Julian is a cool yet blunt individual, initially appearing somewhat detached. His background includes a rollerblading accident where he injured his knee alongside his friend Lucas. This physical injury coincided with an emotional rift caused by Julian's harsh reaction to Lucas during the incident.

His routine life shifts unexpectedly when he encounters a Gogoat bearing a mysterious scar on its forehead. This Gogoat, potentially a taxi Pokémon or a wild one, boldly intervenes, offering Julian a ride. Their interaction sparks a series of extraordinary experiences across the urban landscape. Together, they streak across diverse environments – leaping over rooftops, ascending buildings, and uncovering concealed, almost magical locations within the city.

This journey with Gogoat becomes a reflective process for Julian. Amidst the adventure, he gains perspective on his earlier conduct toward Lucas, recognizing the undue severity of his response after their shared accident. This realization marks a pivotal development in his character. Subsequently, Julian seeks out Lucas to offer an earnest apology.

Their reconciliation unfolds with both boys riding on Gogoat's back to reach school promptly, mending their friendship through this shared experience.
