Here are a couple of ideas of some old characters, playable or not that I would like to see in Guilty Gear Xrd as returning;
Johnny
Dizzy
Jam
Zappa
Baiken
Anji
Izuna
Dr. Paradigm
Bridget
Baldias
That Man/The Gear Maker
Several of them all having been in Guilty Gear Vastedge XT, a pachinko/slot machine visual novel game set 1 year after Guilty Gear 2 and a year before the start of Xrd.
All the characters I mentioned also had designs for them, and Baldias also is part of the Senate in the game's backstory. :) Here're their designs, courtesy of the Guilty Gear Wiki. :)
