The one from 5E that most people balk at, but really should not is a religious archer/assassin. A tiefling descended from Glasya (Daughter of Asmodeus and a Lord/Lady of the 9 Hells), Myska Urge began her career as a ranger hunting in the underdark, but she preached about how her ancestor, Asmodeus, was a necessary evil and should be praised for his efforts in fighting the Blood War. She delved out Asmodeus' 'justice' from a great distance and became one of his most feared enforcers in the Mortal World.
Her build? 5 classes.
Glasya Tielfling Courtier: Gloomstalker Ranger 5, Cleric of Order 1, Divine Soul Sorcerer 5, Battlemaster Fighter 4, Assassin Rogue 3, Divine Soul Sorcerer 3 more (to 20).
She began as an archer, then spent levels 6 to 11 focusing on her faith towards Lord Asmodeus, and then levels 12 to 20 (while still faithful to Asmodeus) focused on making her better as an Alpha Strike Assassin. She retired from adventuring and founded a school that trained mortals to serve Asmodeus' goals in the Prime, and then travel and fight in the Blood War.
I enjoyed her so much that I am 'rerunning' her in a second campaign. This is the only 5E PC that reached high levels that I have decided to 'rerun' - although the 2nd game may have, unfortunately, stalled out.
