I'd say that Xydane's biggest flaw would be when people get in his way. Whether it's a fight or a personal burden, Xydane's anger and pride tends to get the best of him. Having experience the loss of many friends in past events due to said above, this trait not only hardens the character's drastic emotions but also shows the level for how much he cares for others. He just doesn't show it and would rather curse, yell, and push. This is the reason why he prefers traveling alone and dealing with everything his own way.
