A charming, elderly character with a mix of wisdom and playfulness. He should exude an aura of knowledge, but with a whimsical twist. He should be in his Late 60s with silver hair that's slightly messy, giving off an “eccentric genius” vibe wearing a colourful, mismatched outfit that blends professional with whimsical — think suspenders over a bright-patterned shirt, with a quirky bow tie. He should have a big, warm smile, and perhaps a gentle hunch from age.
