Jason stepping up to reassure Tommy after they've freed him from Rita's control. Tommy is aghast at the chaos and destruction he's wrought, but Jason assures him it isn't his fault. "What you did, you did under Rita's influence. You own the Power now. We need you." And as the six of them morph together for the first time, they forge a friendship that will last to their dying days.
It's not so much the Rangers' reaction to The Reveal of Tommy as the White Ranger as much as it is Zordon's reaction to their reaction. While everyone (except Kimberly, who's passed out on the floor) is celebrating and welcoming Tommy back, Zordon smiles(!) and chuckles like a father watching his child's reaction to seeing a new bicycle underneath the tree on Christmas morning.
A subtle one for the baddies in "Fourth Down and Long", where Lord Zedd, Goldar, and Rito are playing a game of football. After all their Villain Decay and repeated failure to take over the world, seeing the three of them just hanging out like normal friends was oddly cute.
In "A Zeo Beginning, Part 2", Zordon officially gives the Rangers their new powers. When he gets to Rocky and says that he is now Zeo Ranger 3... Blue... the camera cuts to Billy (who had just given up his spot as a Ranger) and he sighs... and Alpha 5 puts a hand on his shoulder. Even though it was Billy's idea, that moment showed that the finality of his decision wasn't lost on him. For the viewers, that and the later shot of the old Mighty Morphin uniforms in display cases showed that it really was the end of an era, as Billy was the last of the original five.
In an earlier flashback, the Magna Defender reveals that Scorpius (the current Big Bad) killed the Defender's son Zika. To destroy Scorpius, the Magna Defender causes a huge firepit to explode, threatening an entire space colony in the process. Realising what he's done, the Magna Defender heads towards the firepit to neutralise the energy and save the space colony, and there's a scene where he's crawling through a hellish firepit to reach his goal, his armour damaged and cracked, his cape in tatters - when the scene shifts, and the Magna Defender is calmly walking through a field alongside Zika, who is holding a bundle of flowers. Zika tells his father that he's proud of him, and he gives his father the flowers, and the Magna Defender responds by saying that he was proud of Zika, too. The scene shifts back to the Magna Defender crawling towards the firepit - and he's still holding the flowers that his son just gave him.
And in the following episode Magna Defender's spirit appears to Mike, giving him his sword and declaring him to be his successor, telling Mike it's his destiny.
In the finale, Wes' dad has finally shifted from Screw the Rules, I Have Money! to Screw the Money, I Have Rules!. People are being attacked by the Mooks and he jumps out of his limousine, shoves a mother and her kid inside, and yells at the driver to take them to the hospital. The only time Power Rangers has ever made me cry. Actually, all of Time Force's ending, especially Nadira. She and Trip help a mother give birth in the middle of a store, and her amazement leads her to begin questioning the wisdom of her father's vendetta against humans. She asks Frax, her father's recently-imprisoned Starscream, and he finally breaks down and begs her to stop the cycle of hate. She tries to save a child and is accidentally shot by her father, causing Ransik to make a Heel–Face Turn at the realization that he could have lost his only daughter. If he hadn't, he would have won.
The end of "Legacy of Power", the series' 500th episode and a Clip Show framed around a video of the history of the Power Rangers to that point, playing while the current Rangers are trying to find Tommy (who's been kidnapped by the Big Bad.) The scene ends with this:
Tommy (on video): If anything should happen to me, these three (shots of Conner, Ethan and Kira) are charged with protecting the planet.
Kira: That's us!
Tommy: You're in good hands. (video ends)
Conner: He really trusts us.
Hayley: He does.
Ethan: We're gonna have to save him. We owe it to him.
The moderator for the Forever Red panel at Power Morphicon 2016. After someone asked between Samurai and Megaforce who had a worse season, he jumped in and had them skip to the next person in line and laid down the law: he would not let anybody disrespect anyone on that panel or their season.
While the fandom considers those two seasons to be some of the weakest, pretty much everyone agreed that the question was incredibly tasteless.
While he was treated poorly behind the scenes by the crew, David Yost has nothing but kind words and praise for his cast mates and is still friends with pretty much all of them years later.
A good example of this was his panel at the 2014 Power Morphicon where they kept dropping in for hugs and to reunite, Nakia Burrise even commenting that she hadn't seen him since he'd left the show.
Saban airing the entire series on Twitch as one long marathon to celebrate the 2017 film reboot. As of SPD, over 9 million viewers have tuned in, showing that the show is still just as popular today.
The chat's heartfelt goodbyes to Billy during his final episodes, knowing the behind-the-scenes issues plaguing him at the time.
It seems like the long standing animosity between Austin St. John and Jason David Frank has finally ended or at the very least they're willing to be in the same place at the same time now, with them attending the premiere of Power Rangers (2017) alongside cast mates Walter Jones and David Yost.
