One time in a steampunk gunslinger campaign I played a half-elf sniper/artificer who was secretly a prince running away from his tyrannical king/queen parents to join the grassroots resistance against great evils conspiring with the crown. It was one of the most complex/fun characters I have ever played, and getting the party to avoid interactions with royal guards (so I wasn't recognized) without outing myself was a fun silent puzzle between myself and the DM. It was also funny that I was basically The Handsomest Fellow (tm) who wanted to be judged on merit instead of beauty and had to deal with a ton of unwanted attention from NPC's, and tried to make myself look as haggard and disheveled as possible at all times, lots of fun all around.
We played this campaign for almost 2 years, and the LAST session before we all graduated and moved away and went our separate ways ended with me getting recognized and outed to the party and I am still salty about that cliffhanger like 8 years later lol
Also our Paladin was basically Rob Halford (Judas Priest), his holy mount was a motorcycle, and I convinced the DM to let me craft and attach a permanent charm of flight to said motorcycle...
