Félix Fathom is the cousin of Adrien Agreste, the deuteragonist of Miraculous: Tales of Ladybug and Cat Noir, and the son of English noblewoman Amelie Graham de Vanily and American bilionaire Colt Fathom.
Pierre-Félix Guattari (April 30, 1930 – August 29, 1992) was a French psychotherapist, philosopher, semiologist, and activist. He founded both schizoanalysis and ecosophy, and is best known for his intellectual collaborations with Gilles Deleuze.
The name Felix reminds me of an athlete. As in the boxer Felix Trinidad, and some baseball players too. This name sounds masculine. I would name my kid this.
