Really hard to answer this one, solely because... my greedy ass would want more than one 😂

So here's a comprehensive idea list of possible Elio figurines (they're all incredibly detailed):

👤[The Portable Argentium]: This is just a Nendoroid of Elio with a beaming and comforting expression, dressed in one of his casual outfits. He's either waving at you or reaching out to you for a hug.

👤[Gaia Essence]: Based on my commission from Nyan, it's a full-body figurine of Team Skull Admin!Elio simultaneously summoning Velek, his Zygarde, while channeling his power via the spring-green glow in his eyes; while intimidating, it has quite the cool factor to it. Typically, it would have special effects to further illustrate said power and summoning. (https://twitter.com/00_Homura/status/1322327700003037184?s=20&t=nWpD-37RkkghYyMcNzsBsA)

👤[Silver-Haired Spectral Sun]: Another full-body figurine, it would be Elio performing an intense battle pose mid-air as Molesurya - his Volcarona, and Estio - his Marshadow, are plunged into the heat of battle - launching their signature moves at the opposition. The earth beneath him would be torn asunder via fragments suspended in the air, and both Elio and his Pokemon's eyes would be intensely glowing to signify their synchronicity and power output. Elio would be wearing one of his later outfits in this one to better show off his buff physique. It's the counterpart to the [Exalted Frozen Venom] figurine, as it illustrates Elio's skills as a veteran battler.

👤[Exalted Frozen Venom]: The counterpart to the [Silver-Haired Spectral Sun] figurine, this one illustrates Elio's skills as a multi-regional Top Coordinator. Like before, Elio performs an intense battle pose - albeit grounded, as Heim - his Alolan-Ninetales, and Zhevariz - his Aevium-Milotic, are flawlessly performing one of their many elegant combinations during a contest showcase. As anyone would expect, Elio would be garbed in one of his many contest outfits - preferably a high-end well-tailored intricately-patterned designer suit, the floor beneath him is a contest stage, and Heim and Zhevariz's respective physical traits are properly highlighted.

👤[Monochrome Luminosity]: This figurine is just training gear-clad Elio emitting his silvery aura, causing the ground beneath him to shatter from the pressure. There are additional details such as his wildly flowing hair and clothes, his confident demeanor, and the sparkling accessory covering his Aura to better illustrate a glittering effect.

👤[The Wealthy Casual]: An on-the-nose titled figurine, it illustrates Elio in casual clothes confidently sitting on top of a pile of money - with additional stand attachments of Pokedollars flowing down all around him (i.e. Masato Sanada's introduction in Episode 1 of <High School Prodigies Have It Easy Even in Another World!>). Though harking to a Forbes cover recognizing his accumulated wealth and investment prowess at such a young age, Elio understands how others can see it as the silver-haired trainer/investor flaunting his wealth - which would be out-of-character for someone like him.

A bonus idea, since NSFW figurines are becoming more popular this year:

👤[Post-Workout Relief]: Not elaborating any further :^) (https://www.reddit.com/r/AnimeFiguresForAll/comments/vsqt1o/dtalon_studio_gojo_satoru_the_temptation_of_gym/)
