In more recent versions of the character, Garth is also able to direct his electric powers internally so as to move at superhuman speed, with his top speed being approximately one-third the speed of light. Lightning Lad is immune to the harmful effects of electric currents, not only those currents which he himself generates. As a member of the Legion of Super-Heroes he is provided a Legion Flight Ring.
