Silver is best described as having "a strong sense of justice" and it is this personality trait that motivates him to help Sonic and the others against Utonium. He also believes in standing up for those who can't stand up for themselves. Silver has a strong sense of justice and will usually do whatever he can to help protect others. He's on good terms with Sonic and the Mario Bros and he seems to respect Shadow as a powerful rival and ally. Although seemingly serious in nature, an interview states that Silver is young and somewhat immature.When Silver is not focused on his current mission or does not have a task at hand however, he is very friendly and a good company to have around.
Silver can use psychokinesis/ESP, so he can lift or throw people and objects tremendous distances with great force. He can also use it to make himself levitate and paralyze his targets. Like Sonic and Shadow, Silver can use Chaos Control and has a Super Form. Apparantly, he also has the ability to time-travel, but he rarely uses it, due to it's drain on his stamina.
