Since this would most likely take place in Angle Grove High School, Jason would simply confront the guy. Later on it would be revealed by Zordon that GetReady2Fly is actually one of Rita Repulsa's monsters in human form. Jason would be forced to morph and end such evil once and for all.
I always thought it was such bullshit that the White Ranger shows up and Zordon puts him in charge, which was simultaneously a demotion for Jason. It's like, what the fuck, the Power Rangers were undefeated with him as the leader, what's that shit about?
