With his limited ability to swim, Chosen One will use what he has to climb back to the surface. It's unknown what exactly he will do, but I'm thinking he'll place his only Cobblestone block as a ledge for him to get up. Next, Chosen One might be able to climb back up to the surface(if his strength is still there) in order to get some help and/or help however he can back at the Rocket Corps HQ.
But then he notices something... or someone, flying high in the sky. It looks to him like an ordinary stick figure got a pair of wingsuits and is able to fly with firework rockets. From there, Chosen One goes on a side-quest to hunt down this stick figure to find out whether he, or she, is a bounty hunter or just a really good fighter. On his way there, he sees the remains of dark red goo surrounding what look to be Shady's glasses. This goo is remarkably similar in colour to the stuff that the Dark Lord was using all those years ago.
From the ALANSPC box high in the sky, he notices victim and what looks to be the Dark Lord working together. "Impossible," the Chosen One thought to himself. "I saw him get killed by Second Coming... how is he alive?" With not much to do now, he hurries over to the woods to hide from the incoming blue and red hues of light, and makes his way to his and DL's old watch-house to rest for the day.
With no powers to speak of, NO ONE attempts a ton of times to rename himself back to The Chosen One, but with little to no avail, since his computation knowledge was limited. Wandering around in the city, Chosen saw what looked to be a purple-coloured stick figure going around town with a pair of wingsuits on his back, hanging out with a taller, older stick figure that was noticably orange, which reminded him of the dangers that would soon commence.
With confidence, the Chosen One went up to them and asked if he could join them. Orange, on the other hand, was against this idea, since he remembers very clearly what happened to his long dead wife Lemon. Purple knows that he was on a wanted poster by the Rocket Corps, but wanted to know why. So, despite his dad saying no, he allowed the black stick figure to sit down with them as they ate some sort of pixelated food, which looked to the Chosen One, at least, of that one game he and Dark Lord conquered.
"Where did you get that meat?" he asked the two.
"We got it from my friend Green," the purple one said. "Why?"
"I was just curious, that's all."
"So, tell me," Purple began, "are you the guy on this wanted poster?"
Immediately, Chosen One was frightened. So, he is a bounty hunter! he said. Stuttering, he said, "I-I-Iiiii am not that guy," he answered.
"He's lying," the orange one said. "I know a lier when I see it."
"Okay, yes, I was that guy. But I had my powers taken away from me, and now a grey stick figure is teaming up with my arch-nemesis, the Dark Lord."
"I knew it." the Orange one said, "you killed my wife."
"I don't even know who you are," Chosen One replied. "Purple... can I call you Purple?"
"I mean... that's what I'm called anyways--"
"Good. You mentioned someone earlier named 'Green.' Are his friends potentially blue, red and orange, like your father?"
Purple looked confused, as he said, "H-h-how did you know?"
"I know everything. I am the orange guy's brother. N-not that orange guy [eluding to King Orange], the other one. Now, I know you must have some history with those guys, otherwise you would not know who they are."
Over at a near building, he sees another wanted poster, this time for Yellow, being taken down.
"Do you know him?" he asked Purple, pointing to the poster
"Wait... is that Yellow? Are the guys in trouble?"
"Potentially. If that's the case, the Second Coming is in trouble, as well."
"The Second Coming?" Purple asked, confused.
"It's my Orange's real name. The name given to him by Alan... I think."
"We should get to the PC fast!" Orange said.
"No. ALANSPC has been compromised. We need something better to hide out at. Somewhere where we can reconvene in peace."
After some silence, Purple says, "I have an idea," with a smirk on his face.
To be continued.
