Thunderous Xavier, whom also goes by the shortened names of Thunderous, Thunder, Xavier, or simply just Xav, is a golden yellow hedgehog of Moebian descent. Though he remained quite loyal to his upbringing, events that transpired after the reign of a corrupt ego-driven king forced him out. He currently resides in a garage warehouse just a few miles shy of Westopolis, where he often works on project cars and fixing up machines for others. Though he's made quite a living off of this, Xav is rather independent, especially so during his upbringing. He refrains from most crowds as he prefers to have his own "living space", and was rather quiet at a young age, not having spoken too much until his adult years. Despite this, those who've known him have stated that he's a well spirited, open-minded being and when approached with others, and is always willing to be of assistance when those approach him for means of help. That being said, he's also known not to fall under any spectrum, as he'd rather not be seen as any sort of hero, as he feels the attention would start to invade his private life. In dire situations however when such actions become important to him, he's willing to make an exception. At times however, he's dealt with the odd bunch that's grown some weariness or even resentment, but often or not has remained rare. Most consider him weak for not being a fighter when dealing with physical individuals, but even he's known to have his limits and can return when provoked just enough. Thankfully, even this is rare as well. His reasons for not being a fighter is that he feels it "resolves nothing... and ruins your clothing with your own blood stains." Similar to others within his universe, Xavier possesses superhuman powers (such as super-speed, a trademark for nearly all hedgehogs). More often than not however, he's not one to show them off, for the sake that he's "never cared about having them, its just a nice bonus." He's also got a large resentment for the "god-modders" who abuse their powers to always have an upper hand, as one of them was the cause of a close friend of suffering near-fatal injuries, a period of which he still remains bitter at the (to not be named) individual who had caused such harm.
Regarding his personal life, with the exception of the aforementioned mechanic as listed above, his passion for cars is undeniably strong. He's much of a collector, and has used the warehouse to stash his favourite machines. His admiration for machines and motor-sports is so strong, that its often joked that Xavier would be able to memorize all the information in about half the time someone else would have just trying to explain it. Other interests is his huge drive for gaming. He was brought to it as a minor, and saw it much of his life as a way to escape from the hectic reality that often surrounded him. In his eyes, he sees it as being able to "play out a fictional world" where his mind can come up with possibilities not even presented by the game itself. As expected, racing games tend to be his favourite. There's always something about going fast in a machine with an engine that always got him the right way.
Those nearby when he works often note that he tends to not only be listening to rather heavy metal music, but can often be seen and heard jamming out to the music. Xavier states that such music to him has been a way of maintaining energy, and as such continues to listen to as much as he can from the genre so he can keep himself in an energetic matter, especially when work starts to drag him down at times. He's also dabbled with more softer rock, and does enjoy the odd bit of dance and drum n' bass music.
Xavier has no known relations or even any recollection of those from the canon universe.
What else can be said about Xavier? Well, one would simply have to approach him and ask. He's always interested in making new friends and accommodates, and is in many ways looking for a good time in one way or another.
