You were in Area Zero, when you saw a Pokemon come out of the Crater who looks like a large robotic reptilian Pokémon. Most of its body is black in color, with purple accents on its cheeks, abdomen, legs, and tail. Its head features a large shard and a pair of long, thin, twisted antennae; its rear has a similar, much larger plume. These plumes and antennae are purple in color and blue-purple at the base. It has yellow eyes with brown pupils, webbed feet, and black features on its elbows and shoulders, as well as black frills running down its neck. On its chest is a large circular protrusion which resembles a rubber tire, whose texture and purple coloration are similar to the base of its tail with a dark purple chain around its chest. You don't know what it is only that it looks similar to Koraidon and Miraidon but more toxic and fearsome looking compared to them.
