In the Manga
Nizer, the leader of the elite assassination squad Chronos Numbers, specializes in close-range attacks. He wields a pair of tonfas named "Dioskuroi" with exceptional skill. This is evident when he faces a human transformed into a werewolf by Lucifer nanomachines, capable of regenerating any part of its body as long as a single piece remains. Nizer must completely pulverize the werewolf, even its head, to ensure its destruction. Holding a personal vendetta against Creed Diskenth for the death of his former partner, Number X Ash, Nizer is unable to join the attack on Clarken Island due to severe injuries inflicted by Creed's Imagine Blade and a gunshot from Echidna.
In the Anime
In the manga, Nizer sustains serious injuries and cannot participate in the Clarken Island mission. In the anime, however, the scene where Jenos reports the Kerberos mission results to Belze is omitted, leaving Nizer's condition speculative but likely similar to that in the manga. Additionally, the anime depicts the scene where Creed kills Ash and injures Nizer, whereas in the manga, this event is only mentioned.
