Now...the fate of the rest of the missing Crystal Gems should be explained, slowly and one by one.
Peridot, the neurotic green gem, ended up winding on the universe of Mobius, and forging a sort-of unlikely, proper friendship with Amy Rose, a pink hedgehog that took pity on her and allowed her to stay on her home until she found find her way back home. The blame of this could be that Peridot, unwillingly, got one of the all-powerful Infinity Stones stuck on her right cheek before getting on Mobius. The yellow Mind Stone.
In any way, while desperate to find Steven and the others, Peridot also wasn't all that willing to leave her new, pink friend, and even began to share with her how the Stone was giving her visions and weird sensations.
In the current day, a day of rain, Amy and Peridot were in the former's room, Peridot looking out the window with a sensation of nostalgia filling her gem form, and Amy reading a book. Just like in the many months from before, she began to groan in pain, once a wave from the Stone rushed through her gem.
"Peridot?", Amy sympathetically asked, setting her book aside to check her friend. "That's the stone?"
"Yeah...I hear voices on my head now...", Peridot replied.
"I hope we can understand for once what is happening...", Amy said, with hope, as she hugged her smaller, green friend. "And I'm sure Sonic will help!"
"...yeha, this. Sonic guy, will help?", Peridot said, kind of awkwardly; it wasn't the first time in those two months that Amy mentioned said legendary, blue hero of Mobius to her. She groaned again of pain, forcing Amy to break the hug. "It's stronger now...what if it's here?! Come on!", she said, running outside. Amy ran outside as well, but not before getting a more cold-appropriate attire and her weapon, Piko Piko Hammer.
They ran, checked out even far from Amy Rose's home...but nothing. For now. Only a space with brick-like, brown rocks and grass between them.
"*groans*", Peridot says, preparing to say something. "Amy, I-"
She is suddenly wrapped by painful, spiky vines that just didn't poof her physical form because of her physical toughness. The one responsible for this was Mary, the painting, one of Zalgo's Followers.
"Peridot!", Amy yelled in panic, as Peridot was thrown away, weakly. She immediately drew out her hammer to attack, but the Beldam, the last Follower of Zalgo, picked her up and threw her agains't a wall.
Meanwhile, Mary drawed a knife and stabbed the area where the Mind Stone was stuck on, and Peridot screamed in pain. Now, she wasn't the strongest of the Crystal Gems, but her durability felt miserable because of the knife's might. Amy threw her hammer at Amy and kicked out the Beldam, before running away, carrying her green friend by her feet and not paying attention over her recieving hits from incoming rocks.
"Are you ok?", Amy asked, in the middle of pants.
"Yeah...not really.", Peridot snarked as she inserted her hand protectively over the Mind Stone. "We should have stayed home today."
However, a vine separated Amy and Peridot from each other, forcing them to fight the Beldam and Mary respectively.
Amy held her ground quite well until she was knocked down, while Peridot used her wits and above average resistance to "fight" agains't Mary. She tried to use her control over metal to pick Mary's knife and attack her with it, but due to lack of experience, Mary easily recovered it.
Peridot accidentaly ended tapping on the power of the Mind Stone, making a forcefield that forced Mary to use her spiky vines to try and break though. This gave Amy enough focus to give a low blow on the Beldam's needle legs.
Sadly, Mary broke the forcefield, and Peridot was thrown with a high-pitched scream upwards, like a tennis ball. Amy rushed for her dizzy friend's help.
"Come on! We gotta get out of here!", Amy said to the dizzy Peridot, rushing with her last energy towards to the farthest she could from the two villainesses. "You can't leave me hanging, not now!"
As Amy caught a break to breath, Mary and the Beldam quickly arrived, prepared to shatter Peridot and put a end to Amy's race. But before it could actually happen, a sequence of events fast enough to be lost with a single blink began.
First, a spear of spiral-design with a star on it's handle tried to fly at the Beldam's head, and she, of course, picked it up. Then, a blue blur rushed in, covered in the shadows thanks to the hills. The Beldam threw the spear at the figure, only for the figure to get it lightly crooking his upper body to his left and using his hands.
As the Beldam stepped back in disbelief, the figure stepped forward, to reveal it was none other than Sonic the Hedgehog, hero of Mobius and the First Hero. Now, the blue fur in his spikes had some darker hints, and he was wearing a old scarf, but his serious expression quickly shifting into a confident smile didn't trick off anyone.
Amy gasped in joy, over seeing her dream-y crush and friend back in action, ready to rescue them, while Peridot looked with surprise over meeting said legendary hero of Mobious for the first time.
Before a proper reaction from the female Followers of Zalgo could be shown, a flying kick hit the Beldam agains't one of the rocks; it came from Lapis Lazuli, the blue reluctant new member of the Crystal Gems with destructive water powers and wings. She transformed one of her wings into a large fist to try and punch down Mary, who blocked it with ease.
Sonic threw the spear seemingly at nowhere, only for it to be given back to it's rightful summoner; Pearl, one of the founding members of the Crystal Gems, beyond being their brain. Pearl caught the spear and fighted with grace agains't Mary, dodging the painting's blows before stabbing her in the stomach.
However, a spider sink stole Pearl's spear, which felt into the Beldam's hands. Sonic quickly stole Mary's knife and used it as a shield agains't the Beldam's offensive attack. The two weak, but fast fighters, parred blows from the button-eyed spider witch, giving Lapis time to kick her in the face and knock her out of battle, right next to a injured but tough Mary.
"Get up...", the Beldam tasked.
"I can't...", Mary said, in a voice trying to hide pain.
"We didn't have to fight. But if you want...", Pearl calmly stated.
"You'll never get another chance.", the Beldam said, right before being beamed alongside with Mary to one of the O-ships from Zalgo's army. It quickly left Mobius, went to space and presumably to their next destination...
"...are you alright?", Sonic sympathetically asked Peridot, who needed her friend Lapis' support to properly get up.
"Eheh...thank you Sonic...that's your name?", Peridot asked, as all the panic and fighting and adrenaline made her forget. Sonic's reply was a quiet but positive nod with a smile, as he guided the others to a titanic ship, of pink colors and shape of the lower body until the legs.
"I sincerely though Peridot shouldn't be getting in trouble...", Pearl mildly and indirectly scolded her fellow, forehead-located gem. "...but thank you for taking care of her."
"No problem...", Amy blushed.
"Where we'll go?", Lapis calmly asked, as Pearl took control of the leg ship, and she and Sonic looked at each other, settling for a answer.
"Home."
