Flash Gordon? Well, this is his archenemy, Ming the Merciless. We first met Ming in the Flash Gordon comic strip from the 1930s.

A mighty family

This whole family got in cosplay mode. From left to right we have Gambit from the X-Men; a female version of Magneto; and the one and only Link from the classic video game The Legend of Zelda.

Darth Vader and a stormtrooper

Star Wars fans also flooded the Convention Center of San Diego. These two really did a cool number with the outfits.

You can check my fun selfie with this pair here on Twitter.

Admrial Akbar

This impressive Admiral Akbar head is made with papier-mâché and it took them three months to finish it.

Evaan Verlaine

I am a "Star Wars" fan (since childhood -- here's what I thought of the trailer for "The Force Awakens") and I love the fact that you discover new characters at Comic-Con. This is Evaan Verlain, "a human pilot who served in the Alliance to Restore the Republic during the Galactic Civil War," according to Wookiepedia.

She's been featuring in the Princess Leia comic book series as the princess' pilot and protector.

Steampunk 'Star Wars'

The idea of steampunk "Star Wars" inspired this magnificent outfit. The cosplayer is Captain Solo Seekerman.

Don't miss our Vine or Instagram video of this outfit because you can see how the mechanic wings operate.

Cartoons come to life!

On the left we see Finn from "Adventure Time" on the Cartoon Network, and on the right we get a bit of anime come to life.

You wanna bite?

Vampires also stop by to feed at San Diego Comic-Con, but her glamour did not work on me because I'm on vervain (thank you, "Vampire Diaries"!).

Vanellope

Vanellope from "Wreck-It Ralph" did not wanna leave her candy race car at the parking lot because someone might snack on it.

Calhoun

Another Wreck-It Ralph appearance: Calhoun.

One of 'The Croods'

Guy from DreamWorks movie "Croods" stop to say hello at Comic-Con.

SkekSil

SkekSil is the Skeksis Chamberlain from the 1982 film "The Dark Crystal."

The cosplayer had a friend to guide him around because it was hard to see and keep an eye on his own tail.

Harley Quinn and Joker

Batman lovers also came down to Comic-Con.

What do you think of these Harley Quinn and Joker cosplayers?

I really like the pose and the makeup -- it's literally crazy.

Harley and Joker

Rockabilly/steampunk interpretations of Harley Quinn and the Joker.

Batman and Joker

Break it up, guys.

Scarecrow

Batman has his hands full with so many of his enemies roaming the show floor.

Ramona Flowers

Ramona Flowers from Scott Pilgrim vs. the World arrived without any of her evil exes.

Doctor Who

The Nerder Mysteries team decided to put their twist on the long-running British TV series "Doctor Who."

Max Headroom?

This costume reminded me of the '80s show "Max Headroom."

It was impressive because he had wired a camera inside the TV box so he was able to look around and give us a fun little dance for the picture.

Van-Dinex and Darkstalkers

On the left we see Me! Me! Me! from the artist Van-DineX and on the right we have Lilith from the 2D video game Darkstalkers.

A singular trio

I snapped a quick one of this three.

On the left we see Chef Flash who makes speedy pizzas, and on the far right we see John Constantine. In the middle, you tell us!

Nortrom the Silencer

This girl made a lady version of Nortrom The Silencer from the video game Dota 2.

Mortal Kombat

Sonya Blade, Scorpion and Sub-Zero.

Scorpio

I had to snap a picture of this cool Scorpio, not only because he looks pretty amazing but also because he was one of my go-to characters when I played Mortal Kombat in the arcade as a teen.

Mass Effect

Commander Shepard, Legion and a friendly-looking  soldier dude.

Beetlejuice

This lady told me that Beetlejuice has been her platonic love since she was little, and this is her homage to him.

Aquafam

Aquaman, Aquawoman and Nightwing.

Spawn

Furiosa

Furiosa, from "Mad Max: Fury Road."

​Aradia Megido

Aradia Megido, from webcomic "Homestuck."

Sadness

Cheer up, Sadness (from the movie Inside Out).

Joy

Joy, from Inside Out, is happy to be here.

Her magical self!

Not everyone cosplays a famous comic character. This lady created her own fantasy self with some inspiration from the Día de los Muertos and the art of bellydance.

Masters of the Universe

He-Man came with some of his fellow Masters, the Sorceress of Castle Grayskull, She-Ra and perhaps Scorpia?

Giselle

This woman told me it took two months to make her dress with help from her grandma.

She surely made a lovely princess Giselle from "Enchanted."

Pinkie Pie

A two-legged version of Pinkie Pie from "My Little Pony."

She bought a regular dress and added some classical elements of Pinkei, including her cutie mark. Plus she made her own ears.
