Enemy by Imagine Dragons for Tigerclaw/star. I first heard this song on the League of Legends Netflix show
Arcane last year and have been obsessed with it ever since. There is even an animation meme that just came out on Friday which fits perfectly in regards to the choice for my favorite
Warriors villain's theme song.
Previously, my preferred theme song had been another one associated with one of the LoL game trailers for Tigerclaw/star and thus Kingdom by Jaxon Gamble would fit him as well.
Other than those, I also still got these from another "character theme song" thread on here:
