|A user on the Khan Academy Wiki|
Light Runner (or Light.Runner.Explorer) is a user who always is on Khan Academy and has over 21,700,000 energy points. He was the first user to name an avatar on KA. He won the contest with the simple, but perfect "Leafers."
He is also known for using a glitch on Khan Academy years ago. But made an apology program and said that he would not put Tesla in his showcase until he got another 6,000,000 points without cheating. He is a bureaucrat/admin on the kausers wiki. Light Runner also has a hashtag going around KA #Lightrunnerspuns which is done when Light Runner posts a pun on any given program.
