Create a finished, extra-wide 21:9 birthday party banner for a six-year-old named Leo. Make it a bold, joyful superhero reveal, with a dynamic low-angle view that makes the lettering power toward the viewer. Keep the background deep midnight navy, clean and atmospheric, with no buildings or room setting. A radiant comic-book burst of red, electric blue and gold fans out from behind the words; sharp speed lines, tiny sparks and a few crackling electric arcs add motion. Sweep a red-and-blue cape shape through the background without covering any text. Add one original gold-edged star shield crest at the far right as a supporting hero emblem, with no letters or numbers on it. Set the exact text, in this hierarchy: small centered eyebrow “SUPERHERO PARTY”; enormous headline “LEO'S”; bold supporting line “6TH BIRTHDAY”; small celebratory tag “POWER UP, HERO!” Keep every line correctly spelled, clearly separated and readable at a distance. Make “LEO'S” the commanding focal point, occupying most of the central width. Use ultra-condensed, heavy display letterforms with tight spacing and distinctive sharp cuts. Construct the lettering as a powered-up chrome insignia: mirror-polished faces with hot specular sweeps, razor-sharp chrome bevels, glowing electric-blue ridge lines and warm red reflections. Cut luminous cyan speed channels through the thick strokes; let blue sparks and thin electric arcs catch on the letter edges. Apply the same chrome hero-emblem treatment to “6TH BIRTHDAY,” scaled down for clear reading; keep the two smaller lines simple and high-contrast. Place the text in a clean stacked hierarchy with generous separation, leaving the shield clear at the right edge. Strong directional key light, saturated red-blue-gold energy, deep dramatic contrast and a festive, triumphant comic-book finish. No extra words, logos, characters, or lettering.
