So I think Klaus might be one of my favourite characters of all time (can we all agree that the ice cream van scene was hilarious?), but that's not why I'm currently obsessed with The Umbrella Academy soundtrack. It's dark, it's moody, it's super fierce - just the thing for writing angst filled scenes.
And may I recommend in particular the excellent first song 'Hazy Shade of Winter' by Gerard Way, feat. Ray Toro? It will have you bopping along as you imagine rain splattered fight scenes.
