Metapod is an insect Pokémon that resembles a green chrysalis. Its body is crescent-shaped, with several segments making up the lower point. It has two heavy-lidded eyes on the sides of its shell, while the front of its shell feature geometrically shaped portions and projections, and the back has three pointed protrusions; two veering towards the sides, and one in the middle. In certain angles, the back of a Metapod's shell resembles a face alongside the eyes on the sides, with one of the protrusions resembling a sharply pointed nose, and the tail resembling a sharply pointed chin.

Metapod's soft body is protected by a hard outer shell as it undergoes metamorphosis. While this shell is said to be as hard as steel, a sudden, powerful impact could cause its liquid innards to pop out, leaving it completely exposed. Metapod generally remains motionless, rebuilding its cells for Evolution. If an enemy discovers Metapod, it cannot do anything other than harden its outer shell. Metapod lives in temperate forests and jungles, often in groups. Pikipek is a natural predator of Metapod. As shown in Pokémon Sleep, Metapod is known to sleep while using the move Harden constantly to protect its innards. It stays still while sleeping to avoid getting attacked by foes.
