Sigmund was an orphan -- up until he was adopted by Silver. He went from being a shy and quiet Riolu to being kind and confident.
He has made it his personal goal to become a master of martial arts, aura, and magic -- a lofty goal, but he works diligently toward it every day with intense training regiments.
Though he has matured considerably since his adoption, he still enjoys being hugged and snuggled, but sometimes he curses being so small. (In those occasions he'll typically just enlarge himself for a while!)
Like his adoptive father, he is, when macro, gentle and doesn't enjoy to harm others.
