Oh my goodness, I aboslutely love this. There are two references here: Portal and Legend of Korra. This is from one of the first episodes of Legend of Korra where Chief Beifong allows Korra to leave her prison cell, but not without leaving a message. And as Korra leaves, she fires a message right back. The genius is replacing the body art with skins from the portal series. Korra has become Chell and Chief Beifong as Glados.
What’s so great about this is because this interplay between the two characters from Legend of Korra resonate fairly well with the characters from Portal. The adorable [yet slightly weird] relationship between Chell and Glados is exactly how Korra treats Chief Beifong. I wish I could credit someone for something so great, but in all honesty, it’s so hard to find sources to unmarked GIFS such as these. If anyone knows please enlighten me.
