The Devil of Zero
is a crossover fanfic written by Knightmare Gundam of Ni.
The story follows Vergil after his death in Devil May Cry. As he lays trapped in the void, he sees a light, and is summoned to be the familiar of Louise Françoise le Blanc de la Vallière. He was denied Heaven and served as a tool for Hell, where as she was derided and distraught. Both are prideful and both are powerful. Halkeginia is not ready for them...
The Devil of Zero provides examples of:
- Adaptational Nice Guy: Louise behaves considerably nicer, though this has less to do with actually being nicer and more to do with Vergil not being one she can lord herself over.
- Adaptational Species Change:
- In the DMC reboot and Darksiders games, nephilim were hybrids of demon and angel. Here, they're hybrids of human and angel.
- Sparda, at least in the past, was an angel in this story. In canon, there's no indication that there's ever a point were he wasn't a devil.
- Siesta is revealed to be partially a devil.
- Boring, but Practical: Louise questions why Vergil bought Derflinger in the first place since his Summoned Swords would probably be a better option. Vergil points out that 1.) those are typically used for ranged attacks and 2.) keeping one as a personal sword would be taxing.
- Brought Down to Normal: When an angel consummates with a human, they are punished by having all their power permanently sealed away, rendering them almost completely mortal.
- Celibate Hero:
- Angels are supposed to be this, but some end up consummating with humans at the cost of their power.
- Well, for a given definition of "hero" anyway, but Vergil never displays any romantic interest in anyone. About the closest he gets is Siesta, who reminds him of the woman he slept with in Fortuna.
- Composite Character: Vergil gets composited with Saito since he takes the role of Louise's familiar and takes the role of Derflinger's wielder.
- Curb-Stomp Battle: Vergil dishes these out like candy on Halloween.
- His fight with Guiche's Valkyries can hardly be called a fight given how effortlessly he cut them down.
- When he pulls out Abaddon, he makes short work of Zima.
- He doesn't even bother with Wardes and just kills him with a single attack.
- Dreaming of Times Gone By: Louise has frequent dreams of Vergil's past. She's witnessed his childhood, his battles with his brother (as both himself and Nelo Angelo), and his journey through Hell.
- The Friend Nobody Likes: The first Azazel was this according to Abaddon due to being really winy. Sparda apparently got so fed up with him that he chucked his spear-form into the mortal world.
- From Nobody to Nightmare: Abaddon finds it hard to believe that Mundus would become one of the most powerful devils ever known, considering he wasn't very impressive six thousand years ago and was kind of a wimp based on the older demon's words.
- An Ice Person: Zima is a draconian devil with power over ice and frost. This also applies to her Devil Arm form after Vergil defeats her.
- I Lied: Vergil admits to lying about Abaddon's destruction from the battle against Fouquet.Louise: Hey! You said it was destroyed when you used it against Fouquet!
Vergil: Obviously, I lied. - Klingon Promotion: After Vergil kills Zima, her lieutenant gives him command of her frost armies.
- Massive Multiplayer Crossover: Not on the Familiar of Zero side, but the lore of the Devil May Cry side is combined with elements of DmC: Devil May Cry, Bayonetta, and Darksiders.
- No Challenge Equals No Satisfaction: Something that Vergil has frustrations with is that there are hardly any powerful warriors in Halkeginia near his level. He actually starts to miss Dante because of how unsatisfied he is with the challenges there.
- Nominal Hero: Vergil is just as power hungry as he was in the past and as anti-ethical in his methods of dealing with his enemies. It's just that he's on the side of good due to being Louise's familiar.
- Playing with Fire: The Spear of Destruction - aka the Devil Arm form of Abaddon - can control and emit Hellfire.
- Smug Super: Vergil. The guy is powerful enough to annihilate anything Halkeginia or Hell throws at him, and he knows it. Much of his attempts to offer mercy are laced with condescension, as if to say "I can kill you at any time, but I'll give you this chance out of pity".
- Telepathy: Vergil's Devil Arms can communicate with him and each other telepathically. Vergil soon learns to sympathize with Dante's dealing of Agni and Rudra since they never shut up.
- Took a Level in Kindness: While he more or less acts the same, Vergil is slowly learning to care about more than just himself and his quest for power.
- Trapped in Another World: As Vergil is Louise's summoned familiar, he's basically stuck in Halkenginia. It's later shown that other devils are also stuck there for one reason or another.
- Worthy Opponent: While Vergil doesn't have much nice to say about his brother, he does acknowledge him as the greatest swordsman and warrior he's ever known.
