دیلاندایو الباتو

A mentally unstable pyromaniac with a bizarre and shocking past, Dilandau is the tactically ineffective commander of the Zaibach empire's elite Dragonslayer's unit. Diandau takes no prisoners, and burns towns to the ground with little provocation. After being wounded in a sword-duel with Van Fanel, Dilandau becomes fixated upon him, and places vengeance over all other objectives (with as much fire and collateral damage as possible, of course).

[Spoiler: It's revealed later in the series that Dilandau is the result of Zaibach's experimentation on Allen Schezar's sister, Celena. When Celena was abducted by Zaibach, they used her to test their "fate altering machine", which changed her fate to become Dilandau. After having a mental breakdown, the fate tampering on Dilandau's body begins to come undone, and he's sent back to Zaibach to be fixed. After Allen discovers the truth about Dilandau, he's able to convince Dliandau to stop resisting his true fate as Allen's sister, and he permanently becomes Celena.]

In the 1994 manga, Dilandu has a drasticly different design and character. He has dark skin and black curly hair that grows longer over the course of the manga. In the manga he is one of the most fearful knights of Zaibach, and he destroys the kingdom of Fanelia and kidnapps Van's mother Escalina. He keeps her alive, but is ordered by Donkirk to kill her, at which point he defects from Zaibach and runs away with Escalina as his captive. From there he pretends to work together with the resistance against Zaibach, but he has grander plans in the works.
