"Zen" Cardio

"Zen", otherwise known as Cardio is the first generation casivian of Strength. Originally his name was Cardio, but over the years, he changed it to Zen (although some of his old children still call him by Cardio). Over time, his appearance has changed slightly, to depict more inner strength. By "strength", his element is inner, not physical strength. Zen is very determined and optimistic.

History
Zen doesn't really give second thoughts anymore, he just relies on his initial first reaction, and if there's consequences, he accepts them. He isn't as philosophical anymore, but believes that instinct is the true essence of real strength.

Zen was once a calm and prideful casivian, living in Bala, possessing a strong set of morals. Only issue is that he tended to only see things in black-and-white, and didn't really understand the idea of opinions. However, he remained tolerant and accepting. Due to recent events, his physical form underwent drastic change, making his fur whiter, his markings alter, and his tail changing into an actual heart. During this time, his calm and rational thinking seemed to disappear, and went out to gain more strength. Zen began to give more and more into instinct, believing in first instinct was best, and just accepting whatever consequences may come of his actions. Zen left the city, and began to live in the wild.

Children
Over the years, Zen has had several children, and is expecting to give more in the future.

Trivia

 * Zen is one of the original first generation casivians.
 * His tail is still a long furry Verent-like tail, which used to have a chain leading to two, heart-shaped metal pieces. But now, it ends in five, curved rib-like bones making a spherical cage-like structure... inside is an actual, beating heart. This is not Cardio's heart, nor does it really belong to any other being... it never seems to stop, speed up, or slow down. The bones represent strength, protecting the heart and shielding it from harm. It is believed the heart inside actually transformed from one of the fake metal hearts, but nobody saw when the transformation happened and can't be sure.
 * Zen is unable to fly with his new wings, however, he is able to glide.
 * Zen is named after the strongest boss from the game Cubivore.
 * "Strength" means mental strength, not physical. Several strength casivians have hearts in their design due to this.
 * Many of his children see him as a strong father figure.
