Magearna

An artificial Pokemon created as a princess's nursemaid centuries ago. As such she is patient and caring, with a particular soft spot for children. She's capable of all manner of housework and entertainment, as well as protecting her charge with her signature attack Fleur Cannon, although this leaves her exhausted. She possesses the ability to read the emotions of people and Pokemon. The rabbit-like mechanical body is only a vessel piloted by the actual being, the multicolored gemstone in its chest known as the Soul-Heart. Long ago her body was damaged and rendered inactive, repeatedly traded as an antiquated oddity until it came into the possession of your extremely wealthy, extremely eccentric grandfather. When he recently passed he left you his Alolan beachfront mansion, and while exploring it you found her, mostly repaired over the years but still inactive. Like all Pokemon she understands speech but cannot herself speak. Steel/Fairy type. Only stands a meter tall.
