Idea two, Mischief Bakers. (We need more science fiction and preferably not a parody like this, something completely original)
Pinkmina Pieyear Intergalactic Psycho Cyber Pony G was relaxing in her flying home ship with her perverted professor Sparkle doing some experiment or other. She was happily watching Television it was her favorite show and suddenly she heard crashing and thumping sounds in the other room.
Pinkie tapped a jewel embedded in her chest and white armor popped up all around her body, more specifically to chunks of white armor thickly appeared around her front hooves. With her combat hooves activated she made her way out of the room while the intro to her favorites show was playing.
"My little pony, my little pony, ahhhhhhhh…" The Television was left sitting there alone; fortunately it wouldn't be running for long.
"HEEEEELLLP MEEEEEEE PINKMINAAAAA!" Pinkie entered the next room to find their holes in their house ship and it was falling out of the sky and in the distance she can she professor Sparkle being pony napped by bad guys. Set in her determination she held up a hoof and it sparkling with a glow from the giant blue gems embedded in them, nobody kidnapped her fillyfooler professor and gets away with it!
But seriously her professor really shouldn't be so perverted she was a machine for crying out loud and not a real pony, in fact she was the wrong model of cyber pony that professor originally wanted but got stuck with. Luckily she was a close combat model, as she didn't think the Trix-for-fun cyber pony models knew how to fight and were basically just cute maids unlike her who was being used as a maid, it was rather degrading to her high speed grapple fighting model but she was programmed to protect professor Sparkle by celestial industries no matter how perverted her professor was or how much it irked her artificial intelligence that Sparkle kept groping her, she wasn't that kind of cyber pony model and she was quite straight thank you very much.
She shot out of their falling home before it crashed into ground with her dash jets coming out of her rear end and legs, they'd rebuild it later. Pinkmina's perverted professor was in danger!

Fluttershy was out in the desert planting flowers when a giant headed fire breathing worm jumped up from the ground and threatened her for innocently planting flowers in his desert, Fluttershy started crying as the worm slithered up to her when a voice rang out.
"STOP, YOU NOT FRIENDLY WORM THING! I'm an Intergalactic Psycho Cyber Pony G unit, now you will cease and desist with terrorizing that young populace before I have to cupcake you! My name is Pinkmina Pieyear and if you want me to throw you a party later I will, but you shouldn't be mean to ponies. You got to share and you got to care, it's the right thing to do!" With a flash Pinkmina had appeared on the scene and the worm turned to her white and pink armor with blue gems giving off an impressive display.
"You want to fight then come at me, by the way I HATE PARTIES!" As soon as the large headed worm said it hated parties, Pinkmina Pieyear's eyes turned solid red and her scrunched up hair straightened out and her eyes started glowing red.
From Pinkmina's visual mode on her HUD the words, "That thing is so screwed, activating super bake mode" showed up and Fluttershy watched in horror at what happened to the fire breathing worm next.
Pinkie had grabbed it with her grappling hooves and slammed it into the ground continuously for the next thirty minutes bouncing upwards each time she threw it downwards; she caught it on the rebound every single time seeming to hover in mid air, in what could almost be a permanent loop if it weren't for the fact the worm was getting worse with each passing forceful slam into the ground. Fluttershy continued to wince with each rather painful slam and the blue glow that erupted from Pinkmina's hoof when she slammed the worm again.
When the slamming stopped the worm felt that it was finally over until Pinkmina started shaking it up and down saying some rather disturbing magic words.
"Bake bake, bake bake." The worm was then no more and all that was left in its place when it exploded multiple times before ending in a shower of light, all that was left was a golden cupcake. Fluttershy fainted in the background.

"Boy am I glad to see you Pinkmina!" Twilight appeared behind Pinkmina and groped her with her hooves. Pinkmina didn't like that at all and without thinking her hoof went up under professor Sparkle's throat and her other went to her midsection and with a strong toss she sent professor Sparkle flying into the atmosphere on a low orbit arc.
"HEEELLLLP ME PINKMINAAAAA!" Pinkmina just stared off into space before slamming a hoof into her own face, why did professor sparkle have to go and do that? Why couldn't she just buy a Trix model and be done with it or better yet just build one, she's a cyber pony, magic and friendship expert after all.

Pinkmina was riding on top of Opalescence who was clinging tightly to a missile while Luna and her Cerberus Apple; a giant mechanical pony named Big Mach, were firing missiles lasers and numerous other things in their direction.
()
Pinkmina had Luna's gun in her hoof and she turned to Apple Mach, she shook the gun while shouting her famous magic words.
"Bake bake, bake bake!" A charge started building up in her gun and suddenly it fired a five ton muffin into Luna's and her Cerberus Apples faces, they slowly floated into the air exploding multiple times before going up in one huge explosion, but Luna didn't leave without her final words.
"HOW COULD I… LOSE TO YOUUUUUUU!" With a flash and another golden cupcake in hoof Pinkmina looked towards the future, she knew Luna was being dramatic and wasn't really dead but Big Mach the Cerberus Apple was certainly wrecked.
"You weren't very nice or friendly and I even invited you to one of my parties, but you didn't want to come you big mean pony." With that Opalescence slowed down breathing heavily and a tied up professor Sparkle landed in front of them. By cyber pony laws she was obligated to untie her despite the obvious results of doing so, which would be her throwing professor Sparkle across the landscape and then setting out to rescue her again. Oh well more partying and fun to be had, she used her grapple hoof and the ropes came off magically holding their shape in floating off of Pinkies hoof and professor Sparkle stretched her hooves out before going for another perverted hug. Pinkie threw the ropes to the side and sighed.
End of Idea two.
Final Note: Mischief Makers parody, Pinkie would be perfect for Marina Light-year.
