「NIGHT GUARDIAN」は FontVibe AI で作成したスーパーヒーローの文字エフェクトです。クロームの縁を持つ斜体の赤と青の3D大文字。後ろには赤いマントがなびき、稲妻の絡む白い閃光から飛び出します。

Heroic authority lettering — letters as identity marks of power: bold, monumental, commanding. Strong single key light defines high-contrast form. Letters feel physically constructed — cast, forged, embossed, or built — not printed. Background: deep dark field (navy, charcoal, or black) maximizes letter contrast and gravitas. Hard cast shadows anchor letters as solid objects. Composition: letters fill frame as absolute subject. Cinematic hero title card — deep dark dramatic landscape, storm-lit sky behind, city lights glowing at the horizon. "NIGHT GUARDIAN" in massive ultra-condensed chrome badge lettering centered across the wide frame, filling 72% of frame width — the title of a hero origin story. Single powerful overhead white spotlight. Electric-blue ambient fill. Hard shadows below the letters on the dark ground plane. Anamorphic lens flare from the key light, cold horizontal streak. MCU opening title card atmosphere — 16:9 cinematic.
