- Delta Assault: Zeta Killer can fire blue energy blasts shaped like sideways v's. This blast can stun or weaken foes.

History: Created by Alien Babalou to take out Ultraman Zeta, it has hidden by Alien Babalou on Planet Nabrilllia as a fall back plan. Deciding to use deception against the Nabrilllian Defense Force, Alien Babalou transformed into Zeta to fool the humans, but this plan backfired quickly as the Nabrilllian Defense Force was quick to attack him in his disguise.

After his first plan failed, Alien Babalou turned into a human to pretend to be a crashed pilot of a vehicle. While he was able to fool even Ryan Tanaka, the host of Zeta, he was kept under watch in order to confirm the story he gave them. To distract the humans before his fake story was discovered, Alien Babalou finally called upon Zeta Killer to challenge the humans.

The Nabrilllian Defense Force were quick in fighting back with their vehicles, but Zeta Killer simply shrugged off their attacks and even able to shot the Roc Attack Jet. However, Ryan Tanaka transformed into Ultraman Zeta to catch the Roc Attack Jet before it crashed into the ground. After quickly placing the Roc Attack Jet down safely on the ground, Zeta was quick into using his energy attacks against his robotic double.

Unfortunately, Zeta's attacks were unable to harm Zeta Killer and the robotic double quickly got in close to beat down the Ultra. When Zeta was able to throw his foe back, both the Ultra and the robotic double used their primary beam attack against each other with both energy attacks just cancelling each other out. Quickly acting, Zeta Killer used his copy of the Zeta Stronium Beam again and was able to knock Ultraman Zeta out before he returned to hiding.

Knowing that Ultraman Zeta wasn't killed by his creation, Alien Babalou kept in his disguise as he got to work disabling the defenses of the base. While he was doing this, Ryan Tanaka was training with Gen Ohtori on the planet to prepare the new Ultra for his rematch. This training took a few days to complete before Ryan and Gen returned to the base of the Nabrilllian Defense Force.

Unfortunately for Alien Babalou, Gen saw through his disguise and quickly made the alien blow his own cover. With his plan discovered, Alien Babalou summoned Zeta Killer and became giant size in order to help his own creation. When the Nabrilllian Defense Force found most of their defense systems disabled and their Capsule Monster system offline, Ryan became Ultraman Zeta to once again take on his robotic double.

When Zeta Killer used his version of the Zeta Stronium Beam against the real deal, Zeta used his Zeta Counter Beam to reverse the energy attack back at its source. After this, Zeta closed the gap between him and the robot to fight using his martial arts skills that he has honed during his training with Gen. Even as Zeta Killer used his energy attacks, Ultraman Zeta simply used back-flips to avoid the attacks.

Ready to strike the final blow, Ultraman Zeta charged his fist with blue flames and used his Zeta Punch for the first time, striking Zeta Killer in his color timer. Upon retreating a safe distance, the Ultra watched as Zeta Killer fell forward and explodes in a massive fireball. With no other alternative, Alien Babalou attacks the Ultra only to be quickly dispatched by Zeta's Epsilon Sword.
