Numel is a yellow, quadrupedal Pokémon that resembles a Dromedary camel with a volcano-like hump on its back. The hump is green at the very top and fades out into yellow with small green spots. It contains magma of almost 2,200 °F (1,200 °C). A female will have a bigger hump than a male. It has bangs on top of its head, sleepy eyes with brown circles around them, and short, stubby legs.
Numel is a very strong Pokémon, having served humans for many years with its ability to carry heavy loads up to 220 lbs. (100 kg). However, it slows down when wet and cannot stand when it is hungry. Due to its dull wits, it does not notice when it has been hit. Numel lives on volcanic mountains.
Numel, the Numb Pokémon. Numel is so complacent that it does not even notice when it is stuck. This Pokémon's body is filled with hot magma, which, when cooled in water, further slows its movement. Numel is also unable to bear hunger.
Numel's evolutionary line may be considered a counterpart of Carvanha's evolutionary line. Both of them are dual-type Pokémon, both lines have identical base stat totals per evolutionary stage, both of their final evolutions are used by Team Magma Leader Maxie and Team Aqua Leader Archie, respectively, and both of their final evolutions can Mega Evolve.
Numel appears to be based on a stylized dromedary camel with its single hump fashioned into a dormant volcano. However, Numel's barrel-shaped body and simplified extremities may also draw inspiration from a mule or donkey-shaped piñata.
