>>7843584I suppose the Adaptive Armor suits can't merge together since they're not really part of the Toa, so without the AA yes, Tahu & co and their relative Kaita would look exactly the same as they did in 2002-2003-2006-2007.
Kind of short-sighted on Artakha's part, but then again I feel this one of those very minor Rowling-esque pieces of trivia you won't have any trouble ignoring, if a AA Kaita is what you want to build.
