Rainbow Island (Bubble Bobble)

Knuckles walks up to Bubblun and Bobblun.
Knuckles: Who's this "Dark Dragon" guy?

Bubblun: We fought him while were humans. He turned our friends and the villagers of Rainbow Islands into Bubble Dragons, and he prisoned them in his darkest world.

Kunari: But do you know where that guy is?

Bobblun: He's at Rainbow Tower. Some meteor falls from the sky and crashed into the tower. It woke him up from his slumber and takes it. He gained power from it.

Bubblun: Now the whole island is doomed unless there is a miracle.

Knuckles: We'll take him down, especially if that "meteorite" is what I think it is...
Knuckles heads to Rainbow Tower.

*SGDD blasts dark bubbles at Knuckles*

SGDD: You dare battle the mighty Super Great Dark Dragon?! You pitifiul little thing can't destroy me this easily. I am more powerful than you. I am invinsible!!

Knuckles: Yeah, right!
Knuckles throws a boulder at SGDD.

*SGDD destroys the boulder with his claws*

Knuckles digs underground.

*SGDD then smashes down the ground, creating an earthquake*

Kunari: Knuckles could've been stunned while underground!!!

Bubblun: That's it!! Let's show that giant monster what we're made of! If we can defeat him once, we can do it again!! *enters Rainbow Tower with Bobblun*

SGDD: Well well, Bub and Bob... What a humble surprise.. You two twerps have grown so fast, I forgot who you are!! But your future will be terminated once my revenge fulfills!! Once you're out of my way, I will take over Rainbow Island, and fill it with pure darkness!!!

Bobblun: You'll never get away with this!!

*Two giant electric bottles appear as the two bubble dragons grab it. They shoot thunder bubbles at SGDD, damaging him a bit*

Knuckles comes back up to the surface, innured.

*SGDD launches a giant bubble at the trio like a cannonball*

Knuckles jumps out of the way.

*Bub and Bob does the same*

SGDD: Puny creatures. You are no match for my strength!!! *flips up further*

*Bub and Bob shoots electric bubbles at SGDD, damaging him a bit*

Knuckles throws more boulders at SGDD.

*SGDD hits them, but missed one and took damage*

Knuckles spin dashes SGDD's foot.

SGDD: OW! MY FOOT!! Why you.. *grabs Knuckles and squeezed him hard, then throws him at the wall.*

Knuckles wobbles around with spinning eyes.

SGDD: Anyone else wants a piece of this?!

Bobblun: Never!! *shoots electric bubbles at SGDD, damaging him a bit*

Knuckles starts to get his senses back.

*SGDD roars loudly*

Knuckles fully gets his senses back and glides up to SGDD's head.

SGDD: Pesky echidna!! Get off!! *throws Knuckles away.*

Bubblun: His weakspot is his chest!

Knuckles: Got it!
Knuckles glides up to SGDD's chest and punches it.

SGDD: NAAAAAAAUGGHH!! Meddling Bubble Dragon! *Blasts a cannonball bubble at Bobblun, knocking him out*

Bubblun: Bubby!!

SGDD: Now to destroy you once and for all!! *slashes Knuckles away*

Knuckles falls back down to the ground.
Knuckles: Ugh...this is pretty hard...
