Astarion debuted in Baldur's Gate 3, released by Larian Studios in 2023, as a high elf vampire spawn and companion rogue voiced by Neil Newbon. The character quickly became a fan favorite online, inspiring countless edits, cosplays, and soundboard clips on TikTok and Discord. Affectionate nicknames like the boi spread through fandom posts celebrating his dramatic lines and expressive delivery. Short clips of his voice remain popular because they work outside the game as instant shorthand for flirtation, vanity, and roguish charm.
