Simisear, as one of the three wise monkeys, is reddish in color and unlike its pre-evolution, Pansear, it carries more hair atop its head, resembling flames. Its arms protrude from shoulders that are covered in fur that looks like clouds. It has a tail resembling smoke with a pointed end. Its belly is mostly yellowish-khaki except for around its waist, where it becomes red again with a triangle design as the border.
Simisear, along with Simisage and Simipour and their respective pre-evolutions are the only Pokémon able to get the abilities solely used by the starter Pokémon. Simisear gains the ability Blaze, previously only attained by Fire-type starters.
Chili's hairstyle slightly resembles that of Simisear's.
