Zeta Gundam's trademark finishing move, first seen used in the final episode of its eponymous show and commonly featured as the unit's strongest attack in Super Robot Wars.
In Waverider Mode, the Zeta Gundam does a high-speed ramming maneuver onto its target, which is rendered unable to move by the former's Biosensor System. The Biosensor also uses the spirits of the deceased (usually those of who have a relationship with the pilot such as friends or even enemies) to boost the power of this attack.
Zeta's pilot Kamille Bidan uses this move to kill Paptimus Scirocco, who was prior to this, untouchable in combat thanks to his Newtype powers, piloting skill and the speed and tough armor of his The Omobile suit. Despite decisively winning using this move, it became Kamille's undoing due to Scirocco being able to hit him with a mind-crippling psychic attack at close proximity with his dying breath, that turned him insane afterwards (and becoming a vegetable at the start of Gundam ZZ).
This tag is also used for the exaggerated facial expression Scirocco makes during the scene.
