Honestly, we all knew the season was shit, so here's my version of an extended ending for Super Megaforce.
...
The rangers lay on the ground, having won the battle with the Armada. The get up, Gia kisses Jake on the cheek, the 5, minus Troy, start walking back to their city. Troy pushes thee sword into the ground & joins them then they run back home.
A hand comes in frame & grabs the sword. he camera turns to see a red-jacketed Japanese man pulling it out of the ground.
Translation:
"Hmm. I hope that bastard, Gosei, had fun stealing our powers 'cause it's never going to happen again," he pulls out his mobirate. "Doc. You got the Galleon?"
"Yes, Marvelous. Bringing it around now," Doc says, as Marvelous looks up & sees the Galleon come overhead.
"Roger that. I'll be up in a second then we'll go home," he pulls out his ranger key.
"Gokai Change!"
Gokaiger!
He then reaches out & grabs on to the rope coming from the Galleon & it pulls him up. He enters the main bridge & greets the other Gokaigers.
"You guys ready to go back to our universe?"
They all nodded in agreement.
"Alright, let's go!" he says, as they put the mystic ranger keys in the key holes & they turned them.
A dimensional portal opens up & they started to enter it. The scene turns to Gosei & Tensou in the command cave.
"There they go, Tensou."
"Yes, Gosei. it was nice of them to lend us their powers."
"Well, after we found the mystic keys her in our universe & contacted them, it was a simple means of trapping them & stealing their gimmicks. We let them out & gave them back their Galleon & stuff after we were done using them, so now they're going back to their universe. How are the keys by the way, Tensou?"
"Well, Gosei..." he turns on the lights around where the keys were to check on them. "They're gone!"
"What!? Where are they? Check the surveillance tapes."
"Checking, Gosei," he looks at the computer monitor. There was a moment where the keys were there, then a Flash-like streak zips through & all the keys vanish from sight.
"Slow it down, Tensou."
"Right," he slows it to frame-by-frame to see what happened. They then see the back of a red ranger suit.
"He used the RPM powers to steal the keys."
"How?"
"He must've had his universe's counterpart's key & used it to swipe the keys. Quick, contact the rangers & have them use Gosei Great to stop them!" he says, but when he sees the universal portal, it fades away. "NOOOOOO!" they then hear a ticking & see a bomb under a console that ad one of the ranger's colors on it. "MARVELOUS! Quick, Tensou, get the mystic keys."
"Right, Gosei," he looks in the secret compartment, but sees that they're not there. "They're missing!"
"MARVELOUS!" the bomb exploded & the command center was laid to rubble.
It turns to Marvelous smirking on the Galleon.
"Hope he likes that present we gave him. He really deserves it," they all laugh. "Now, on to finding even more legendary treasures! Let's make it showy!"
They all sat in their seats, as they sailed off into unknown space, looking for adventure. The scene peers to the treanger chest, opened that has all of the keys in it that Marvelous stole.
...
Well, that's my send off to Super Megaforce. Ultimately not worth it & should've been more like Time Force, or Wild Force. Don't kid yourself. It was AWFUL. See you guys later.
