Look! It's Princess Groot, and she's a Christmas tree! Montreal Comiccon is so popular they do it twice a year, once in July and again in December for their Holiday Edition. The Holiday Edition was this weekend, to give cosplayers a chance to for some Christmas decorating, or set up photo opportunities in the bitter cold outside. Seriously, if you think you're cold, look up the weather in Quebec.
Not everyone was dressed in holiday style, but the cosplayers went all out for detail and authenticity. Above is Altaïr from the game Assassin's Creed, and below is the Monkey King from many ancient Chinese legends.
Geeks Are Sexy was there to document the festivities, as always. Their gallery of cosplayers is a little different- there are more pictures than usual, and each character is identified in the main post when possible. You can click on any image to bring up a full-size version.
