Enter Necalli (Aztec for Battle) :
First off I love Necalli's design! The tatoo's, his boots, the tattered garb totally add to his character. His brutal game play reminds me of SFIV's Evil Ryu, and when his V trigger is active his hair reminds me of Gill!
We still don't know if Street Fighter V will take place before or after Street Fighter III chronologically but I have a theory that it is before. So a few weeks back there was some discussion floating around on certain FGC sites regarding a brand new character, Eisbahn, that utilized ice elemental attacks, Last night Necalli is revealed and clearly has an affinity to fire.
My current theory is that if we do get a character with an affinity to ice these two characters are the precursors to Gill. Their DNA may be used to create Gill by the Illuminati!

UPDATE: An eagle eyed member of Capcom Unity, Ultimate Boss, spotted something fascinating in Necalli's trailer at the 00:35 mark...
On the right side of the stage there's an entrance to a room inside the mountain! See the cracked rectangular block under the statue???
And as previously mentioned where have we seen those statues before???
Gill's SFIII Second Impact stage!
