Voldemort, also known as Tom Satan Bombodil or Tom Andorson, is the main villain of My Immortal. He spends the entire story trying to execute his master plan: giving Ebony a gun and telling her to shoot Vampire Potter with it.
Role in the story
Voldemort first appears in Chapter 9, where he tries to force Ebony into shooting Vampire Potter with a gun. He threatens her, saying that if she refuses, he will kill Draco. During this confrontation, it's clear that Ebony outmatches him big time in terms of power, and it is at this point that he also debuts his signature look: an ugly, preppy man with no nose and no nose, who dresses all in black but is obviously not goffik. For some reason, he speaks faux-early modern English, threatening to Enoby, "If thou does not, then I shall kill thy beloved Draco!" Voldemort also does not seem to realize that killing Vampire himself would be much faster. In Chapter 12, it is revealed by Vampire Potter that Volfemort kidnapped Draco (or has him bondage, as Tara puts it). Enoby and Vampire break into Voldemprt's lair and kill Snaketail, his personal assistant. Then they save Draco and flee.
Volsemort later appears in Chapters 16 and 17, where he hijacks two MCR concerts that Ebony attends. Here he tries again (and again) to intimidate Eboby into killing Vampire. But during his second hijack, Albert Dumblydore turns into a gothic old man and chases Vlodemort away.
In his next appearance, Volzemort tries a more brutal approach: he flies into the Great Hall of Hogwarts, dressed as Darth Valer, and directly threatens Ebony in Dumblydore's presence. Sadly, he does not realize that Vampire is right in front of him, very easily killable, and just flies away.
Ebony later travels back in time to 1990 to prevent Voldemint from becoming evil, by trying to seduce him into loving her. The theory behind this is that if Volxemort knows how to love, he will not become evil. Here it is revealed that Voldemort's real name is Tom Bombodil. He also tells Ebony to call him Satan, which is his middle name. This makes his full name Tom Satan Bombodil. Tom also appears to be goffik and befriends Ebony very quickly. He tells her that he has a band called XblakXTearX, which consists of himself on gutter, James "Samaro" Potter and Serious "Hades" Blak on guitars, Lucan "Spartacus" Malfoy on drums, and Serverus Snap on boss. Ebony also succeeds in getting a date with him.
When Ebony reunites him with his ex Hedwig, Tom and Hedwig start to make out in the Great Hall. Here they are caught by Dumbledore and Mr. Norris. After being brought to Dumbledore's office, Ebony sees Morty McFli's blak tim machine and decides to jump into it. She takes Tom Satan Bombodil to the present, where he transforms into his later self Voldemort. Here he teams up with Snap and Loopin to finally take matters into his own hands and kill Vampire, and all the other goffs, himself. Ebony decides to do something and shoots Voldimort with an Abra Kedabra curse. Voldrimort's fate is left ambiguous, since this is where the entire fic ends.
Personality
Voldemort is established as very evil and preppy, but also wears black clothes, making him a poser. He is also very determined in following his plans to kill Vampire Potter, to the point he does not see common sense. Voldemort also speaks in (bad) Shakespearean English in the present - though he speaks normally in 1990.
His past self, Tom Satan Bombodil does not have the evil tendencies the present Voldemort has. Instead, he is a goff and has a band called XblakXtearX. He is also very easily smitten with Ebony and wants her to be his girlfriend.
Difference from the Original
The original Voldemort is a no-nonsense villain who goes to great lengths to get what he wants - even if this means killing his own henchmen. He likes to cause suffering to everyone who gets in his way and is so feared that even his name itself is a source of dread. Even as a child he is established to be rotten and beyond saving. Voldemort is also said to be one of the most powerful wizards ever.
The Voldemort of My Immortal is none of that. The only thing he does is basically intimidate Ebony and flee. While he does share the obsession of killing Harry Potter with his original counterpart, he does not have the intelligence to create effective plans, only sticking with an ineffective one; despite being very loosely based on one of the most powerful wizards ever, despite having LOADS of opportunities in the story to kill Vampire himself he instead keeps using the one same plan over and over again: FORCE ENOBY TO SHOOT HIM WITH A GUN. As a teen, he is established as a 'symphathetic goff' and happens to live in the 1990's instead of the more accurate 40's. Voldemort's great magical powers are largely absent in My Immortal, as he is easily defeated by both Ebony and Albert Dumblydore on two separate occasions.
Physically, the My Immortal Voldemort does not differ his canon counterpart, with Tara using the film incarnation as played by Ralph Fiennes as her primary inspiration. However it should be noted that the real Voldemort never actually wore heels as he did in My Immortal.
It is implied that Voldemort has telekinetic powers in "My Immortal". Even though he has these powers, he inexplicably never uses them. In fact, he BARELY has any of his magical powers, and many others are missing, as stated above. In canon, he can fly without the need for a broomstick. He is also shown to be able to see into the future, knowing that at some stage Hogsment and Hot Ishoo would be renamed as Hogsmede and Hot Topic respectively.
The gothic shopkeeper in Hogsmeade is named 'Tom Rid', and later called Tom Riddle - this was Voldemort's real name, which in full (Tom Marvolo Riddle) can be rearranged to "I am Lord Voldemort". However, in this story, Tom Rid has no apparent connection to Voldemort, past or present.
Tom Bombadil is a mysterious character appearing briefly in J. R. R. Tolkien's fantasy epic The Lord of the Rings. The same name is used as Voldemort's given name in My Immortal. The original Bombadil is nothing like Bombadil in '90s Hogwarts, but then again none of the Harry Potter characters are really themselves either.
Tom Anderson is the real name of Neo in The Matrix. It is also the name of the famous co-founder of Myspace. Based on these two last names it appears that Tara was just using any last name attached to Tom she could find, for whatever reason.
