If that frame is of any indication, Sekhmet also has yellow eyes.
Big Band's sprite is just very slightly taller than Double.
More like Zelda/Sheik, two different modes you can switch into and around with. Gen SF4? (I have no idea about Smash but I think that's what Zelda does?)
(yes, that is correct, that is how Zelda works)
Well, yes, but the comparison to explain how Eliza works still stands as that is how it has been. nonetheless, different topic for a different thread :P
We can only speculate but most things point (chiefly Mariel's comment of her being as taxing as two characters, workwise) to her being a full dual stance character, like the examples provided by IsaVulpes. The current headscratchers are if Sekhmet will be timed or unlimited; pre-requisite dependent or immediately accessible?
