The Old Weathered One (credited as Weathered One in the end credits) is an elderly weather-changing wizard and a minor antagonist in the Nickelodeon animated series My Life as a Teenage Robot. He only appeared in the episode "Weapons of Mass Distraction" as the main antagonist along with his two henchmen trying to rob banks and valuable items for themselves. He also calls Jenny a "worthy opponent" every time they encounter.
The Old Weathered One is first seen hiding in the shadows ordering his henchmen to rob banks and valuable items as he aids them with his power over nature that he later uses to create a dust cloud that allows him and his men to escape from their first encounter with Jenny. Later on, his henchmen are stopped by Jenny who is at the same time having problems to switch between helping people and hanging out with Travis.
Afterwards, the Old Weathered One makes his last move unleashing a tornado in Tremorton threatening to destroy everything on its path. He taunts Jenny for being unable to stop him for preferring to stay in her date with Travis, who tells her to stop the Old Weathered One. Jenny manages to undo the tornado saving the people trapped in and defeating the Old Weathered One and his henchmen, but at the cost of Travis dumping her in the process.
