[@Sho Minazuki] Uh. I was aiming for something along the lines of the Grace and Glory enemies from Bayonetta, which would be two entities which, though they don't copy one another's attacks Ice Climbers style the way you described, definitely work in concert with one another in battle to kill their targets, and so far as I'm aware are never seen apart in-game unless one of the pair has actually died shortly beforehand... how closely tied are we talking? Aside from always fighting together, do they actually have to [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/HiveMind]share a mind[/url], or be so similar that they might as well be sharing one mind? Would they need to [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/Synchronization]share damage between themselves?[/url] Would a form of [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/TwinTelepathy]twin telepathy[/url] be enough for them to count as one character, when combined with the whole "they fight as one entity" concept? A touch more elaboration on that topic might help me establish whether to stick with the concept, or whether I should perhaps move on to something less difficult to incorporate as far as limitations on number of characters is concerned.
