This cosplayer opted for a Game of Thrones getup, pulling out all the stops on July 23 with a head-turning ensemble consisting of a floor-length dress, crown and custom-made throne.

Margot Robbie, is that you? Sporting dip-dyed pigtails and a "Daddy's Lil Monster" T-shirt on July 21, this fan's ensemble looked almost identical to the one the Australian actress sports in Suicide Squad.

One cosplayer went all out for Comic-Con on July 22, arriving to the convention in full-blown Dia de Los Muertos attire, complete with a super-sized red sombrero and intricate makeup.

In honor of Sharknando: The 4th Awakens premiering on July 31, Trolli and Syfy teamed up to have a weirdly awesome costume contest in the streets of San Diego. Their "Pa-Trolli" staff, however, knocked it out of the park even more with their Vegas-inspired shark costumes. Tune in on Saturday to see the winner announced live.

This girl is definitely a Sanrio fan! During the Comic-Con International preview night on July 20, this super fan hung out at the Sanrio booth and showed off her love of the characters on her skirt, jacket, purse, shoes and even her head.

Surfs up, dude! On July 21, this cosplayer took his costume to the next level by actually spray painting his whole body silver to resemble Marvel's Silver Surfer and only wearing a Speedo underneath. He completed his look by carrying a silver surfboard throughout the convention.

This land mermaid channeled her inner sea creature while hanging out inside SDCC's convention center on July 21. She donned scale-printed leggings that matched her sprayed-on scale body art and netting that adorned her trident and boots.

Mommy's little monster is right! Margot Robbie would be impressed by this guy's accurate -- and very detailed -- Harley Quinn costume. He even painted his face white and rocked pigtails and booty shorts worthy of being in Suicide Squad.

These two guys went all out with their ode to Mad Max: Fury Road on July 21 in San Diego. In addition to putting silver makeup all over their faces, they created fake weapons (with a water bottle) and steering wheel, which had a creepy doll head in the middle of it.

Friends and enemies unite at Comic-Con International! On July 21 these three fans posed together, even though Wario (on the left) is enemies of Mario and his brother, Luigi, in the games.

Supergirls stick together. These two ladies took a break from the SDCC festivities on July 21 to pose together for an X-Men costume photo. One cosplayer rocked all silver with blonde locks and blue eye and lip makeup to resemble Emma Frost, while the other wore a red wig and a red and gold, full-body costume like Firestar.

The Force is strong with these costumes. Three cosplayers posed together inside SDCC on July 21 dressed head-to-toe in their best Star Wars: The Force Awakens garb.

These two cosplayers brought sexy back to Star Wars with their movie-themed costumes. One rocked a R2-D2 bikini with sheer skirt, while the other opted for a BB-8 inspired corset top and silver pants on July 21.

Sharknando's Vegas-themed costume contest wouldn't be complete without an Elvis walking around. The legendary singer was brought to life with the help of a wide-legged pantsuit and a shark coming out of this fan's chest and back on July 21.

Who you gonna call? It looks like Ghostbusters has found its fifth female ghost fighter in this SDCC fan, who went all out with her costume, even adding a fake ghost blaster made out of foil and paper on July 21.
