(first, @legomaster1378 or anyone else, feel free to rename this; I’m kinda drawing a blank for the name)
Okay, this just occurred to me: could the Toa Nuva have killed Makuta simply by merging with him? Yes, I specify Nuva, and here’s why: we find out in Legends 5: Inferno, that when Antidermis and Energized Protodermis mix, it causes a reaction that destroys them. The Toa Nuva became Toa Nuva due to Energized Protodermis. If they still had EP in them, say coursing through them, could they have killed Makuta, and likely themselves as well, by getting Makuta to absorb them like he did Nidhiki and Krekka?
Theoretically, that would work only if Toa Nuva still have, or at least have the transforming property of, energized Protodermis inside them, because the Antidermis was destroyed due to the fact that it’s not destined to transform.
But from what I’ve known, EP-transformed objects doesn’t have ability to, in any way, transform others according to their destiny like EP.
