OK, since Cybor has MORE of his father's (Lyon; the Elemental Demon Echidna) DNA than his mom (Luna; the Echidna [angel]), THIS will happen to him VERY soon.
OK, Elemental Demons are one of the most dangerous demons in the world and also very hot tempered... OBVIOUS!!! XD The elemental demons has two forms; their true demonic selves AND their mobian selves. When they reach a certain "age", their bodies will start having a serious, painful transformation. their syptoms are puking blood, sudden change of eye color, fur and skin grows dark, sudden chills and the deepening of the voice. Once they FIRST turn into their true forms, YOU MUST STAY AWAY FROM THEM FOR THREE WEEKS!!!! ....UNLESS you are their mate.
They WILL not hessitate to harm you....or worse.
what will ALSO speed up the prosess if YOU killed their mate.... which is a TOTALLY BAD IDEA!!!!
