Kallavan/Appearance and Personality

Appearance
Kallavan has fair skin, blue eyes, and initially blonde hair. His blonde hair was styled as a mohawk. Kallavan is very tall and large built or muscular.

Fashion and Outfits
In his initial design, he wears a long dark blue robe with his own insignia on it and chains around his waist.

After the time skip of the Battle of The Last Station, in The Wall of Peaceful Coexistence (Arc) Kallavan grew out his hair and he is shown to be wearing a much more casual outfit, blue jacket, blue caps, and short pants than his previous stylish outfit as Corps Commander.

During the Battle of The Nest, Kallavan was seen to wear a dark navy military uniform which consisted of beret hat with Zahard's logo, big coat or jacket with military ranks insignia on both shoulders, and long pants. This is most likely a special outfit that was prepared by Zahard's Army to prevent the strong floating effect caused by The Frozen Waterfall within The Nest.

He uses two coats to hide the bound which sealed his left arm. The coat is attached by a pin to the shoulder so that it won't fall off when he fights.

Personality
He is said to be very militaristic among Zahard's Army. SIU said he seems to have an overflowing amount of bluffing power which is a quality for a boss. He appears to be a Zahard fanatic, which he believes he can make his dream come true, and also believes Zahard is omnipotent and omniscient as the one true King of the Tower.

Kallavan is a man who follows his orders from the army and will put his personal issues aside no matter what. He sees killing Baam only as a mission and would not do so otherwise as it was seen during the battle and the Wall of Peaceful Coexistence and The Nest when his main mission was not about killing the Irregular. He also shows a sense of honour, as he was genuinely disgusted by the Wall's inhabitants disregard of Dowon after she had risked her life to fight for their ancestors and taught them a lesson violently for it and did his best to uphold the end of his bargain with Khane to not damage the Wall and apologized for not being able to uphold it against White's Spinel.

Kallavan is shown to care deeply for his subordinates, who are all so blindly loyal to him it was noted they are more loyal to him than they are to Zahard and henceforth why they were deemed unfit to be in Zahard's Army and replaced by stronger and more loyal soldiers by Lyborick. He was strongly against Lyborick's plans of sacrificing his men to destroy the Cage by blowing up the flagship and though he agreed, he promised to kill Lyborick if the plan fails and his men died for nothing. When the flagship finally exploded, killing many of Kallavan's men, he felt sufficient grief to stop fighting White, remembering the memories he had with his followers, and with Baam rendering their sacrifice null by teleporting his enemies to safety, Kallavan stayed true to his intention to kill Lyborick for sacrificing his followers for nothing, even temporarily alligning with Baam to take back his position as the 4th Army Corps Commander and promising ceasefire until he has saved Jinsung.
