Though lacking in charm, one should be wary of this battle obsessed creature. Known for its love of fighting, its interest in strong warriors of all types, there is no fighting style from magical to weapon combat this creature cannot copy.  Though what should be known is that the King of Su will do all it can to avoid dying in combat, not to be mistaken that it would not give its all if cornered or if confident it can win. Rather to the focus that the creature will if it believes no chance will arise, then it will surrender in exchange for its life and give materials or servants it has gathered over the years.

History

The few that know of the creatures origin are said to have been the cause of the creatures origin. Thus though no confirmed information has been gathered, what we do know is that the King of Su was born either in the thrikreen, toth or illithid lands at a young age. As at some point in its life the creature seemed to study and learn how to use its powers to enhance its physical abilities and appearance. Many believe that an illithid that had broken away from its homeland had captured and trained the creature as a pet of sorts. Allowing the King of Su to learn how to use its powers to even greater ability. As the years would go on, the creature was said to stalk the underdark, feeding on any creature it could find. This is where many historians began to believe the creature actually devoured an intellect devourer that was on the presopous of evolving into something strange or unique. And that this is where the King of Su would gain its ability, regardless of its true origin, the creature would travel far and manage to find its way swimming from Crakec to the lands it now inhabits. A young historian would actually document the journey in another book called "King and Me: A love story about Monsters and Dragons", noteably this dragons clan would later fall into scandle for one of there younger members mating with a landerkin or the modern day equivalent of an Oxen on the farm. 
The King of Su would be noted to easily fend off, though unable to kill, the few kracken and other such monsters that attempted to devour it while it made its journey. No historian is quite sure why the creature seemed drawn to such a dangerous land, having done battle with the Lord Mors to take the territory from the creature. There at the time were much easier areas and easier creature to fight, but it seemed as if the King of Su was drawn to combat with any creature it could find that was stronger then it. And while actually not defeating Lord Mors but more tiring the hellfire wyrm out, the King of Su had managed to take the lands he now holds. Fending off the powerful hellfire wyrm in fear of being challenged daily if not outright maning to kill the great ape. 
The King of Su now rules a small town of extremely dedicated fighters, though the creature has little interest, even its own kind that seem to arrive in droves. The King does seem to appreciate the daily challengers and food that he is provided by the warrior like cultists that have formed around him.
