Jirachi

He has a white dress (but not a woman's, rather a monastic one). Yellow hair, Similar to a star, Black eyes with blue stripes under them (no, it's not makeup). He also has small yellow wings.

Personality
Because Jirachi is initially considered to be the second most powerful Mythical Pokemon, as it's established that he's second in line to Arceus[1], he abuses his rank and wishing abilities to wreak havoc and cause mayhem. He's pretty carefree, and acts rebellious, as according to him, the Legendaries don't follow the rules, so "why should he?"[2] This implies that he was once an obedient and decent legendary who initially followed the rules, but after witnessing the Legendaries constantly breaking the rules, had his behavior negatively influenced and began his rule-breaking nature. Jirachi acts overly confident in his abilities due to being able to wish his way into getting out of problems. Whenever the mythical mon is angry, he "evens out" his anger by seeking vengeance; however, his methods of enacting out vengeance includes manipulation, such as the time when he created a false story on how he resurrected Tepig to pin the blame on both Cyndaquil and Bulbasaur, while at the same time trying to convince the jury to be on his side.

in summary: Jirachi is an immensely powerful being with a capricious, childish, and deeply irresponsible mindset. Although it has the ability to grant wishes and alter reality, it does not act with deliberate evil intent, but rather with a complete lack of understanding or interest in the consequences of its actions. For Jirachi, the world functions as a source of entertainment: it grants miracles for fun, breaks cosmic rules because they seem absurd, and treats serious situations, such as death or the collapse of the natural order, with levity or sarcasm. It has a strong need for attention and validation, reacting with mockery, emotional manipulation, or tantrums when questioned. Jirachi perceives himself as someone who “just wants to make others happy,” but his inability to understand boundaries, grief, or responsibility makes his actions dangerous, chaotic, and often cruel without him realizing it.

Design
He mostly looks like his Pokémon counterpart, while other pokemon like Arceus that were stylized for the series, jirachi doesn't have this treatment as he has their black eyes with white pupils, something more accurate to the gamefreak design, Jirachi concept pretty much represent the shooting star for a wish concept that is represented by their star shaped head, also the tags that this pokemom has resembles the tanabata festival
