I personally believe that the Attack Titan's ability is some sort of Super Regeneration. This could also tie into his "Berserk" thing he did in Season 1. But time and time again Eren has been shown to be extremely damaged and then somehow get back up again. Even in Season 2, when Eren got mad at the titan which killed his mum, his wounds (specifically shown to be his fingers not fully healed yet) instantly patched up. I don't know if this would tie into his Super Regeneration thing or not, but that's just my theory.
