#1008 Miraidon (ミライドン Miraidon) is a Legendary Pokémon introduced in Generation IX and the cover Pokémon of Pokémon Violet. Its counterpart, Koraidon, is the cover Pokémon of Pokémon Scarlet. It is the Future Paradox Pokémon equivalent of Cyclizar.

Miraidon is a large robotic reptilian Pokémon. Most of its body is violet in color, although its face, claws, abdomen, and tail are gray. Additionally, there are light blue accents on its shoulders and legs, the latter of which resemble jet engines and allow it to float in the air. Its head has a dark purple casque, circular purple cheeks, and black eyes. The eyes have pixelated yellow-cyan pupils. On its neck is a prominent circular growth that is light purple and yellow in color, with light blue streaks. Similar purple-yellow features resembling electricity are visible around its eyes and on its tail.

Miraidon has the ability to change its form in order to facilitate travel. Drive Mode Miraidon can generate energy in its tail and throat and turn them into wheel-like rings, which allow it to accelerate. Aquatic Mode Miraidon is similar in appearance to Drive Mode, and propels itself using both its rings and the jet engines on its legs. Glide Mode Miraidon moves its antennae in order to expand an energy membrane, allowing it to glide through the sky.

Ultimate Mode Miraidon is a large robotic reptilian Pokémon. Most of its body is violet in color, although its face, claws, abdomen, and tail are gray. Additionally, there are light blue accents on its shoulders and legs, the latter of which resemble jet engines when folded and allow it to float in the air. Its head has a dark purple casque, circular purple cheeks, two pairs of antennae, and black eyes. The eyes have a pixelated display; they usually show yellow-cyan pupils, although Miraidon can simulate blinking by changing the display pattern. Inside Miraidon's body is what appears to be purplish-yellow energy, with light blue streaks accenting it. This energy is mostly concentrated on its throat (forming a prominent circular growth), tail, and antennae (which can emit the energy in a manner similar to electricity).

Low-Power Mode Miraidon walks on all fours, with the jet engine-like legs unfolding. The antennae become light sliver along with the throat. The eyes are light blue. The other glowing parts of its body become violet. Miraidon assumes this form either when weakened or not battling. It remains in this form unless it needs to change and adapt.

Miraidon is the game mascot appearing on the box art of Pokémon Violet. It is a Paradox Pokémon, also known as the "Iron Serpent".

Miraidon was first revealed to the public as part of the second trailer for Pokémon Scarlet and Pokémon Violet on June 1, 2022.
