History
Von Nebula was once a hero named Von Ness and fought alongside his partner Preston Stormer to rid the galaxy of crime and villany. He and Stormer often went with commanding officer Thresher due to being young rookies. Some years later, Von Ness was sent with Stormer to New Stellac City to destroy a giant drone attacking the city. During the battle, Thresher was critically injured and Stormer ordered Von Ness to cover Thresher while he fought the drone, but Von Ness betrayed Stormer and boarded a Hero ship and took off. Stormer attempted to stop him, but Von Ness shook him off and escaped the planet while Stormer destroyed the drone. After his escape, Von Ness went into hiding, swearing revenge on Stormer and Hero Factory. Many years later, he resurfaced under the name Von Nebula and hired several villains to destroy Stormer. Nebula sent Xplode and Rotor to Merak 9 and Lemus 2 to steal C-4000 explosives. The duo met with resistance from Stormer and his comrades on Merak, but escaped and on Lemus, Rotor was defeated and captured by Furno while Xplode escaped a second time. Two weeks later, Nebula sent Corroder to Tantalus 5 to sabotage it, but was forced to escape due to resistance from Furno. Later, Nebula sent Meltdown to Mekron City to corrupt Stormer. Meltdown was able to corrupt both Stormer and his friend Chief of Police Drax successfully and escaped, but both were later cured. Later, Von Nebula attacked New Stellac City with help from Thunder, where he revealed himself to Stormer, stating that Von Ness no longer existed. Stormer and Furno ame face to face with Nebula himself who engaged the two heroes in battle, eager to have his long awaited revenge. Stormer grabbed Nebula's black hole staff and sucked the traitor into it towards an unknown fate. Stormer and Furno escaped as Von Nebula's lair collapsed around them, finally defeating Von Nebula.
