Summary
Metal Sonic remembered something he was not supposed to remember. Suddenly, everything came crashing down. He knew what he used to be, but what was he now? He did not know.
It was a beautiful, spring day for Amy Rose and her friends. They all sat in the park having a nice picnic when they discovered Metal Sonic lying face down in the grass. He was badly damaged, and completely inactive. Seeing him like that broke Amy's heart. While Tails spent weeks repairing him, she visited as often as she possibly could. She made sure Tails got the necessary rest, of course. When she and Metal were alone together, she would talk to him. She told him stories about her favorite adventures, and the ones she didn't enjoy so much as well. She told him the plots to her favorite movies, the lyrics to her favorite songs, and really anything she could think of to tell him. From that point on they would only grow closer.

Summary
In the Upheaval, Link and Zelda won the day, but they came out changed for it. Zelda is now the Dragon of Light, and even if she's regained Hylian form, she still has the horns, tail, and scales of a dragon. And Link has the arm of a Zonai, one that enables him to use strange powers of fusion. Zelda has a theory that Link hasn't fully tested the limits of what can be infused with the essence of a monster part and how that might be used for the reconstruction of the Kingdom.
It's definitely for the reconstruction of the Kingdom. And science. Rebuilding Hyrule and science. Certainly not any other desires Princess Zelda might have...

Summary
A year after the “Gentle Ruffians incident,” the Powerpuff Girls Z are still clocking in for hero duty—school by day, butt-kicking by… also day. But echos of the fallen boys won’t stay whispers; whispers echo through New Townsville and their heads like a bad ringtone. And before anyone can say “suspicious plot beat,” the boys slip back into their lives—messier, moodier, and more complicated than ever.
Meanwhle, Mojo Jojo, who has learned approximately zero lessons. Determined to outdo the Rowdyruff Boys (and his own résumé of poor choices), he taps into the same weird energy that birthed the Gentle Ruffians to cook up a new menace: a sinister mirror of the Powerpuff Girls Z. Now the girls and their allies must face their most unsettling enemies yet—themselves, twisted. It’s like staring into a funhouse mirror that also wants to punch you.

Summary
“Guess he is a chao.”
Tails’ left ear flickered. He snorted, “This is how we are calling chaos users now?”
Sonic opened one eye. He gave a lopsided smile, “Why not? It portrays the message and keeps things incognito. It fits just fine!”
Tails blinked. Then blinked once more. He then shook his head. Sonic did have a point even if the name was ridiculous. Cream would have loved it though if she were to ever find out.
But they couldn’t share this yet. Not to anyone. They would have to see what to do with the A.R.K soldier first. They kinda just pull him into this mess without being sure if he wanted to. If he didn’t have Sonic’s vote that he didn’t pose a threat, Tails would have already put him in a cell despite his current fascination with his chaos powers.
The kit pinched his temple. That was too much to unpack in just one day.
~~~
Set in a dystopian era, ARK is the force monopolizing Mobius, threatening to turn it into nothing but metal. When picking up the signal of a legendary gem, however, Tails and Sonic meet a dark hedgehog capable of tapping into the gem's powers.Perhaps, he is the miracle they had waited for. If only he wasn't dressed in the enemy's garments.

Summary
Metal Sonic, Eggman's greatest machine, has always been... strange. Maybe it's the fact that he doesn't really know where it came from. Or maybe it's the part where it seems to have a mind of it's own. What no one knows, is that Metal Sonic was never a robot to begin with.
Or...
Some people will become a villain just to finally feel love. -

Summary
Espionage was always Espio’s strong suit.
Whenever a case required more information that could only be obtained through infiltration, he was the one sent in. So, when his team’s latest mission was to investigate an anonymous tip from an unknown client, he was sent to check it out.
The claim had been believable enough. One of Eggman’s old factories from the war had been reportedly seen active again, gray clouds drifting up from the smokestack every so often. Their client had asked for them to go investigate. It was a concerning case. The factory had never been cleaned out post-war. No one wanted to enter and relive their trauma so early into peacetime, so the idea of a new criminal having access to Eggtech… It practically spelled out trouble.
OR:
After the success and subsequent failure of the Metal Virus, Eggman decides to attempt to refine his process once again. Armed with his new technology, dubbed the Roboticizer, all he needs is one thing; a test subject, to be sure it works. And who better to test it on than an unfortunate Espio, captured during an investigation of a supposedly abandoned factory from during the war?
