What is the giant centipede monster from the 2012 footage

An unused concept.

zilla hater is right

yeah, but I honestly hope they use the centipede monster for the sequel. and possible use that little clip he was in too. *SPOILER ALERT* I've heard something about a post credits scene concerning Mothra. maybe if she's in the sequel, the cenitepede monster can be her larva stage?

You mean the scene where Nick Fury approaches Godzilla about the "Avengers Initiative?"

There isn't a scene and there shouldn't be. Edwards went on record stating that he hates end credit scenes and I echo the sentiment. It's okay as a gimic for the Marvel films, but studios really feel compelled to make an audience sit through five mins of credits just to see Ron Perlman lose his shoe in a kaiju?! No, thanks.

Wow sucks, I wanted that to be one of the monsters in the film, I even thought once that it'll be the female Muto but nope nvm then, but hopefully this monster comes up again in the future as a toy, in videogame, or sequel
