Mumu/Personality and characteristics

Mumu was noted in his debut appearance for being less coordinated, swift, and graceful compared to the rest of Ruby's team at the time, and habitually left a trail of mucus from his nose. Despite this, Mumu quickly won Ruby over with his resourcefulness and ability to use his fin's enhanced senses to detect enemies. As Ruby's Pokémon Contest representative for the Toughness category, Mumu exhibits great fortitude and power in contests and battle, becoming Ruby's main powerhouse as the chapter developed. After evolving, many of Mumu's clumsier traits as a seem to have faded.
