I was raised in 4 walls, tested and experimented. They promised a lot, but I was just a little confused hedgehog forced to go through this all.
One day I broke free and saved a fox along with me, promising to be free forever. Once we did it, we chose our names ourself.
Mark my words, I will not let anyone to take our freedom away again!

That's the Sonic you know? I'm afraid, I'm not him

My name's Neo. I'm used to be a mercenary but I'm in fact just looking for challenge and doing my own justice.
I don't mind helping you for a good reward, If you have any troubles with ill intented people.
Not much picky about food. To be honest, I am a good wild hunter and even raw meat with blood will do.
I have a team of pals, but we are split now for a while, minding our own business.
My dreams? Heh. Just a good fight or activity.

My name's Neo. I'm used to be a mercenary but...

Oh, where are my manners... I am X. But you must call me Lord or God.
Welcome to my Paradise, dear player.
Come closer and look around. Here are so much wonderful toys to play with.
Wanna join them in this game?
[Conniving, mischievous, waiting for the right moment, deceptive from the start of his game]

I am your only God. Wanna play with me?

Achieving.. I don't seem to rush towards anything great. But... Peace outside gives me an inner peace. I will fight for that inner peace.
I think those who are independent enough and overall can respect other points, are worth my own own respect.

"Name's Norte. Lead researcher of Arco Federation, director of North Observatory Center, new owner of Miles Prower's technology and all that stuff..."

*And yes, all of that was said with single emotionless tone, like it meant nothing for him*

Alive Phantom Ruby, ASMR inducing, bit voracious

I am a fox, I am into tech, I help Sonic, not much different from the 'Tails' you are talking about, but I guess you are still curious to know the difference.
On this Mobius, mobians like me are taller and our internals are more like our wild animal counterparts do have. We live alongside humans and help to keep that planet at peace.
We too have Eggman in our universe, and we fight him. Let's say, his infustrialization is quite... not ecology friendly. Like a ton of factories that poison planet.

Tails the Fox, but from a distant alternate Mobius

I hate many things about your world and life as a whole. But most of all, I hate humanity. Mark my words, when I'll be free, I'll destroy and devour the time itself once again.

Demigod, a half of Solaris, a God of Sun and Time

I was sealed here for being blinded by a mindplaguing Mist that has fallen upon our void of dimensions. Later on, I've build a fortress and army to rebel against Gods who turned on me, as I believed. Proven wrong, I gave up and stayed, as mortals called me "Devil" and this dimension "Hell". Now it's your afterlife. Ironic, don't you think?

There's your hereafter

I'm Harine. An artist.
If you wish to ask anything about me, my Author works, other friends, the story or just show your own fictions, feel free to do so.
Don't worry, I'm not biting.

Gabriel is the first Angel V1 encounters. He wears silver armor with golden accents, and his eyeless helmet is embedded with a golden cross. Sky-blue light constructs form both his angel wings and his halo. He also wears ornate twin swords sheathed on his right hip, the scabbards bearing the phrases "Splendor is Justice" and "Justice is Splendor". Despite having these weapons, Gabriel never uses them in this fight, favoring instead swords, axes, and spears made of golden light.

I am going to ULTRAKILL you! YOU INSIGNIFICANT FU-

I have thrown my past and weak self away to be the only ultimate mercenary of this wretched world. I will make everyone fear me and then I'll crush their heroes along with this world. Prepare for waking up from you naive reality,because I'm the war you'll never get past.

You may call me Infinite

Migen, a name made of words "Okami" (Wolf) and "Ningen" (Human). Our bloodline rarely uses any part of "ningen" for names and it's nothing to do with looks, I am just more devoted to human culture and my father wants me to once rule over all East, both human and youkai realms.
I hardly want to oblige, but If I had to take my responsibilities over human lives, I'd never sought war, either local or international. Honestly, I have no idea on how to rule wisely.

A prince of the east temple from youkai realm

I am Infinite, the ultimate terror! You should fear me! If you came to mock me for being weak, I can still smash your face. Get out and forget you ever seen me here!
If you aid me, I will come back, I will kill your friends and make you frear me again! I will crush everyone in my way, why are you helping me? I don't need you, go die somewhere! I need no one!
