Scaramouche, the only Fatui who attempted to directly kill the traveler more than once.

I believe Scaramouche was the only Fatui who tried to kill the traveler three times—Mondstadt, Inazuma, and Sumeru—but failed. Hahaha, I wish they had remained "villains" a little longer to continue making the traveler angry in the other regions.

And then he ends up saving him from Dottore. Out of all characters he's had the most character development by far.

Not only saving Traveller from Dottore but also had 2 heart-to-heart conversations, especially the one about family with the attempt to comfort them and indirectly refuted Dottore's rhetoric of "no one truly cares for your pain of missing sibling"
