He has spiky crimson-red hair with a long ponytail, as well as red eyes. Jabberwock has stubble on his chin and several scars across his face, most prominently a large traversal one across his right eye down to his left cheek.

He dresses like other Demons Behemoth's 34 Pillar Division, but more luxuriously due to being their leader. Like other Demons, he also has fish-like ears.

Personality
His attitude is haughty and he immediately dismisses Oga as an unworthy opponent on first meeting him. Jabberwock then proceeds to have his pet dragon Sodom (described as a "Grand Bahamut") kidnap Hilda by swallowing her alive. He seems to respect Saotome and wishes to face him in battle, but is more reluctant than his father to be under the leadership of Lord En's, to whom he refers as a stupid kid. His recklessness has earned him the nickname "Crazy Dragon". His nasty temper got him expelled from the squad at a point, but he was readmitted by his father. He like Oga and Tojo, is battle crazy and finds battle to be very fun. With him happily looking forward to battling Oga, who he sees as a worthy opponent. He is not above complimenting his opponents during a battle.

History
In the past he was removed from Behemoth's 34 Pillar Division due to his temperament, earning him the name "Crazy Dragon", however Jabberwock was reinstated by his father as the General of the army due his father's wishing Jabberwock to become his successor (this however was not mentioned to the other members of the army till after his re-instatement). It's also notable that he used to be a childhood aquantance of Laymia.

Akumano Academy Arc
His was first revealed in the manga was when Oga & Hilda confronted Behemoth on the roof of St. Ishiyama after the latters confrontation with Zenjūrō Saotome, Genma Isurugi & Ittōsai Kunieda. Believing Behemoth to be the leader of the army prepared to kill him, Oga confronted the aged man who protested he was no longer incharge. At this moment Jabberwock appeared, wishing to leave to attend to "that stupid kid ". When Hilda defensively raised her blade, Jabberwock summoned Sodom to kidnap her in his mouth and flew away on the bahamut's back. When Oga jumped on the beasts back to challenge him, Jabberwock made short work of the delinquent, easily dismissing Oga's strongest attacks (he however had managed to free Hilda temporarily). Once they retrived the escaped wetnurse Jabberwock and Behemoth made their way to Akuma Academy.

He is later seen at the academy's headmaster office with Behemoth and the captive Hilda, displeased he has to partake in En's "game". He leaves the office where he meets with his old acquaintance Laymia. After a brief conversation about their past, he reveals his position as her General stating "it's not the same as when we were kids" and leaves. He reappears during Oga's rush in the school, after his win in Quetzalcoatl's game. He picks a fight with Tojo and Oga, and he manages to take on the two of them, being able to fully take a German Suplex from Tojo and a Full Power Zebul Blast from Oga, and to deal a great amount of damage to both. He also resist to Oga's Full Synchro form with Beel. Anyway, when he is absolutely certain of winning the fight, Oga stands up. It's not exactly known the process but Beel's maturation is accelerated with the use of Black Techs learned by Oga and therefore the ability of the Demon Lord's Contractor power up too. Jabberowock can't stand Oga's blows and faints after a destructive punch of Oga.

Powers & Abilities
As leader of Behemoth's 34 Pillar Division, it can be assumed Jabberwock is very powerful. This is demonstrated by his fear induced control over the grand bahamut Sodom. In battle he has been seen to easily take several of Oga's Zebul Emblem hits even after entering super milk time as well as breaking Oga's leg. He has even made Saotome drop a sweat. He has a great physical resistance since he easily takes some seriously strong Oga and Tojou's blows being still able to counter and defeat those two. He also possesses a huge Demonic Power since even humans like Nene and Natsume notice it. He is also able to shoot a Demonic Aura cannon similar to Naga's like when he tried to kill Hilda while she was crucifixed.

Sodom
Jabberwock commands the Grand Bahamut with fear, acting as a mode of transport and a pet to the General.

Laymia
They were childhood friends but they now show hostility towards each other.

Oga Tatsumi
During his first encouter with Oga, he looked down on him believing that he was not such of a worthy opponent. After Oga attempts to rescue Hilda, the two clash on Sodom's back where Jabberwock easily defeats Oga. He has taken an interest in Oga's strength with the use of Super Milk Time and wishes to enjoy an all out battle with him.
