It starts with Double D letting out a vile war shriek at big bird
Double D: You absolute cretin! You ignominious buffoon!
Big Bird: Shit man no need to get mean
Double D bashes his fist into the ground「Hardware Store」mimics his movements, smashing the ground. The concrete reforms into a wall, and 「Hardware Store」begins to punch segments of the wall, and they fly off at high speed towards Big Bird.
Big bird gestures his bird hand towards the projectiles, and 「Sunny Days」opens a portal, redirecting the projectiles into the wall.
Big Bird: Woah man you need to calm down. You seem really mad. What's wrong dude?
Double D: YOU'RE A RASCAL!
Double D vaults over the concrete wall as Big Bird drew close. He soared above the birds head, and flung a stone he had in his hand. The stone reforms into a razor sharp blade, and slices big bird across the eye.
Big Bird: Gah! You Fuck!
Double D lands, and makes an attempt to dash away, but he's too slow, and big bird picks him up by the throat. Big Bird glares at him with his one eye that isnt logged with blood.
Big Bird: You know, you're lucky you found me so early. With just this stand, you're almost a decent fight for me. That won't be the case for long though-
Double D grabs big bird's arm, and it begins to fall apart
Big Bird: Ahh!
Big bird flings Double D across the room, and before he has a chance to recover, big bird brings a loose chunk of concrete down on his head, knocking him out. As big bird's arm withers and falls off, he summons 「Sunny Days」to spin over D in the same way it did when Eddy disappeared.
Jojo: ZA WARUDO!
The room freezes as Jojo approaches Big Bird from behind.
Jojo: It's a good thing I'm really good at waking up from being passed out. Now let's take care of this poultry.
Jojo winds up a punch, preparing his full weight for one giant attack. He throws his fist-
And big bird moves out of the way, revealing a fully charged portal.
Jojo: What?
Big bird flashes a sinister smile. He plucks the stand arrow out of jojo's pocket, then uses the momentum from jojo's punch against him and pushes him into the portal. It flashes, and Jojo is gone.
Big bird: You really hadn't noticed? Lucky me, I was sure the cubes I brought in from that other dimension to test my abilities would surely give it away. It would seem my guess was right, jojo's time stop only works on things that are from the dimension he's currently in. And I'm not one of those things!
The Time Stop ends, and Big Bird charges his portal once again, disappearing the unconscious Double D.
Doug: Ough…
Big bird turns to see Doug is groggily coming to. The yellow menace makes his way towards Doug, charging 「Sunny Days」once again.
Doug: Why… Why are you doing this?
Big Bird smirks.
Big Bird: Why am I doing what? Getting rid of you and your little friends? It's simple. You had something I wanted, and you were in my way. That stand arrow that you found is rightfully mine. I just happened to lose it in a riverbed. You see, that arrow is just one of many objects of incredible power that exist throughout the omegaverse. I'm going to collect them, and become invincible.
Doug: Why.. Why would you just tell me that...
Big Bird: Idk man im nice. Now fuck off.
And with that, Big Bird activates 「Sunny Days」, and Doug is gone.
