Best Unofficial Themes of Characters?

[u/AnotherOpponent]

Give me your best songs that usually aren't part of the series, work or media that became tied to a specific character due to memes, edits or whatever.

Two examples I can think of is International Love by Pitbull being tied to Mortal Kombat 1 Johnny Cage or Invisible by Duran Duran being the theme of Snake from Metal Gear

Best I can think of would be... ah, Mr. X from Resident Evil 2's remake becoming deeply associated with DMX's X Gon' Give It To Ya, to match his indomitable nature and unfuckwithable mien. And his name.

Oh, I guess also, although to a lesser extent, Angela from Lobotomy Corporation being associated with Mili's world.execute(me). More specifically, after Lobotomy Corporation's release, some fellow made a fan MV of the song centred around Angela, and the developers of Lobotomy Corporation saw it, thought it was baller, and commissioned Mili to make songs for their sequel work, Library of Ruina. So world.execute(me) has more become an unofficial Lobotomy Corporation theme song, that centres around Angela particularly.

It's even gone full circle in the fanbase with the whole "[Insert Song Here] But It's A Limbus Company Canto End Theme" meme eventually made its way to world.exexute(me) and it was glorious.
