Ep 30. Dark Warrior

Uncle Howard, Trini's Chinese elderly uncle, comes to town for a visit. Uncle Howard is an expert martial artist and a brilliant scientist. He has just invented a secret formula which can make people disappear if the liquid is swallowed. He becomes an instant inspiration for Billy, who has unsuccessfully tried to learn some martial arts moves. During a one-on-one discussion with Billy, Uncle Howard and Billy are attacked by Putties. The Putties seize Uncle Howard and take him to a warehouse. He is warned by Rita's Dark Warrior that he has got one hour to tell him where that formula is or he'll be blown to pieces. The Dark Warrior attaches a time bomb to Uncle Howard. Uncle Howard, who can be very absent minded, cannot remember where he last left the formula. In the meantime, Rita has sent the Dark Warrior to destroy the city. The Power Rangers have to race against the clock in order to save Uncle Howard from getting blown to bits. Billy defuses the bomb and frees Uncle Howard in the nick of time. They morph to battle the Dark Warrior. They form the Megazord and with a blow from the Megazord defeat the Dark Warrior. Uncle Howard finds his secret formula at Ernie's Juice Bar and uses it to make himself invisible to play a trick on Bulk and Skull when they go after Billy.
