Kieran Valentine is a 2012-introduced and cartoon-only character. He is a son emo (emotional) vampires with immense powers and a narcisstic, cruel personality that make him dangerous to be around. He plays a sick game of seducing girls, sometimes by hypnotism, and then intentionally breaking their hearts to add to his "collection", which makes him gradually grow stronger. The only one who ever escaped his influence, if only by coincidence, is Draculaura. A second attempt to obtain her heart even resulted in him losing his entire collection and with that all his powers. Valentine likes to act like a smooth and in-control gentleman, but when in trouble, all he'll do is cry for his mother.
He is voiced in English by Jonathan Lipow.
Living in Transylvania in early years, Valentine learned how to settle his emotional vampire powers, by doing what he though he was best to fill his need of love, steal it from his pretendents. Continuously breaking the hearts of any girl he would charm, his powers would be stronger and stronger. However this method never made him entirely confortable, but due to lack of knowledge of other methods, he kept on doing the same, thinking that he if got used to it, it would eventually seem right.
Eventually he came across Dracula's daughter, Draculaura, with the biggest heart he had ever known, perfect to complete the love he needed to adquire more of his love powers. Almost filling her entire heart, prepared to break it, Draculaura had to flle, after a missunderstanding with the local humans. He continued to do his same old practices, only this time with anger and hatred of himself for not being capable to have Draculaura's love stolen.
Centuries later he receives a call from who he thought was Draculaura, only in fact it was her nemesis Toralei, asking him to come to make a visit to her at Monster High. He eventually joins Toralei in her plan to make Draculaura and her boyfriend Clawd break up, which would benefit him to rise is ego again, with another chance to collect Draculaura's love. However the task is as hard as previously, making him resort to hypnosis, which like before fails due to the strenght of Draculaura's and Clawd love. Valentine is devasted when he is pushed into the Pit of Eternal Body Odor at the catacombs of Monster High, which weakens his emotional vampire powers, due to the lack of love he receives as a consequence to his pungent smell.
Lonely and devasted, Valentine lived in solitude in his mother's garage, embarrassed and excluded by everyone, even his own mother who refused to take with the stench, until one day a goblin lady came to his home, claiming to be a friend of his mother, and requested help in her unwanted animal shelter, as a cleaner. During a year, he cleaned and took care of the animals, giving love to them and eventually he realized that love isn't something that can be forced, but instead it is something that requires work, like the love he received from the animals after treating them. With this his stench dissapeared.
Valentine is mischievous and scheming, using his quick thinking and allusive facade to his advantage. Like most vampires, he is very arrogant and aristocratic, he sports a fake southern accent and a masked personality to get what he wants. He often convinces girls he's created Valentine's Day just for them in order to win their hearts.
Recently, Valentine reappeared in the comic book I Only Have Eye For You, where he appeared to have turned over a new leaf and, and attempted to help other monsters find romantic dates for the Fraidy Hawkins dance, and tried to make it up to Draculaura and Clawd by paying for their date. His efforts didn't quite succeed as he planned, but everyone ended up with a partner regardless.
He has pale skin, shaggy hair with black and red stripes and bright pink eyes. His features are strikingly handsome, enough to make any monster girl fall in love with him.
As a vampire he holds the powers of a regular vampire:
Bat Transformation: It is assumed he has his vampire powers already, alowing him to turn into a vampire bat at will.
Blood Sucking: Through his fangs he can suck blood from human beings, like any other vampire.
However, due to his sub-species, an emotional vampire, he holds a lot of powers over the matters of emotions, such as:
Hypnosis: With his pink eyes, Valentine can force anyone to feel love for him.
Misc. Love Spells: Valentine can do several love related tricks, such as flash an heart atmosphere.
X-Ray Glasses: With his special sunglasses, Valentine can analyse the heart of anybody, which he usually does to check out if his victims hearts are or not filled with love.
Love Extraction: Finally, Valentine can extract the love from any full heart, to fullfil his need of love.
Valentine lives in a mansion with his mother, who appears very protective of him. While Valentine likes to act like he's mature enough to act without her interference, he is not and will look for her aid if he loses control of the situation. Adittionally it seems like the relationship is strained between the two, due to his mother's indiffrence over her son's confort by making him live in the garage to avoid the stink.
Three Clouds are Valentine's constant companions and accomplices. They revel in the hurt Valentine causes, but aren't too bothered with laughing about their master's misery if the situation occurs.
Though Valentine has the charms to catch the interest of most girls and the hypnotic powers to grab the interest of the rest, Valentine is only interested in them for their hearts.
