Xu Mu

Biodata

Power Progression

Background and History

Xu Mu arrives in a world where humans and Pokémon coexist, carrying the memories of a sixteen-year-old whose father disappeared years earlier. His father’s coming-of-age gift contains Greninja. Contact with the Pokémon activates Xu Mu’s Pokémon Check-In System, whose battle-related tasks immediately conflict with his plan to avoid the dangerous Trainer profession 1.

Xu Mu asks to leave school and travel, but its leaders test his ability in a battle against discipline director Yu Hailong. After Greninja wins, they offer Xu Mu exam-free trainer registration, a year off, and a Pokémon from Principal Xiao Tianyang. Xu Mu accepts and chooses a seemingly idle Charmander, only to discover that it is already exceptionally strong 3 4 5 6.

At the Flame City Rookie League, Greninja and Charmander pursue training and system tasks even while Xu Mu sleeps. He wins the championship, sells a rare Charmander egg for thirty million League coins, and gives five million to his mother before setting out to travel 8 9 17 18.

In the Viridian Wilds, Xu Mu rescues Cynthia and invites her to travel with him. He later challenges Venerable Dongfeng to defend Entei from a group attack. Entei entrusts Xu Mu with an egg, making him a target for the assembled powerhouses; Xu Mu refuses to surrender it, and his long-missing father arrives to save him. The egg subsequently hatches into Arceus 20 24 26 30 31 32 34.

Personality

Xu Mu wants enough strength to stay safe, not a career devoted to becoming the strongest Trainer. He distrusts the system’s missions and repeatedly refuses to train his Pokémon himself, even as their ambitions pull him into stronger competitions 2 36 47 48.

He is quick-witted and openly defiant when threatened, but attentive to his mother and Pokémon. His pursuit of Cynthia is playful and sometimes contrived; despite his bravado, he becomes flustered when speaking plainly about his feelings 18 23 34 40 44.
