Atticus Rhodes (JP: Fubuki Tenjoin) is the missing brother of Alexis Rhodes. He is a member of Obelisk Blue dormitory that suddenly disappeared along with others students. Atticus witnessed Yusuke Fujiwara (One of his close friends) trying to summon Nightshroud (An evil spirit) by using the Nightshroud Mask to obtain immortality. Yusuke gave the Nightshroud Mask to Atticus as a farewell gift. Atticus then got possessed by the mask. Eventually, he and Jaden dueled in a Shadow Game. Atticus lost the duel, then he got released from the control of Nightshroud.
Red-Eyes B. Dragon
Aticcus' deck revolves around his signature monster Red-Eyes B. Dragon. He uses Red-Eyes B. Chick along with Call of the Haunted and Troop dragon to easily summon it. It's also supported by Swing of Memories and Red-Eyes Wyvern to special summon it from the graveyard. By that time, he'll use it as a tribute to summon Red-Eyes Darkness Dragon that has a very high attack due to the dragon monsters on the graveyard. He also interrupts with his opponent's plan by destroying or disabling their spell and traps. He uses cards such as Mystical Space Typhoon and Mirage Dragon. Another strategy of Atticus is to use Inferno Fire Blast and Red-Eyes Burn to inflict devastating damage to his opponent.
Unless they decide to either quit releasing GX characters or start pulling a bunch of new datamined ones like how they seem to be doing with DM, they will eventually be forced to give us Atticus after March. There is no one else currently on the new GX list except for him and another Jaden and Zane (if they aren't event-only characters.)
The day this character appears will be the day Red-Eyes becomes meta again or at least Tier 2
I could see them doing something like Red-Eyes Darkness Dragon, Red-Eyes Retro Dragon, Red-Eyes Fusion, Lei Lei and some existing stuff like Burst Breath, Cave Dragon, Mirage Dragon, Swing of Memories, Red-Eyes Spirit, etc. to fill out his level rewards and drops. Maybe add a few generic dragon cards like Lancer Dragonute or Sniffer Dragon for good measure.
