Iron Boulder (Japanese: テツノイワオ Tetsunoiwao) is a Rock/Psychic Paradox Pokémon introduced during Generation IX, in The Indigo Disk.

It is not known to evolve into or from any other Pokémon.

It is said to be either a future relative of Terrakion or a counterpart of it from a parallel timeline.

Biology

Iron Boulder is a spherical, bull-like Pokémon coated in a reflective metal. It has a black, rounded forehead adorned with two brown, rotatable, axe-like horns that curve forward. The edge of the horns and the top of the head are colored bright orange blaze. The horns can transform into rounded blade cleaves when attacking. The blades can extend to the width of its head. Its face is grey with digital orange eyes and a short, metal snout. On top of its head are several short spikes. Down its back are two black, spine ridges that join just past its humped shoulders. It has a black circle surrounding its head. There are two orange metal protrusions on its shoulders. The orange blaze bands around its legs are the same color as its horns and forehead. It has grey metal hooves underneath these bands. Its striped underside is also beige. The grey parts of its body have several dark grey lines connecting to different parts. Iron Boulder also has a short, stubby metal tail and can fully rotate its head.

Iron Boulder was first discovered in Area Zero and is said to have originally been an ordinary Terrakion modified by a villainous organization. It stores laser-like energy within its sharp, axe-like horns, which it uses to plow through any obstacle in its path.^[1] This energy is accumulated from the light stored within its head.^[2] It can wield this stored light to rend its opponents. The horns can additionally be imbued with psychic energy while using physical attacks. Iron Boulder's name originates from a mysterious object recorded in Violet Book. While asleep, the orange energy on its head, horns, and feet turns black.

According to AI Turo, Iron Boulder is a future Pokémon related to Terrakion. However, according to a version of Professor Turo that appeared at the Crystal Pool, Iron Boulder is a counterpart of Terrakion from another timeline. Its true origin is unknown. Iron Boulder was brought to the depths of Area Zero by a time machine built by Professor Turo ten years ago. 200 years ago, Heath also encountered Iron Boulder, as seen in the Violet Book, though it is unclear how it arrived there at the time.

Iron Boulder is the only known Pokémon capable of learning the move Mighty Cleave.
