I saw some new characters are leaked, Zexal is neer to debut....All that is OK with me but I would like to see some new character from original Yu-Gi-Oh! Like Aknadin,Karim, Mahad, Isis, Shadi, Dartz....Also I think that GX should have more female characters like Camula and Tania...And the last thing...Zexal is neer, and somehow I think Cathy and Anna should be better choise than Tori for begining...I even Astral wouldn chouse before Quatro, Nistro, Dextra....
Officially, we just know that Zexal might come soon since there is a code line with Zexal written on it. No characters have been announced. The Zexal characters mentioned in the Leaked News page are presented as "potential characters".
Red-Eyes Darkness Metal Dragon is more like Magma/Storm/Chaos Neos or Dark Magician of Chaos, who are much stronger than regular Neos or Dark Magician, but they are never referred as the ace.
We have Carly and Dark signer Carly...In original Yu-Gi-Oh! we have Seto from time of Pharaoh and Yugi is Pharaoh in that timeline...So from my point of view, they should be also member of Yu-gi-oh world/game. Same thing is with Isis/Ishizu
Carly and DS Carly both are modern people who play the card game.
It makes no sense for Seto and Isis (the pharaoh guardians) to be in Duel Links. Nevermind the technology, they never even do something remotely similar to the card game. Duels in their time are more like Stand battles.
