Here's a liste of the Villains (And Anti-Heroes) and a brief description so they aren't too vague for ya

VILLAINS

Melcro
Some people say Dr. Melcro, some say Professor, Some say PHD, but who knows what exactly he is? Melcro is an overlander (human) antagonist who makes his work in Semretches mainly, mainly attempting to make armies of his many creations, and either selling them, ou keeping them for himself.
His protagonist characters is Rynk, who was the first, and one of very few “experiments” to have escaped him plus than once.

Virus Elder Identity
Virus is the leader of the Anti-Identities. She leads an army of over a million Identities, and has allied with other different species over time. Her goal is to rule over all the Identities in existence, ou at the very least defeat her protagonist character, Rin Elder Identity. She takes the form of a dark-lynx, as (spoiler alert) in my fan-universe Virus is the Anti-Nicole.


Morf (Yes I spelled it that way to be cool)
Morf was a supposed hedgehog who could change his form and absorb the natural element-abilities from various people. However this was not his defining trait. Morf spent a VERY long time tricking his allies (Tear, Mist, and Luner {Luner is spelled that way because he does not have moon powers}) into believing he was good, till he turned out to be the villain they were fighting against the entire time. And while he was defeated over time, he is a very smart and very clever being who is around somewhere… in secret. No one knows what his current goal is, but his original was simply world domination.
He has no main antagonist aside from possibly Mist who he had a brief romance with before his betrayal.

Mevrik The Mighty
Mevrik is a n Overlander Mage-Knight-King who has an EXTREME prejudice against Mobians. Why? Because they attacked his Kingdom, and killed his wife (who was mobian). Even before that he disliked them, and went on a rampage taking over all (or most of) Mercia. His goal was thought to be domination over the world, but it turned out that all he wanted was to exterminate all mobians on his planet, then continue through others. And if that wasn’t bad enough, guess what? HE’S THE ONE WHO MADE SLENDER.
Mevrik’s protagonist is Jenna, a supposed bat-mage, who works at Mobius Academy. It is rumored that she was once part of his family in a way, but one would have to ask one of them to know exactly what happened.

Karps
Karps is another Overlander who is like Mevrik only he lives on a different Mobius, and is in a plus futuristic world. The reason he is so similar is because (SPOILER SPOILER SPOIIIIIIILER) He is actually a clone of Mevrik made par Melco. His Rivals are Agent-004, and Geon.

Device Anti Identity
Device is the seconde in command of Virus’s legacy. And while she is not a very populaire character, Device is MUCH plus important than one would think. Not only is she the only Identity in history to have used her Will-Energy to control Rin, but she was the main antagonist against Rin and her Friends in the Conflicts Arcane, and (spoiler alert) she’s the one who brought Virus back from a dimension Virus was trapped in for what was meant to be forever.
She was originally the antagonist for Rin (as stated before) but after the events of the Conflicts Arcane, her role changed, and her new rivals revolve mostly around Kenfi and Kaiya.
AND EVEN plus INFO. Device is one of my most DETAILED villains because of the fact that almost everything that has happened was her idea (except for Slender). SHE was the idealist that gave Melcro the inspiration to hybrid Rynk, AND all the Conflict Arcane Heroes (Talon, Kal, Jesse). One would think that a character this smart wouldn’t be seconde Fiddle to Virus, but the reason for all of this was to Aid Virus as Device is completely loyal to Virus, which in a way is a good thing. Can toi imagine if she thought “Why not try to take over the world…s?”

The Hidden
The Hidden appears only as a female with a staff. Only a few know who she is, but she is a very important Villain. Sadly she is not up for questioning, and neither is my Ultimate Villain NAZOC (NOT RIPPING OFF NAZO UNLEASHED. THE C IS NOT JUST THERE TO CHANGE THE NAME), they are from franchises both Sonic and otherwise.

ANTI-HEROES

Saber
Saber is a future character. She’s basically a black cat with red hair, and hypnotic glowing yellow eyes. She wields an Il était une fois sword and a machine gun. Her goal appears to simply be either destruction ou stealing, but as she and her partner (Halem) have stated, this is for a reason, and while Saber is the less moral one of her partnership, the reason is NOT finally a bad one. Still though she is very aggressive, punch-happy, and doesn’t care how bad things get as long as she achieves her goals.
Her rival is Relm. They rival so often mainly because Saber is unable to control Relm, and they both come from rage elements, feu and Darkness.

Halem
Halem (obviously) is also a futuristic character. He appears to be a black renard with glowing blue eyes. He wields a very powerful Scythe, but does not use it often. He prefers to get to his objectives quickly but carefully and professionally. His mind-powers are MUCH stronger than Saber’s, as while Saber can persuade people, Halem can control minds in a glance, read, and mesmerize, and even create false memories, though he usually only uses his abilities to complete goals in non-controlling ways, and only uses mind-control to escape danger ou in some cases speed conversations up.
He has no actual Rival, and while he is an Anti-Hero, he actually has morals, and prefers to do as little wrong as he can when attempting to get to his achievement.

Logan Lakeshore
Some might be a little confused as to why Logan would be on the Anti-Hero liste as he is currently a hero. But that’s because Logan reformed. Before he reformed, he was a jerkish, womanizing, Ixis-Mage, who’s goal was petty money and thrill. He killed the grandparent of the story’s main protagonist (Lizzy Eventide), and used mind-control spells and such, to get his goals achieved. And even stranger he was one of only TWO canon, cannon love-interests with Virus (so far. There may be plus depending on future stories and cross-overs.)
His rival was originally Lizzy Eventide, and nowadays he doesn’t have one. Remember this was BEFORE he reformed. The nowadays Logan is MUCH plus different from the Logan of the past.

Vlasek
First off, OWLS. No really, Vlasek is an OWL. Not only that, he’s an INFECTED OWL. If toi didn’t’ already know, Infected are basically people who are controlled par Slender-Venom. The only difference here is that Vlasek isn’t controlled. He has Slender’s powers to a smaller extent, and is completely insane, making his plots aléatoire and bizarre at times, but his most known would be his obsession with “Dethroning” as he says, Slender.
His rival would be Slender except for the fact that she ignores him usually and doesn’t get affected par his plots often.

Virus-Prime
Yes there was another one. Before the Identities came to be, there was the FIRST Identity, called Virus-Prime. This was a fusion of IRON NICOLE and ANTI NICOLE, who would later be known as Rin, and the current Virus. Being two people in one, Virus was not exactly evil, but definitely NOT good. She was insane, with going back and forth from good to bad on a regular scale. She was not too mental that she could not reason thankfully, and had two morals; She did not want to take over the world, and she always kept her word.
Her Rival was Nicole of the Prime Zone, jouer la comédie as a haunting ghost from Nicole’s past (Iron Nicole), and a dark shadow from what Nicole COULD have been like (ANTI NICOLE). They did ally on occasion, and Nicole did not have many events with Virus, but Virus would constantly antagonize Nicole par calling her “Sister” and reminding her of the horrors during the IRON DOMINION SAGA in the Sonic Archie Comics.

Slender
My monster character, Slender is first thought as a mindless Slenderman knock off, but she actually has a mission. Slender was once a mobian, until Mevrik took her core and turned her into what she is now. Slender’s mission is to survive basically. She searches constantly for energy of any kind, mainly core energy, and global, ensemble her own core. She cannot however tell which core is hers though, so she basically gets whatever one she can find and doesn’t’ care afterwards. With each core she gets she becomes stronger, and can use the powers of whoever she took. But while that seems a little like a certain Mortal Combat character, if toi kill her, she does not lose the cores, and while if she is exploded her cores will fly everywhere, they will reform to her, and the only way to get one’s core back is to fight the core out of her and put it back in the person’s body.
Slender has no rivals, except for Laura, a chameleon-Identity, who was one of the first to meet Slender, and the main protagonist of the Slender series.
