As the title implies, this thread is for famous authors you'd like to see depicted in the currently running manga/anime series Bungou Stray Dogs, which features 18/19th century literary authors in the modern day as supernatural detectives or rogues. I have a few ideas myself (some of the less fleshed out ones I put up in anime/manga discussion).
Herman Melville: Obviously given his most famous work he'd have some heavy captain and sailor motifs. Most straightforward choice would be a burly older man in a captain's outfit, but given the show's tendency to use younger versions of historical figures I'd say a youthful looking boy with a captain's outfit and cap would fit better. He'd have a stereotypical seafarer's manner of speaking (in other words, he'd talk like a pirate), using expressions like "Avast, ye landlubbers!" and "Keelhaul matey!".
Mixing a little bit of Captain Ahab into his personality, he'd be a Port Mafia hitman with a tendency to get psychotically obsessed with any enemies who've escaped him in the past. Probably Atsushi or another one of the Armed Detectives would fight and give him a nasty scar in battle and then afterwards he'd be totally fixated on trying to hunt them down and get revenge (likely mixed in with a bit of Foe Yay as well, given what kind of show this is).
His ability, 'Moby Dick', would allow him to summon a gigantic monstrous white whale, accompanied by a great deluge of water so it can move around freely. It would be extremely powerful (able to level entire city districts easily) but Melville himself would be unable to directly control the whale, though it'd be influenced by his psychological state (i.e attacking those he's angry at). That, combined with its high destructive potential would lead the Port Mafia to forbid him from ever activating his ability unless under direct orders from a Mafia official (he'd probably ignore this once he's sufficiently obsessed with catching a target, however). Yes, this is a bit inspired by the reference to Moby Dick as a 'superweapon' from Fate/Extra.
So, what do you think guys? I've got a bunch of other ideas as well which I might post up here sometime later if this gets attention...
