Allister, also known as Onion, is a character from the widely popular anime series Pokémon. He serves as a Gym Leader in the Galar region and has captured the attention of many fans due to his calm and quiet personality, as well as his deep appreciation for all things spooky. His unique style and mysterious aura have made him a standout figure in the series.

Allister made his first appearance in the Pokémon Sword and Shield video games before eventually being introduced into the anime. As a Ghost-type specialist, he commands a team filled with eerie and fascinating Pokémon such as Gengar and Polteageist. His battles are not only challenging but also showcase his deep understanding of strategy and type advantages, earning him respect from other Gym Leaders in the region.

Despite his somewhat intimidating presence and fascination with the macabre, Allister is actually quite kind-hearted. He shows a great deal of care and compassion toward his Pokémon, treating them with respect and forming strong bonds. This gentle side of his personality has resonated with many viewers, making him a fan favorite.

In terms of personality typing, Allister seems to align with the INTP category. This type is often described as analytical, logical, and innovative—traits that are clearly visible in how he approaches battles and problem-solving. He tends to be reserved and thoughtful, often preferring solitude or quiet environments. However, he does show a more engaged side when it comes to Pokémon battles, suggesting that while he may be introverted, he still enjoys meaningful interaction in contexts he values.

Looking at his behavior and motivations, Allister also fits some characteristics of an Enneagram Type 5, known as “The Investigator.” He shows a strong interest in knowledge, especially regarding Ghost-type Pokémon, and often appears to be deeply immersed in study or research. He is private by nature, keeping his inner circle small and maintaining a certain emotional distance from others. This tendency may serve as a way for him to protect his independence and avoid situations where he might feel overwhelmed or vulnerable.

Moreover, Allister tends to approach challenges with his intellect rather than emotion, which is common among Type 5 individuals. He seems to fear being seen as unprepared or uninformed, which could explain why he often takes time to analyze situations before acting. While he may appear aloof at times, this is likely a reflection of his need for personal space and mental clarity rather than a lack of empathy.

All in all, Allister (Onion) is a beloved character in the Pokémon franchise. His calm demeanor, unique fashion sense, and caring attitude toward his Pokémon have helped him build a strong following among fans. Whether you’re drawn to his battle style, his personality traits, or just his cool and mysterious vibe, there’s no denying that Allister stands out as one of the more memorable Gym Leaders in the Galar region. While personality frameworks like MBTI and Enneagram types aren’t set in stone, they do offer interesting insights into who Allister is and why so many people appreciate his character.
