Felix is an eccentric german mad scientist, characterized by his wild, blonde spiky hair that seems to defy gravity. His pale skin contrasts sharply with his slightly yellowed teeth, one of which is conspicuously chipped, giving him a somewhat disheveled appearance. His brown eyes are particularly striking, with the right one exhibiting polycoria, adding an unsettling uniqueness to his gaze. A prominent scar runs through his right eyebrow, carving a jagged path across his eye and down his cheek, hinting at a life filled with reckless experiments and adventures.

He is often seen wearing a crisp white lab coat that flares out with an air of chaotic authority, over a casual blue t-shirt that softens his intense look. His dark brown pants are practical yet stylish, and his black dress shoes, polished to a shine, suggest that despite his outlandish demeanor, he still maintains some semblance of professionalism. Overall, Felix presents a striking figure, blending elements of genius and madness in both his appearance and attire.

Secretly, he has black, slippery tendrils that protrude from his back and hide within the sleeves of his lab coat, going unnoticed.
