Rauzaruku ラウザルク Assist User Zatch Bell Lightning Strengthening Description Rauzaruku (ラウザルク), also known as Rauzaruk in the English localization, is Zatch's sixth spell, obtained during their battle with Kido and Dr. Riddles. It summons a multicolored bolt of lightning that strikes Zatch, enveloping him in a vivid rainbow aura. This energy surge drastically amplifies his physical capabilities—speed, strength, and endurance—for approximately thirty seconds. While under the effects of Rauzaruku, Zatch’s spellbook temporarily blocks the use of all other spells, forcing him to rely solely on his empowered body. Despite the immense output, Zatch remains conscious throughout its duration, allowing full combat control. The aura fades suddenly, leaving the user fatigued, emphasizing the spell’s nature as a high-risk, high-reward enhancement.

Rauzaruku ラウザルク Assist User Zeno Bell Lightning Strengthening Description Rauzaruku (ラウザルク) also appears in several video games as a support spell used by Zeno. When activated, Zeno’s body becomes surrounded by a sharp blue-white aura of electricity, dramatically heightening his physical power. Unlike Zatch’s version, Zeno’s manifestation favors precision and acceleration over raw strength, enabling lightning-fast strikes and counterattacks. In gameplay, Rauzaruku often grants Zeno an electrically charged punch or aerial launch attack, visually echoing his control-oriented fighting style. Though non-canon to the manga, this adaptation reinforces the spell’s thematic link between lightning and physical amplification shared by both brothers.

Trivia

• In the video games and trading cards, Rauzaruku is colored gold instead of the rainbow-colored version seen in the anime when used by Zatch, and bluish white when used by Zeno.
• It is shown to be physically taxing, as the user is momentarily immobilized when the effects of the spell wear off.
