i heard thunder and energy monikers are derived based on some sponsor related to such. well thunder is really asscosiated with lightning, and we all have in mind gatorade's symbol when we hear ligthning. speaking of gatorade's symbol, MegaVoltz was actually a basketball team from the now gone Metropolitan Basketball Association (late 90s - early 00s) in Asia, which had a logo made of the name MEGAVOLTZ (with the letter O symbolizing a running human figure with an angry facial expression as characterized by the sharp triangular eyes & mouth, whose head is a basketball & both hands & feet are made of gatorade-symbol-like strikes) as shown in the link above. i saw a youtube video titled Oklahoma City MegaVoltz
