Joke characters who became overpowered in fighting games

Several fighting game "joke" characters have proven surprisingly overpowered in certain titles, defying their intended weak status. These characters, often designed for comic relief, have demonstrated significant strength due to unique mechanics, high damage potential, or unpredictable move sets in games like The King of Fighters 15, Marvel vs. Capcom 3, and Tekken 7. Their unexpected power often comes from specific game iterations, making them formidable despite their humorous origins.
