Hoenstly, I think Applejack and Dash ought to switch roles, but then that means you’d need to put in either Big Mac or Rara in Gilda’s place.

@Darth Sonic  
Yeah, they canon’d Bon Bon being a secret agent in the 100th episode.

@Cyborg_pony  
I think it’s supposed to be representative of their relationship.
 
Though yeah, Bon Bon would be the better choice.

Pinkie as Black widow…?
 
I can kind of understand why Dash would be Cap seeing Element of loyalty can translate to patriotism, but that’s an off choice.

@Kurozu  
I actually forgot about the fact that this was a joke about the shared actress.

Who’s the unicorn next to thorax?

Lightning Dust as Captain Marvel.

@Micro-Cyberbrony  
I think the implication is that Pound Cake was the Pietro to Pumpkin Cake’s Wanda.
 
@Darth Sonic  
Tempest could fit pretty neatly into Nebula’s role. And Bloomberg as Groot, while we’re at it.

@PonyPon  
Oh, OK. I just didn’t recognize her.

@Micro-Cyberbrony  
Pumpkin cake, i think.

Question: who’s the orange unicorn with a curly mane next to Thorax?

Celeano really should be replaced with Tempest.
 
Tempest: HOOO~OOOLY SHIT! This a fragging’ HILARIOUS! You’ve been playing one cruel joke on the universe after the other for the longest time, but now? JOKES ON YOU, DICKHEAD! You DON’T love anything! Nothing is real enough for you, not even those supposed observers beyond that wall thing you keep talking about!You don’t love anything, so the Element of Loyalty is forever beyond your grasp! You’ve been PUNKED!
 
The Storm King begins to sob, quite openly
 
Tempest: Holy shit, tears? Really?
 
Queen Majesty: These tears aren’t for him.
 
Tempest: … NO! This isn’t love!
 
The Storm King: Sorry, my dearest Sparky, but I WON’T let the writers fuck me over ever again… Not even for you, Fizzy.
 
Tosses Fizzlepop into the Pit of Loyalty.

|| You should’ve gone for the head… ||

@DR35  
Tirek as Red Skull

If Capper is Star-lord then Catrina will be Ego.

@Background Pony #5266  
You read my mind

And I’ll bet Tempest is cast as Nebula.

Enter a world that’s been flipped upside down
 
If you wake up too fast, you will black out

That looks nice

this will not end well…  

FYI  

@DR35  
I wonder what role Dusty will play.  
Suri might be Justin Hammer.

@genervt  

 
Also Celano as Gamora.

@xemnas14  
Haven’t figure out who are going to potray them

Angel as Rocket.
