How many times did Tommy lose his powers on the original Power Rangers?

Answer 1

He lost his powers the first time in "Green Candle" 2 part episode. After getting them back, his powers were often weak, and he would periodically lose them temporarily. In "Green No More", he lost the Green Powers for good. Then he returned as White Ranger, and had those powers until the Power Coins were destroyed at the end of MMPR. Then he became Red Zeo Ranger, and had those powers until the end of Zeo. Then he was Red Turbo Ranger, and had those powers until he chose TJ to be the next Red Ranger.

Answer 2

The first was Green Candle, but after he returned in Return Of An Old Friend, he lost it or nearly lost it numerous times, then in Green No More, lost it for good, after one more battle. He did lose it again in the Alien series when their Power Coins were destroyed.

Answer 3

Poor guy lost his power two times. Once, when Rita drained his powers through the use of a green candle formed from some magic wax of some sort. That was part of Rita's revenge, as she didn't want him to join Zordon. Second was when Zedd drained his powers with a green crystal.
