Briar has a lot of hobbies. First and foremost you could say that her biggest hobby is theater and musicals—both performing them as well as watching them, and she's actually a common guest at many of Wyndon's theaters.

Another unconventional hobby of hers is maths. Yeah, she looooves numbers, equitations, calculus, geometry, etc. She actually keeps many books full with equitations so she can solve them in her free time, she thinks it's relaxing. When she's at her rehearsals and can't carry heavy books with her, she brings sudokus instead. It is said that Briar can solve equations in her head and never got used to using calculators: if there's a problem that she can't solve mentally, instead of using a calculator she'd rather sit through thirty minutes of thinking LOL She also memorized many combinations to solve Rubik cubes, and she could solve them pretty fast in her youth, but is out of practice nowadays.

Another thing she likes are watching crime shows, cooking shows and dancing :3c

Kinda answered this before in previous asks, but to summarize, the following is a listed portion of Elio's hobbies outside of traveling and battling:

☠️Doing extreme training exercises - either ones that are trending or something he came up with on the fly to push himself. Typically, this includes spars and Aura cultivation.

☠️General outings with either his friends or his younger siblings whenever they're available. He enjoys their company and would gladly indulge in their immediate desires and obsessions... So long as it doesn't get out of hand.

☠️Tending to his Pokemon. A good cuddle with some of them, if they feel up to it (which is always). This includes doing maintenance on their respective Pokeballs and items.

☠️Before obtaining [REDACTED] after the subsequent [REDACTED] of [REDACTED], he enjoyed doing maintenance on motorbikes - being a motorhead even before his academy days. Typically, such enthusiasm is rationalized as Elio viewing motorbikes as symbols of "freedom" and "independence".

☠️Shopping at high-end boutiques and websites. This has become more habitual since it relates to certain investments he's made or sponsorships he's received from well-known brands and corporations, thus expected to meet certain quotas.

☠️Chilling to Lo-Fi Hip-Hop, which helps quell both his mind and body while expanding his imagination. It's one of the few things that keeps him on a proper sleep schedule, despite now needing fewer hours than the average person to be fully rested, and gives him a broader view of both the world and himself.

☠️Being a filthy Zekrom and B-Kyurem stan (Yes, I count this as a hobby! A vital one, in fact! 😤)

☠️Updating his social media pages with new photos, stories, and videos for his followers to enjoy. It's important to keep in touch with the fanbase while not getting too involved. Though, there are times when he would do hangout events.

☠️Reading research papers that are either sent to him by most of his elder siblings, or found on the internet; they mainly consist of either new breakthroughs or theories in medicine, Pokemon care, business, or economics - his primary focuses.

☠️Indulging in his epicurean side: trying new popular or foreign locales and replicating some of the dishes he's sampled in order to incorporate certain elements into his own cooking. Some of the videos and pics he's posted on his social media account are culinary-related and surprisingly gained overnight popularity. The locales he's visited, reviewed, and emulated have since gained a substantial increase in their business. Fans, casual, and to some odd degree - culinary professionals alike treat Elio as a culinary expert because of said posts, much to his displeasure since he never viewed himself as such a person in any way.
