Months after the Rifts Closed...
Peter and Twilight lay peacefully in their beds. Months have passed since the heroes of both Earths went back to their worlds and for the first time since Miguel showed up, Peter was back to being the only Spider in Equestria. He moved around, his memories triggering a nightmare he knew all too well.
He floated down a black abyss, seeing images of his friends, family, those he had parted with from the Earths. His eyes fluttered open, finding himself falling headfirst. Getting his bearings, Peter flipped himself around and landed on a purple stain-glass painting now transformed into a human. Images appeared in the void again, showing him Future Rainbow Dash, Future Trixie and Future Applejack perishing during his time in the future to the death of Gwen once again, haunting his mind.
Peter saw a bright light overtake the blackness of the void before the nightmare could continue, changing the image of the stain glass window he stood upon from Twilight and the Elements of Harmony into a picture of himself standing on the center, with five other figures surrounding him in smaller circles. He recognized some of the people while the rest looked somewhat unfamiliar.
'Peter...'
"Huh?" the voice snapped Peter out of his trance, "Is this the same voice again? The light is new."
'No... The nightmares you face must be overcome on your own. I am here to deliver a message.'
Turning around, Peter noticed that he was in his Spider-Man costume. He immediately saw the hooded mare, a stranger to him. But even he could tell she was powerful. "Okay. So, do you want to introduce yourself or should I just accept that I've gone insane?"
'Do not worry, Peter. For my visit is merely temporary. You may call me Solar. And I have come to this world to bring you a warning of dark times ahead.' Solar introduced.
Crossing his arms, Peter looked at the mare, "Hm. Dark times ahead? Again? Look, Solar, I've dealt with enough already. What threat is coming this time and why are you warning me Madame Web style?" he wondered, a little confused.
Solar bowed her head, 'My apologies for bringing this upon you. But I have been travelling to different Equestrias. Meeting different heroes displaced from their worlds. You may recognize some of the people in the portrait we are standing on.'
Peter looked down, taking a closer look at the images, "Hm. Yeah, you're right. I see Batman, and Mega Man. Some green guy with a red mask, I think I've seen him. And I think Rock told me about the guy in the red hat, and that blue spiky thing. Yeah... What does this have to do with me again?"
'The six of you represent something, Peter: Determination, Confidence, Purity, Hope, Trust. They are like the Elements of Harmony, but have a different aspect, and they are different versions of heroes you have met with their own experience in Equestria as well. You, Peter, represent Responsibility and Harmony. The six of you shall use these traits if it means bringing down the foe who can destroy everything. My biggest mistake for a hero to summon...'
Peter raised a brow, "And who may that be exactly?"
Solar lit her horn, changing the stain-glass window once more. This time, it changed into the image of a green-hooded person wearing a metal mask. Recognizing the figure, Peter clenched his fist, knowing who the threat is now.
'He is an old foe of yours. Doctor Victor Von Doom.' revealed Solar, 'He is in my world and has formed a Cabal with five other malicious beings from the worlds of those heroes I have chosen. He believes what he is doing is right, but the end of all may come to pass.'
"Doom?!" shouted Peter, "Johnny mentioned he vanished... So he ended up in an alternate Equestria!?" seeing Solar nod, it made Peter worry greatly.
"How is it that he can bring the end?" Peter asked.
Sighing, Solar gazed at the ground, 'There is an organization in my Equestria that seeks to manipulate Doom's Cabal into furthering their goals. You, the Warriors, must convince Doom to change his ways, even if it means going against his organization before facing the group that seeks destruction.'
Silence passed between the two until Solar cleared her throat, 'Are you willing to aid us, Peter? You have been in Equestria longer than the other heroes. They can use your experience. We will leave once the last member discovers himself, then I will bring you to summon him as he is fighting Doom right now.'
With a defeated sigh, Peter answered, "Yes. If you need all the help you can get, especially against Doom, then I going. If I can, I'll make sure that Doom doesn't get too crazy."
A smile was seen on Solar's muzzle, 'Thank you, Spider-Man. I shall now awake you as the sun is rising. We will meet again...' she faded from Peter's mindscape and left Peter with a good rest for the first time in a while.
Waking up, Peter noticed a hoof wrapped around Twilight, who slurred awake. "Peter...?" she moaned.
"Hey, honey. Slept well last night, sorta." revealed the stallion.
Opening her eyes, Twilight gave him a confused glance, "And how is that?"
"Oh man, how do I explain? Well, basically a strange being from another dimension recruited me into a team and wanted me to help fight against Doctor Doom and a league of five other villains. Batman is gonna be there as well as Mega Man. Though, I'm not sure if you would let me or when it is."
Twilight frowned, it was true she wished that Peter and her could enjoy the peace, but she knew his motto and a soft smile appeared on her muzzle, "Go, when she needs you to go. I know you'll make it back." she comforted.
"Thanks, Twi. I just thought you should know." he kissed Twilight softly, finally getting up from the bed, "But explaining things to Mayday may be a little harder."
"I'm sure she'd understand."
