now that aporia is coming to dl, this means konami is finished with 5ds world. since aporia was the final boss and in the finale yusei beats him and aporia crashes into the ocean and dies. with dm, gx and 5ds finished, konami will focus on adding only zexal and arc v chars moving forward
All those characters are irrelevants, like imagine literally wasting a event to release something like "fake kaiba" lol.
Also the final boss of 5ds was Z-one not Aporia, and even we still have chance to get Sherry since she become part of the Ark Cradle villains temporally.
What about the other bosses/characters from gx and 5ds, don't they deserve some consideration? I mean take Red-Eyes Darkness Dragon, you got Alexis Rhodes Brother. 5ds, you got the other two Meklords. They only added Primo and Aporia, the other two deserve to be in the game also. I mean if Duke Devlin, Lumis & Umbra, and Arkana...why not the others?
Bosses already being in the game doesn't mean much. Most bosses these days are box cards rather than drops/level rewards anyway, and even back in the day, we had the odd character that had an existing card as a boss, like the Paradox Brothers.
In fact, Z-One was the final boss, though I think it would be weird to see him as a playable character.
There are others that could be released in 5d's world, like Sherry LeBlanc and other Tournament participants (Team Ragnarok and the unicorn guys, for example). And a final special mention [spoiler] to Paradox, which is related to 5d's plot according to a few dialog lines.
What do you mean by a playable Z-One being weird exactly? All Z-One does uniquely is duel in his floating chair and use mechanical hands to play Timelords.
