Choujuu Sentai Liveman has a well-known one: it was the first show to have two robots combine. This is taken for granted nowadays (see Boukenger below) but in 1988...? This was the very definition of this trope.
Choujin Sentai Jetman. After Ako gets infected with a Hate Plague that makes her greedy, Kaori makes use of her immense wealth, buy all the diamonds in Tokyo, then confronts her with an awesomely made-up Rich Bitch voice showing all the diamonds she bought and demanded that Ako snap out of it if she wants to get all the diamonds. Then Kaori administers a Bright Slap to Ako... and it works. Yeah, way to be an awesome rich girl, Kaori.
The latter episodes has Chief Aya Odagiri, after being infected with a Monster of the Week, was mightily pissed off and when the Jetmen got the Jet Icarus drained thanks to said monster, she goes on piloting Jet Garuda alone and completely destroying that Monster of the Week with all of Jet Garuda's moves.
Carranger has an awesome moment where Kyosuke who Zonette hates in his civillian form yet loves when he is Red Racer proves how much he loves her by fighting AND defeating one of the monsters in human form
Hyakujuu Sentai Gaoranger vs. Super Sentai, the 25th anniversary clip movie, is mostly a clip movie of a few of the best moments from the past series. There are a lot of them, too many to list.
Banba Soukichi/Big One (Miyauchi Hiroshi) stole the show. Especially when Banba finally makes his appearance, tossing off his guise as an old, wise priest as effortlessly as a hat, introduces himself in the most confident way possible, then beats down the powered-up Orgs and blowing them into the bay without transforming.
Amamiya Yuusuke/Red Falcon also gets his own moment of awesome, when he ignores a gaggle of Orgs for part of a scene, then explode in rage when their leader puts his foot on the nearby grave of his fallen friend. He then trains Gao Yellow.
The absolute crowning moment of awesome would have to be the mecha fight. After the Gaorangers scramble in their own mecha - and get beaten - mecha from every past series come out of nowhere (apparently lead by Advisor Miura from Ohranger and Shinmei Akira/Aoranger from Goranger - both also played by Miyauchi Hiroshi) and bomb the living crap out of the Big Bad. All to a rousing BGM from Fiveman.
Not to be outdone, all of the clips/remembrances are set to older Sentai music. If you know the genre, this is as awesome as it sounds.
Let's not forget the big rolecall featuring every Redranger from the past.
How could you forget Gao Red?In the movie,he take on SIX Orgs that they defeated (granted,it was an illusion but it was pretty real) and WINNING.He even flip one!Remember,prior to being a gaoranger,he was a vet,while the others at least know how to fight.
The first, when he is forced to morph to save Swan/Kat from a criminal he caught in the past, and wiping out (to a droid) an entire legion of 100 robot baddies who got in his way. The fact that there was an on-screen counter counting down how many baddies were left only added to the awesome.
Then, the following episode, effectively telling his team to screw off and solve their own problems when they started to rely on him to bail them out of the tiniest skirmishes.
Perhaps his Crowningest Crowning Moment of Awesome is in the Cross Over special Magiranger vs. Dekaranger, when he fights The Dragon Wolzard to a standstill and only loses because he can't teleport off. The Island explodes, and he's fine.
Then there's Ban's Moment, when he actually tracked down and physically harassed the SPD Supreme Commander for information regarding the whereabouts of his Red Ranger predecessor after a criminal from the guy's past comes back for another go-around. What makes it even sweeter is not only does Ban not get in trouble for his actions, but his predecessor was so impressed by them, he petitioned and was granted Ban's transfer to a special all-Red Ranger team he was creating. Now that's hardcore.
Task 24 has one, with Natsuki (Bouken Yellow) squashing and blasting a bunch of resurrected mooks with first DaiBouken, then Ultimate DaiBouken. (This also qualifies as a Funny Moment, as the other Boukenger were in the line-of-fire... and Natsuki doesn't notice)
Pretty much the entire second half of Task 28, as the Boukengers put their mecha's arm swapping system to good use.
Satoru parrying Ryuuwon's sword with his Accelluar and then swiping the wheel off it.
Masumi swiping the wheel off the bullets fired from Ryuuwon's gun.
The "Bad Luck" Task has Akashi (Bouken Red) cursed with bad luck. For the final battle, the other Boukenger give him good luck items to help. Though they don't actually work as good luck charms, they do prove useful in battle. While the scene was fairly faithfully traslated into Operation Overdrive, what really sells the scene is the Roll Call.
It's subverted because Akashi looks ridiculous and Ryuuwon and the Monster of the Week spend the whole thing pissing themselves laughing.
Task 42 - Quester no Jidai has a Crowning Moment of Awesome & a Crowning Moment of Heartwarming - in succession. The final duel between Eiji (Bouken Silver) & Gai of the Questers just screamed awesome with the mountain backdrop and the aerial dueling, and the seething rivalry between Eiji and the Questers came to a head in the Task. Bonus Crowning Moment of Heartwarming : Eiji setting grave markers for the Questers after the battle as a mark of respect.
Task 46 - Masumi (Bouken Black) has one of the most awesome comebacks this Troper has ever seen against Yami no Yaiba, one of the main villains of the series. Black's just been almost impailed by Yami's blade, but he gets his second wind and pulls the sword out. Cue Pre Asskicking Oneliner, after which he delivers a devastating beating that kills the guy.
In the penultimate episode, the rangers can't transform. Masumi appears with that series' BFG, which they usually can only use while transformed WITH a super mode attachment. They then proceed to fire it three times into a powered-up monster, the first time sending Masumi flying, the second skidding the group back into a wall, and the third severly damaging said wall. Eiji's reaction in the aftermath to this speaks for itself. Kudos to the actors here.
"A tiger could never beat a lion." "A tiger...WILL NOT LOSE!!!" * explodes with Kageki* * fizzles out like a wasted candle*
...that time. Two episodes later, you get Jan's "I know why I fight" speech and the resulting debut of the Super Gekiranger. The Power Trio proceed to Curb Stomp Rio and minions very thoroughly, with the Super GekiBeasts as an encore... particularly the bit where they summon the other six GekiBeasts for a nine-beast combo attack.
All those moments where the Gekirangers get their asses handed to them by some other villain, so that Rio and Mele have to step in and bail them out, definitely count.
Jan, like a good Red Ranger, gets a few of these, including the above-mentioned debut of Super GekiRed and a later episode where he borrows Ken's Saiblade and then kicks Maku's ass.
Everyone has an incredible one in the second-to-last episode. The show's Big Bad and his right hand man are pummelling the heroes and Rio/Mele. Right when things are looking bleakest, Rio and Jan (Geki Red) deliver an awesome speech that turns everything around. Cue Crowning Musicof Awesome set to the most awesome team fight this troper has seen in years of watching Super Sentai.
Episode 27: Kinggon, one of the current Big Bads, attacks Agri while Agri's going through a Heroic BSOD. Once said BSOD is over, a pissed-off Agri Chou Tensou's into Super Gosei Black and then beats the crap out of Kinggon.
Alata gets a few as well, once in Epic 48 where he falcon punches GoseiKnight in an "I know you're in there somewhere" battle, and in 49 where, after getting the crap beat out of him by Burajira, ignores the idea of using his teammates power (ie sacrificing them to power himself up), runs at Burajira, gets tossed around some more while still giving a rousing speech. This climaxes with him knocking a shot from Burajira away with HIS BARE HANDS.
Toei themselves require a massive amount of kudos for what they pulled with the promos for the first episode of the show. It's something to behold when you one-up yourselffrom two years priornearly eight-fold on the hero front and get ahold of upwards of 175 stunt actors for a promo shot of nearly every single hero in the franchise's history, just about to wage a war against an enemy empire. It's a rainbow of awesome.
The very first episode of the series features the Gokaiger team facing off with an orbiting alien armada set to conquer Earth... and destroying it by drop-kicking it with their giant mecha. It is exactly as awesome as it sounds.
Who says bad guys can't get 'em? When an imprisoned Damaras is offered a second chance after failing to prevent Warz Gil's death, he easily breaks his bonds and the cell door. It's at this point you realize that he could have just walked out whenever he chose, but was punishing himself for his failurenote And it wasn't even his failure. Warz Gil, tired of being seen as the true leader's idiot son, ordered Damaras to stay behind. because he really was that loyal. (Then he goes and shows how powerful he is, completely mauling the Gokaigers, but that scene just makes you say "And he's never done this before now why, again?" You expectThe Dragon to be pretty strong, but it's his loyalty that makes you say "you know, he's pretty awesome.")
