Here all the six cast of Them's Fighting Herds and their bios.
ARIZONA
Just as all inhabitants of Fœnum, Cattlekind were immensely concerned when the call for a Key Keeper went out.
If the whole world was threatened, that meant their beloved home, The Prairie, was as well! Immediately, one calf came forward to volunteer to be Cattlekind’s proclaimed Key Keeper and protect her homeland and the bovine way of life.

Arizona exemplifies what is best of Cattlekind. Honest, hardworking, honorable and brave, she cherishes the life she leads and believes that green grass, clear skies, and a life free of fences should be available to all of Fœnum. She’s immensely righteous, the kind of kid who fights off other kids’ bullies, who never tells a lie, who believes in always doing the right thing. In fact, she’s so idealistic she can seem a little naïve, and sometimes her good intentions get her into trouble simply because she isn’t always realistic about life. It’s kind of hard to believe such a big heart sits inside such a small frame. She’s only a calf, but her determination and compact, muscular build packs a surprising wallop! As an opponent, her greatest strength is… well, her strength. Though her horns are only budding, they’ll throw a challenger across the field, her back hooves hit like a freight train and she’s so literally down to earth, she’s nearly impossible to knock down.
Gameplay: Arizona tramples all over her foes with devastating headbutt attacks. She can quickly close distance and maintain her proximity with her amazing lasso skills! Keep close to your enemies with your above average movement speed and shorthops, then maintain momentum with your lasso grabs! Get in and stay in, as most of your basic attacks do not reach very far on their own!

VELVET

Once the call for the Key Keeper went out to The Tundra, absolutely ALL of the reindeer in the nation entered Rein’s competition to win the honor, for all the Deerfolk of Rein thought highly enough of themselves to take the prize. But it was a young doe named VELVET who ultimately prevailed. Delicate and lithe, she is by no means the strongest, but she is by far the fastest and most agile of the Ice Sprites’ pets, and she demonstrates a talent for conjuring and controlling snow and ice that no other deer could hold a candle to. Almost as if to flaunt her superiority to jealous competitors, Velvet’s fighting style is not only formidable, it is a vision to behold! Her technique could easily be mistaken for dancing, and she takes down her opponents with the utmost ease and grace. One would say she was simply PERFECT if being completely full of yourself was not considered a personality flaw— and she, for one, does not consider it so. Don’t get her wrong — it’s not completely “me, me, me” all the time with her. She does care about the fate of her world. She just knows it will take the best to save it, and that is undeniably HER.
Gameplay: Velvet's ice cold magic stops opponents in their tracks. She'll allow you to admire her beautiful sculptures, but only from a distance! Control your opponent's movement with your magical ice crystals from afar. Velvet channels her magic faster the farther she is from her opponent. Keep them out of your personal space!

For generations, the deer in Rein have been revered and pampered by magical, elf-like creatures called Ice Sprites. Besides using their magic to provide the deer with one of the most beautiful cities in the world, the food the sprites provide — golden oats — imbue the deer with their own magic, making them able to leap so high and far it seems they can fly, and giving them the ability to control aspects of the wintery weather of their homeland.

PAPRIKA

For decades it was believed that the reclusive Alpake Clan of The High Plains knew nothing about the world beyond the remote Huacaya Mountains. That is until they learned the Alpake had received news of the situation. Suddenly the whole lot of them just showed up in the capitol of High Plains, pushing —no, SHOVING— their champion forward with uncharacteristic fervor and enthusiasm before running away, singing with glee.

Her name is Paprika and she has a lot of love to give. A LOT. If only she could find somebody to give it to. Somebody. Anybody. She’s not picky. All you need to do is have a heartbeat and she will devote her heart, her life, her very SOUL to your mere existence. And should she have her heart set on you, whatever you do, don’t run. It seems that her neediness and desperation infuses her with some kind of super strength that makes her extremely dangerous! Her hugs are crushing, her declarations of adoration will burst your eardrums. She will leap passionately into your arms – and knock you through a brick wall. Once she decides you are the love of her life, there is no escape. You are doomed. Whenever Paprika the Alpaca is in the mix, love can KILL.
Gameplay: Paprika is quick on her feet and confusing in her approach. Her attacks are bewildering and full of fluff. Don't breathe that! This playful alpaca has tricky movement and specials to confuse opponents. Add even more variables to the fight with her randomized magic attack!

OLEANDER
When the call for a Key Keeper finally reached the unreachable ears of the Unicorns deep in the shady forests of The Woodland, it was ignored. The reclusive and reverent Order of the Horn does not participate in violence of any kind. They believe that Light Magic will ultimately prevail, though they did not presume to know how.

This was not good enough for one Unicorn — and this surprised no one. Oleander has been long known as the Order of the Horn’s resident rebel. Frustrated with the closed mindedness of her people’s philosophies, she longed for progress and new ideas, and she found these in a book. A book of DARK MAGIC. She believes, that harnessed for the right reasons, dark magic is just as good as light magic. But the use of the book and its spells has marked her. Unlike the rest of her clan, her white coat has turned dark and now they turn deaf ears whenever she tries to speak her mind. It’s no matter. She does not need their permission to save Fœnum. And when she does, she’ll prove that darkness is as good as light.

Gameplay: Oleander literally uses every trick in her demonic book to devastate her opponents. As she reads, her power grows and a horrifying creature makes its presence known! Initially Oleander only has enough magic to cast one type of projectile. Her gameplay transforms completely when she gains additional knowledge from reading her book, allowing teleportation, casting of spells mid air and explosive traps!

POM
Sheepkin, the citizens of the small city-state of The Meadow, are a democratic society, following the will of the masses, the herd, if you will. Problem is, all of the Sheep will vote for the very first suggestion any Sheep happens to make.

When they heard the call for a Key Keeper, they immediately held an election to decide if they should decide who to send. Amidst all the bleating, one small voice squeaked out an opinion. “Of course we should.” The Sheep were stunned silent. Someone who speaks their mind? Someone with their own opinion? How bold! How brave! She must be… THE BRAVEST OF THEM ALL! So a vote was called for and the decision was unanimous. The squeaky lamb, Pom, found herself charged with finding the key with only a small pack of Sheep Dog puppies to accompany her.
Instead of roaming Fœnum competing for the key, she is doing everything she can to avoid it, but she keeps running into the other Key Seekers. And to make things worse, her puppies’ protective instincts make them formidable fighters. She keeps winning the key! So the other Key Seekers keep tracking her down, picking fights! She’s desperate to find the strength to escape her predicament – but what she doesn’t know is that the one little lamb who had the strength to speak her mind just might have the strength to save the world.

Woof, Ruff, Tuft & Puff
You may be surprised by the notion of a predator not only existing in Fœnum, but actually living with prey. No one really knows how it came about that Sheepkin live side by side with Sheep Dogs, but the popular theory is that the dogs are descended from friendly omega-wolves who were harmless enough to hide with the sheep while the rest of their kind were disappearing. The wolves changed over generations, their predatory instincts evolving into protective ones. They now shield the Sheep from harm... and their own stupidity. That’s the theory any way, the Sheep cannot corroborate the story. Or understand it.
Gameplay: Pom is the unwilling leader of a pack of protective puppies. Watch your step, as her supporters are more numerous than you realize!
Puppet style gameplay allows you to control Pom and her puppies simultaneously to control a huge part of the battlefield! Bounce your opponent off of a carefully laid obstacle course of puppies for the KO!

TIANHUO

High above the clouds atop the highest of mountains lies the diminutive Empire of Huoshan (known to other Fœnecians as The Volcano), built over the gaping maw of an active, lava-spewing crater. The Empire’s subjects are Longmas, a very proud race who are half horse, half dragon. Every Longma is a member of the military, sworn not only to protect their beloved Empress (Daughter of Heaven, Empress of the Miniscule yet Mighty Realm of Magnanimous Magma, Lava, and Fire) and their honored volcanic home, but all of Fœnum itself.
It took the Empress not even a moment to make her choice for Key Keeper. Her name is Tianhuo, and amongst her people, she is undoubtedly the greatest the noble half-breeds have to offer. As Captain of the Imperial Guard, Tianhuo is the frontline defender of her Royal Highness!

For certain she is an intimidating sight, emitting stoic confidence, but not a hint of arrogance. She has no disdain for her opponents. In fact, she greatly admires skill and strength and cannot enjoy a duel unless she faces a combatant who offers her a challenge… and it takes quite a combatant to stand up to her bat-winged, aerial attacks or the force of fire she is able to magically conjure when she reaches her greatest speeds. Indeed, not many are even able to get past the daggers that shoot from her fiery, dragon eyes when she stares you down. No one is more disciplined, no one more determined, and even the Predators’ Champion should beware.
Gameplay: Tianhuo, Captain of the Imperial Guard strikes from above, below and all around! Flexible, aerodynamic, and explosive, she is a real firecracker! Flight-based attacks keep your opponent’s head in the clouds! Cancel any and all of your attacks into her Firecracker Magic attack to overwhelm your opponents, or use it to move quickly across the stage.

Time to write!

Velvet and Pom are my new favorites!

Hmm. The details in her bio make Tianhuo more different from RD than the others are from their pony counterparts.
