Here's a new picture of the Shigyo with a description! If anybody can translate the text, that would be a great help!
I know they both look like water monsters are are similar, but either the monster changes its appearance or they aren't the same monster, or its look changed since the PAX build. There are mechanisms on the monsters hair not present in the new shot, the body is completely different (the new monsters body looks more like a jellyfish or something while the old one has a body similar to Lara...)
Actually, typing that out, what if the monster can change its form? Like what if its body is naturally a gelentous blob like we see in the new art that makes it look like a Jellyfish, and maybe it imitates other things? Because the body in the first shot definitely looks like Lara's.
I think its the same monster as there is always water surrounding the beast whenever it moves and such, but I was thinking maybe it can change its bodies form.
