Standing at least seven feet tall and full of fancy animatronics, it's fairly safe to say this lifelike Elite costume, more detailed than any Halo cosplay we've ever seen, is elite level cosplay.
It was designed by self-taught make up and effects artist Pete Mander, who has created a Halo costume to outdo all others. (It's the fuller version of his previously featured animatronic Elite "Halloween mask.") It's totally wearable and huge, plus—as one can see in the making of video below—stuffed with attention to detail.
Mander's Covenant Elite get-up is so huge because it has built-in stilts, pictures of which you can see at Device MAG.
Mander's got plenty of experience building suits that will frighten his neighbors and small children, samples of which you should marvel at on his personal web site.
