Lost S5 Finale

[Gogan]

The general consensus, I think, is that the status is of the egyptian god Sobek. Not only do the pictures of Sobek look pretty spot on with what we see in the show, but the legend behind him seems to fit as well:

The god Sobek, which was depicted as a crocodile or a man with the head of a crocodile. In some Egyptian creation myths, it was Sobek who first came out of the waters of chaos to create the world. As a creator god, he was occasionally linked with the sun god Ra.
...
Sobek's ambiguous nature led some Egyptians to believe that he was a repairer of evil that had been done, rather than a force for good in itself, for example, going to Duat to restore damage done to the dead as a result of their form of death. He was also said to call on suitable gods and goddesses required for protecting people in situation, effectively having a more distant role, nudging things along, rather than taking an active part.
...
He was also shown with an ankh, representing his ability to undo evil and so cure ills.
