Smallville Season 10 Episode 18 : Booster
While Lois helps Clark to develop a mild mannered persona, Booster Gold shows up from the future to try and take the spotlight from the Blur. Clark confronts Booster and informs him that a true hero is not made by the suit they wear, but by who they are inside. A young teen, Jaime Reyes, comes in contact with alien technology that encases him in a weaponized robotic suit. Unable to control the suit, Jaime begins destroying property and injuring people. Inspired, Booster recounts Clark's words to Jaime and helps him gain control over the suit. Afterward, Clark convinces Booster to mentor Jaime.
