Launch is from the Japanese manga — modern formation. Launch is a character in the original Dragon Ball (1984-1995) by Akira Toriyama (1955-2024). The Dragon Ball manga has sold over 350 million copies worldwide. Lives at Master Roshi's Kame House.
Launch does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.

In Pythagorean numerology the letters of Launch reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
