Rage Shenron Character Facts

Rage Shenron can be described as arrogant and power-hungry. Under the delusion of being the most powerful of the Shadow Dragons, he believes himself invincible. These traits prove to be his greatest weakness, as his obsession with power and desire to be the best lead to both his defeat in battle as well as his death. 
Just like the other Shadow Dragons, Rage Shenron is born from the negative energy that resulted from the overuse of the Dragon Balls. He was specifically born from the wish used by Master Roshi to resurrect Goku so that Goku could fight against the invading Saiyans Vegeta and Nappa.
Rage's powers and skills are solely based on electricity. As such, the only way for him to defeat his opponents is to deliver a strong enough electrical discharge so that his victims are shocked to death. As a result, the effectiveness of his abilities are limited and strong beings such as Vegeta and Pan are able to withstand the hits without feeling more than a slight numb on their whole body. Due to this, he is one of the weakest dragons, being probably comparable to Naturon Shenron and barely any stronger than the weakest of the group, Haze Shenron.
