Aaron Mikaelson (IEs)

Aaron Mikaelson was the chronologically oldest son Mikael and Esther in the Mikaelson family and was believed to be dead to all but Klaus and Esther in the Immortal Eternal series, Aaron wasn't killed by the plague but was instead trapped in stasis quite similar to how Esther had been before she had been awakened by Bonnie and Abby, Aaron was said to be a Delta-type Hybrid due to his mother's experiments in attempting to help Aaron fight off the plague that still inhabited his body.

Due to being kept in Stasis he hasn't changed a day since his parents abandoned their homeland to travel to the new world and he was kept secretly in an underground cave, one of the experiments that Esther did to her son was to blend his Sorcerer genes with those of a Werewolf and following his transformation hope that the disease was combated, but the disease had infiltrated far too deeply even before the process and remained trapped within the sliced genetic code, it wasn't until Esther cast the Originals spell did the disease dissipate however in doing so Esther had unintentionally created a unique Hybrid: a Delta-type Hybrid.

After becoming this Hybrid he made his first kill however he was betrayed when his mother bound Aaron to Klaus briefly and used him as the medium to create the Hybrid Curse, Esther then trapped Aaron in his stone Coffin which the enchantment upon it effected him without the Werewolf aspect to help defend against it, Klaus sought his stone coffin but would not find it but instead it would be found by the most unlikely person shortly after the Hybrid Curse was broken.

Aaron is a member of the Mikaelson Family and he is also the "Submissive Mate" to Zachary Udolf.
