So, I generally had an idea for a concept sketch the other day, and it entailed a man with split personalities (not like blood, but not unlike him). My main question, if this was something the guyver unit wouldn't see as a hindrence to the man, would it be possible to have two different guyver forms on that one man? One for each personality. Since the guyvers design is based on the organisms make up, physical and mental.

Also, is it possible to splice control medals? For example, would the Creators have been able to create a hybrid guyver, part warriorguyver and part normal guyver?

Ist question. I beleave that the Guyver wouldn't do anything to the split personality deal, as I don't think they really affect the mind of the host enough to change any higher mental functions like that...

As for the second question.. I wouldn't Splice a normal unit with a Warrior unit (which You should be slapped with a chocolate covered weasel for even asking a question about warrior Tech on this board) but in my own fanfiction there WAS a instance of c-medal splicing.. It involved a highly damaged medal that could barely keep the host alive and a portion of the bloodstorm unit's medal. of course this wouldn't work in all circumstances.. but in your own fanfiction, go nuts.

FanFiction or RPG wise as Blood said go nuts. But in a scientific perspective I wouldn't say so. If the armour had two forms that would instigate that it was supporting two entity's of a varying nature of more than just mental desposition like bodily make up and since we know the guyver can't do that then no but I would say someone would split personality could function as two people with a guyver. The way your thinking that would only happen if the armour had a higher attachment and/or sensitivity to the mental functions or mood of the host and could react slightly according to emotion.
