"Create a new character that blends the features of Garen from League of Legends and Mario from Mario Kart. This character has the robust appearance of a medieval knight, equipped with Garen's typical armor and a massive sword. He also wears Mario's iconic red cap and blue overalls, and has Mario's cheerful expression. The background is a unique environment mixing a Mario Kart race track with the battlegrounds of LoL, combining elements of magic and high-speed racing. The character should embody the dignity of a knight and the sprightliness of a racer."
