ok this is a picture i had planed before i joined da but coz of lak of an origanl story i never go to this part.
for those who do not know when someone becomes a heartless by giving in to the darkness in their heart, the person leaves an empty shell that takes its own form. that shell is called a nobody.
this info is from kingdom hearts BTW.
the nobody has all the memory's of the heartless it was born from. in this case Zanders memorys.
even though Zander became a heartless his feelings for his friends made him a normal pokemon again. but in-complete.
Zardenx is half Zander and half nothing. so he has Zanders aura. if the two came back into one person then Zardenx would disappear and Zander will be whole again.
of corse Zardenx wants to be himself free from that stuff. witch is why hes got to kill Zander. ^^ oh wait. thats not good.
besides that he gets along with anyone. he like to make friends. and doesn't argue unless he has too.
Zardenx has brown eyes and a red collar. also his hair is a bit different from Zanders.
