Buzz Lightyear of Star Command 1x23

Mira ghosts into a Crystallic Fusion Generator Core and becomes a glowing, supercharged, power-speed-junkie. Mira's father warns Mira about how her race can fall prey to such temptation, but Mira has to find out on her own. Eventually, after she attempts to battle Zurg on her own, she realizes that her need for ""re-charging"" is getting worse and worse and is beginning to take control of her life, but she manages to overcome her ""energy addiction"".
