Hsi Wu

Hsi Wu is a Demon Sorcerer - specifically the Sky Demon - and one of Shendu's seven siblings who were trapped in the Netherworld, making him one of the Demon Portals story arc antagonists.
Jade breifly had a crush on him before she realized he was a demon,
== Appearance ==
Grey, impish bat/gremlin-like demon with a lizard-like tail, Hsi Wu is the smallest of the Demon Sorcerers. 
Though he is still relatively larger than a fully-grown human. 
His human form is that of a small boy the same age as Jade Chan, with hair matching his true form's skin color.
== Personality ==
Hsi Wu can be best described as manipulative and crafty, making up for his smaller size and lack of physical prowess with intelligence and mischief. 
When up against multiple capable opponents (such as his siblings or multiple members of the Chan Clan), he prefers to avoid direct combat in favour of evasive tactics and more wily approaches (retreating to escape being banished and leaving the grunt work to Shendu, disguising himself to infiltrate Uncle's Rare Finds, and stunning his siblings from behind to reach Shendu's Demon Portal first). 
Hsi Wu made two exceptions to this elusiveness rule when facing Jade Chan one-on-one (both times he thought she was unarmed) - the Sky Demon seemingly bore a personal animosity towards the youngest Chan from the moment his cover as "Seymour" was blown, possibly due to her role in his predicament with his tail and later her direct role in his re-banishment.
Hsi Wu was patient in his goals when disguised as Seymour, putting on the facade of a curious and well-mannered little boy - only Uncle distrusted the disguise, commenting that Seymour was much too polite. 
However, after recovering his tail only to discover it had been hexed, Hsi Wu's patience wore thin and he resorted to anger and threats towards Uncle - it got to the point that he nearly threw Uncle from their high vantage point in a rage when the chi-wizard made up one too many in a line of excuses intended to delay aiding the Sky Demon. 
When patience and cunning weren't a combined necessity, as in the above case, Hsi Wu tended to dislike waiting. 
Hsi Wu's limited patience and his love of toying with humans are reflected in his own personal reason for loathing the Netherworld: utter, neverending boredom.
Regarding his relationships with his siblings; Hsi Wu seems to be bossed around and physically picked on by his sisters Bai Tza and Po Kong respectively, to his mild ire. 
Hsi Wu is in turn seemingly something of a nuisance to Po Kong at times, flying around her and perching on her shoulder until she shook him off at one point. 
Compared to most of his other siblings who were anxious to torture Shendu; Hsi Wu seemed to have a more cold and apathetic relationship with his Fire Demon brother - as a result, Hsi Wu seemed to get on with Shendu somewhat better than the rest of their brethren, albeit in curt interactions in which the Sky Demon still expresses some level of contempt for Shendu.
Hsi Wu can be sadistic, true to his family's tendencies; such as when he gleefully taunted Jade Chan and later Shendu with Jade's Moose World camera, and when his disguise's cover was blown and he took a moment to rub the upsetting revelation in Jade's face. 
Hsi Wu is implied to have avian tendencies, as his Demon Chi's effects influenced its human host to create a giant bird's-nest and made her want to fly south for the winter. 
Hsi Wu himself displayed a preference for high vantage points when he was free, and in his royal tower in the Book of Ages-made alternate timeline. 
He despises the sound of the flute greatly, covering his ears and cringing at it.
== Powers, Skills & Abilities ==
Hsi Wu has the ability to fly at extreme speeds. 
He was able to keep up with Jade, who was using the Rabbit and Rooster Talismans at the same time. 
His wings are sharp enough to cut through concrete.
While small in his appearance, he is quite formidable with using flying kicks and his sharp claws to his advantage. 
He was also only momentarily stunned by Tchang Zu's lightning bolts and only took a few seconds to recover. 
Just like real lizards, Hsi Wu's tail is also detachable, which means that he could escape from an opponent's grasp at the cost of his tail. 
His tail appears to possess some form of sentience and will attempt to reattach itself to His Wu when he is in reach.
Hsi Wu is an experienced spellcaster, and he is able to transform into a human. 
In human form, Hsi Wu can partially assume some of his demon body parts without fully transforming. 
Using this ability and his deceiving personality, he can fool almost anyone.
His physical strength has shown to be strong enough to carry a human, as proven when he lifts the weight of Uncle with no struggle and with one hand in a small child's form.
