History
During his time working with Thresher and Stormer, Von Nebula was known as Von Ness. During a mission in New Stellac City, they encountered a drone which had enough plutonium cryptide to level half the city. Thresher ordered Stormer and Von Ness to stand back while he made a run at the drone. Thresher got knocked out by the drone and was dragged back to the dropship by Stormer. Stormer told Von Ness that it was up to them to stop that drone before it hurt any civilians but Von Ness disagreed, saying they had to wait for backup. Stormer reminded him it could be too late by then but Von Ness didn't care and said he was staying where he was. They glared at each for a moment before Stormer told him to cover Thresher while he drew the drone away from him. Stormer thought Von Ness would do as he was told but Von Ness had other plans and used the dropship to escape and abandon his team leader and Stormer. Stormer landed on the dropship and told Von Ness to bring it down but Von Ness argued, saying he'll get them both killed. Von Ness took off and Stormer fell off
