Generally speaking, he's not all that gimmicky compared to other bosses later encountered.

Warmup Boss: He first appears in the second fight of the game, during the tutorial.

One is single-target, the other hits your whole party, and both inflict bleed.

A Taste of the Lash: Two of his attacks, Punishment and Rain of Whips.

Outside-Genre Foe: A heavily armed highway robber isn't high on the list of bosses one expects in a game about eldritch horrors and other supernatural beings.

No Range Like Point-Blank Range: Like the Highwayman, he carries a flintlock and sometimes uses it at point blank range.

Large and in Charge: He is noticeably taller and larger than any other humans, to the point that he occupies two positions in the formation system.

In the Hood: Wears a green hood, like his fellow bandits.

Giant Mook: A huge brute of a man, he fills two spaces and looms over all the other Brigands and the party alike.

Dented Iron: His bare chest is covered in scars.

Degraded Boss: Guys like the Blooodletter occasionally appear as a regular enemy after the tutorial.

Badass Normal: Like all the Brigands, the Bloodletter has no supernatural powers, just size, gunpowder, and a mean streak.

A huge bandit serving as a boss during the tutorial, he recurs later in the game as one of the more powerful members of the Brigand faction.
