Story progression

Visual language
Symbolism and visual design
Electricity transforms the residue of torture training into speed, agency and a self-authored fighting style.
Frequent changes of clothing make him look like a travelling child rather than a fixed uniformed assassin.
Adaptation notes
Manga versus anime
The 2011 anime uses shifts in lighting, sound and expression to distinguish playful friendship from conditioned threat awareness.
Animated movement makes his economy of motion contrast clearly with Gon's more direct physical commitment.
