Aquina is a light blue cat who lives in Green Hill with her Chao Stephanie, her friend Mighty, and his Chao. She has a usually calm personality, but can become very angry and destructive if pushed too far. She has the ability to manipulate water, ice,and steam, though she mostly uses the former two. She is usually focused and mature (for her age), but there are a few things that can distract her.


Early life

Not much is known about her life until after her mom disappeared. She took care of her sister, Loner, until she one day got lost and met Stephanie. Soon after, she met Mighty, and they became friends quickly. The origins of her powers are unknown, but it is assumed she has had them since birth.


Aquina is a generous and caring hero, who always does the right thing. She likes to help people, though she always appreciates some quiet time as well. She is usually calm, but hurting her friends or infuriating her will drive her into a frenzy.

Powers and Abilities

Water and Ice

Aquina is able to control ice and water, using them in both combat and everyday life. These powers do come at the cost of being weak to heat, however.

Underwater Skills

Aquina can breath underwater, able to stay under forever. She can also hear sounds underwater, and her clothes adapt upon entering the water to allow her to swim more efficiently.

Natural Abilities

As a cat, she is very agile. She always lands on her feet, is able to use her claws in combat, and can climb fairly well. However, for unknown reasons, she is unable to see in the dark like most cats.


There are a few things that can change Aquina into other forms. Here is a list of the main transformations she undergoes.

Super Aquina

When she uses the seven Chaos Emeralds, she glows blue, able to fly, becoming invincible, and having her powers increased a hundred times.

Hyper Aquina

When using the power of the Chaos Emeralds and the Super Emeralds together, she becomes Hyper Aquina, a hundred times faster and stronger than Super Aquina.

Angered Aquina

When angered enough, Aquina flies into a frenzy, becoming more powerful and destructive. Pouring a bucket of water on her head is usually enough to end the rampage.

Darktail Aquina

When Erazor slew Mighty with the flaming arrow, she activated the rings with her emotions, turning into her most powerful form and attacking, along with wishing Mighty back to life.


Aquina's main weakness is heat and fire, because as a controller of water and ice, those things are dangerous, even deadly at high amounts. She doesn't have many other main weaknesses, but she becomes nearly hypnotized by catnip, as most cats do.


Aquina has met many friends throughout her adventures, and a few enemies too.

Mighty the Flying Squirrel

The two met after being separated from their parents. Though they were only 10 years old at the time, they quickly became good friends, and almost as quickly, heroes. Though his element is opposite of hers, him controlling fire while she tames ice, they remained great friends for years. Soon, they grew even closer, and after a bit of tension, admitted feelings for each other beyond friendship. They are rarely seen apart, and care for each other to the point of sacrificing their life to save the other.

Stephanie the Chao

Stephanie is Aquina's companion, and they share a sentimental link. They met each other on the same day they both met Mighty and Stephanie's brother, Steve. They share a peaceful bond, though Stephanie can be mischievous, such as when she and her brother covered their ceiling in mistletoe to tease Mighty and Aquina.

Scrambles the Chao

Scrambles was kept dormant in his egg for fifty years, cared for by the Robotniks. He was to remain in his egg for another hundred years, but Eggman, in a fit of rage, freed him from the egg accidentally. His speech quickly developed, and his technological mastery came soon after. He took over Eggman's base, making several attempts to eliminate the heroes, though Eggman saved them every time. Eventually he kidnapped everyone, but upon meeting him face-to-face, everyone began to marvel at his cuteness, petting him. As he tried to retreat, he fell on the ground, losing all of his memory. Mighty and Aquina raised him, and though he has developed some, he will remain as a baby for a long time. He takes more after Aquina, his breath being mint cold, but he loves technology, to the point where he's learned to hack the world around him, manipulating the minds of anyone he pleases. Isn't that adorable?

Loner the Tabby Cat

Loner is Aquina's younger sister. She was affected more by the disappearance of their mother, eventually turning to the side of evil and becoming hateful to her sister. For a short time, she played nice with the others, but was plotting to take over the world. She was stopped, however, though she continued her malovent attacks until she nearly killed Mighty, when her mind was hacked by Scrambles and turned good. She barely managed to save him, but Aquina did not forgive her until she gave her a small robot kitten as an apology.

Harriett the Tabby Cat

Harriett is Aquina's mother, who disappeared when she was young. They missed each other a lot, not seeing each other until Harriett was busted out of Eggman's first base by Mighty and Aquina. They are very close and share a special bond.

Macy and Ace

When out on a walk, Aquina discovered two twin kittens, lost in the cold. She and Mighty took them home, giving them names and raising them. When they need to go out and adventure, they leave the kittens with their mothers so they aren't harmed.

Nack the Weasel

Nack hates Mighty with all of his being, and has sworn to destroy him. Obviously, Aquina doesn't quite approve of this, and so he is her and Mighty's arch-rival.

Sonic the Hedgehog

They met during both of their first adventures, and have been pretty good friends ever since, though they often equal or outshine Sonic in many things.

Dr. Eggman

Shortly after meeting Mighty, they found Möbius threatened by a moustached villain. They realized how strong they were, and sought to foil his every plan from then on. They hold an everlasting rivalry against him, though there are a few villains diabolical enough to convince him to help them, one way or another.

Miles "Tails" Prower

Tails often assists Aquina and Mighty when they need technology or medical help. He also occasionally watches Scrambles and tutors him.

Amy Rose

The two met when Amy was captured by Eggman, and though they don't hate each other, Aquina does somewhat see Amy as a nuisance like everyone else..

Metal Sonic

Aquina cannot stand the sight of Metal Sonic, tearing him up whenever possible. This goes far back to when they first met and Mighty was injured by him.

Knuckles the Echidna

When they first met, Knuckles was misinformed of her and the others' intentions. He impeded their progress towards stopping Eggman constantly until Eggman betrayed him. He is mostly an ally at the moment, allowing them to use the Master Emerald when needed but otherwise guarding it with his life..

Shadow the Hedgehog

They first met Shadow when he got Sonic framed for robbery. They escaped the city and attempted to fight him, learning of the Chaos Emerald's true power. They held a rivalry against him until Biolizard was discovered and he had his epiphany. They later met him on a hillside, surprised to see him alive as he pondered his identity. They began to help him find it, until he was led astray by Black Doom when they tried to stop him from becoming evil. They fought Devil Doom with Shadow, and their bond as friends was sealed. They visit him occasionally for problems related to the Chaos Emeralds.

Blaze the Cat

Obviously, they are opposite cats, Blaze being a pyrokinetic and Aquina being hydrokinetic. They get along well, and Blaze travels back through time to see them on important occasions. There was a period of time where she and Silver lived with Aquina and Mighty, though events that followed eventually drove them back to the future.

Silver the Hedgehog

When they met, Silver believed that Mighty was to cause the bringing of an apocalypse to their world, which neither Aquina nor the apparent 'Iblis Trigger' believed. After going at each other and trying to save the princess of Soleanna at the same time, Silver eventually saw the good in the heroes, helping them through their journey. He is always with Blaze now, having lived with Aquina and mighty for a while.
