Biograpy
Gigawatt arrives on Tremorton and starts to drain the electricity of the place. When Jenny battles Gigawatt, she is soon defeated by him after using her plasma ray to attack which Gigawatt absorbed to become stronger. This leads Jenny to use some upgrades that would help her defeat Gigawatt such as covering her entire body with ruber to be invulnerable to Gigawatt's attacks. However, Gigawatt creates electromagnetism in an object to attract Jenny's metal body to it. She later tries different upgrades to take down Gigawatt but fails in all the attempts.

Jenny, her mother, and her friends make a plan together involving teamwork using the previously used upgrades to make a surprise attack on Gigawatt. Gigawatt is defeated afer Jenny splashes water on him which decreased Gigawatt's energy until being reduced to a talking lightbulb. Gigawatt's head is put in a box and imprisoned afterwards, preventing him from draining energy again..
