hey that's completely legit. From that perspective I would say any of the vergil fights, particularly the third one for how difficult he is. Some bosses are tediously difficult (like waiting for geryon to slow the **** down so you can deal some damage) but vergil3 is a toe-to-toe brutal slugfest and it's awesome. Vergil2 ends up being my favorite because the soundtrack for that fight is amazeballs awesome. Combining two different character themes and remixing it into a fight song? Yes please
