In the current game, there are references and parodies to other games and pop culture.
Here is Ms. Lara Croft from tomb raider
However, what is probably way more interesting is that this is a censored/revised version. Originally, the guys at 3drealms had made their own custom Lara sprite. It's much more anime, and she has a nice cloth gag!
The devs who work on TR saw this and gave us the 1st sprite instead. In the actual game she's like a gif that moves a little, but nothing crazy.
Still a cool find I had to share!
