MrDude

From MrDude Wiki

That's me

In Pokemon Gold, the original one on Gameboy, the person who teaches you how to catch pokemon is named "Dude." I thought to myself, "who names their child 'Dude'?" I immediately restarted the game and named myself "MrDude" as a joke about a character you never interact with again. The name stuck 🤷🏼
