The Groom is a Zombie variant that appears during a Blood Moon or very rarely at any time in a Graveyard biome. He acts the same as normal Zombies, slowly walking towards the player to deal contact damage, while attempting to navigate around obstacles and opening doors if they are in the way. He has greater health than most other Zombies, and is dressed in a tuxedo and top hat. He can drop the Top Hat when killed, and also the Brain in the Old-gen console version and 3DS version of Terraria.
He does not have any variants, nor does he have an Armed variation in Expert Mode. The Bride is his marriage counterpart.
Following a Discord message where Redigit jokingly answered a Discord user's question of "who are the angler's parents" with "they ded", a Reddit user declared "officially starting" a theory of the Groom and the Bride being the Angler's parents, to which Redigit, likewise jokingly, replied "This is now canon."
The Bestiary entry for The Groom: "Tall, handsome, and dead. This unlucky fellow did not survive his wedding and is ready to take it out on everyone."
