Undertaker's an eccentric, enigmatic individual who giggles frequently, appreciates laughter, enjoys frightening others and provoking reactions with his strange mannerisms, and spends a considerable amount of time in coffins. Because corpses, many of which victims of the underworld, are ordinarily delivered to his place of business, Undertaker's able to inspect them, (whom he refers to as his "guests") remove their organs for research, and obtain useful information — which he refuses to exchange for "the Queen's money" as he dislikes Queen Victoria. Rather, he expects those seeking information on the corpses to amuse him in some way. Undertaker's profoundly attached to the Phantomhive house to the degree that he seceded from the Grim Reaper Dispatch to focus his efforts entirely on manipulating life and death in hopes of restoring the late Phantomhives to life. Despite years of experimentation where he resurrects the dead via connecting fake records to their Cinematic Records so that such will never end, he lacks the ability to construct a soul; the corpses he revives are Bizarre Dolls, which are, more or less, "flesh dolls without a self." Nevertheless, he, with steadfast resolve, continues to experiment and sees beauty in his Bizarre Dolls where others see depravity. He considers "Ciel Phantomhive" his masterpiece. Undertaker regards a particular chain of six mourning lockets as his "treasure." (Engraved on one of the lockets is 13 July 1866, Cloudia P.) He eventually entrusts his treasure to Ciel. During the Luxury Liner Arc, Undertaker was dressed as Charlie Chaplin. Ironically, Charlie Chaplin was born on 16 April 1889, the day before the Campania set sail; April 17, 1889. Undertaker's design was based on the design of the protagonist of a pirate manga Yana Toboso planned before she started working on Kuroshitsuji.- Undertaker puts up the most random shit during the holidays; it’s as annoying as it is amusing to try to decipher what he’s trying to say, or if he even is trying to say anything.
- Undertaker’s friends are the squirrels and the squirrels are his friends.
- Hahahaha, Undertaker’s dead inside; he still hasn’t found the pieces of his heart the last time someone broke it. Because I’m totally sure that even though he tries not to let people in, someone just does and it feels like a hurricane to him.
- Don’t let him get bored; a bored Undertaker is a bad thing!
Undertaker's a retired Grim Reaper, and as Grelle and Ronald claim, a "deserter." He'd served as a Grim Reaper for a long time, repeatedly reaping souls in a relatively peaceful, indifferent fashion. This earned him the status of the best Grim Reaper in the Retrieval Division. During his time at the Dispatch, Undertaker was only known by his registration number: 136649. Eventually, he grew tired of the mundane process: Seventy years ago, Undertaker tried to leave the Dispatch and in his attempt, destroyed half of its headquarters. Around twenty years later, he tried it again and succeeded. Sometime later, Undertaker established his funeral parlor, began to experiment and tamper with human life, and became acquainted with Vincent Phantomhive. His intermittent business relations with said Earl earned him the status as one of the "Aristocrats of Evil."- What if Undertaker reaped Vincent's soul that night? Maybe that's what he means when he says that the earl is still with them. The body may have truly burnt to ashes, after all. It's not like Undertaker cares about rules anyways, and since he obviously has strong feelings for him, he could've easily tried to savor the soul in order to revive him later on as some have already mentioned the bizarre dolls. Plus, he still has that death scythe. Maybe he knew what was about to happen, or at least found out in time to be the first Shinigami there. Maybe other Shinigami actually arrived and tried to take the soul from him but he fended them off; perhaps that's how he got into an actual conflict with his kind and they scarred him as it had to happen in a fight with somebody wielding a death scythe. I doubt anything else could inflict permanent wounds on a Shinigami like that. I also don't think the Undertaker is Cedric; I feel like that would just be too easy to put together and some of you had already pointed out why that would not be possible even. I definitely do feel like he's part of the family, though, despite not really being a fan of the idea myself.
