The heroes were enjoying being a team for an entire year, and to celebrate, Pinkie Pie threw one of her famous parties. Everyone was there, even the new heroes who joined the force after the final battle with Lucifer. They were all having tons of fun. Ike, Robin, Cyborg, Beast Boy, Sonic, and Rainbow Dash were playing football; Freakazoid was cooking on the grill, even going so far as to have a "kiss the cook" apron on; and everyone else was just resting on the grass enjoying the beautiful day. Phineas and Ferb were sitting against a tree.
"Ferb, I don't think I've ever seen a beautiful day like this before. And the fact that we get to spend it with all our new friends makes it even better. I don't think anything could possibly ruin this wonderful day".
Just as Phineas said this, everyone heard a large explosion coming from the distance.
"Ugh, why did I have to open my big mouth..." Phineas said.
"Hey, what the heck was that?" Rainbow Dash questioned.
Robin answered, "No idea. But something tells me we should check it out. It was probably one of the villains again. Looks like this party will have to wait".
So all the cartoons stopped what they were doing and went together to see what was going on.
It turns out that it had been Thad that caused the explosion. He was attempting to draw the cartoons to him, so he could capture them.
"That should have been enough of an explosion for them to notice. Once they get here, I'll see to it that they are captured like the villains, and then I will rule this entire realm!"
He saw that they were coming towards him.
"Ah, they're earlier than I expected. Oh, well. It's showtime!"
The cartoons got to the area where the explosion was but saw nothing. Thad had hidden himself.
"Well, this is just plain weird" Jenny said.
Cyborg added in, "She's right. Explosions like that don't just happen for no reason".
Just as he said this, a beam of light surged at them, and the next thing everyone knew they were trapped in the same kind of prison as the villains.
"What's going on?" Sam shouted as Thad emerged from his hiding spot.
"Greetings cartoon heroes!" Thad answered. "I didn't actually think all of you would fall into my trap, but boy am I lucky you did! But I digress. My name is Thad Moore, human genius extraordinaire. Now I bet you're wondering why I'm here. Well, the answer is simple. I manged to find a machine that transported me here and my mission is to rule this cartoon universe. I've already captured your villains, so there is no one who can possibly stop me! However there is just one small problem: in order to complete my takeover, I need the seven Chaos Emeralds. I found one in this realm, but the other ones were transported to six realms the video game universe. That's where all of you come in. I will be separating you into different groups so you can each go to the different realms and get the Chaos Emeralds for me. Does that sound good to you?"
Cyborg yelled, "What makes you think we would help you take over the cartoon world?"
Jenny added, "Yeah, and what if we refuse to help you?"
"The answer to that is simple" Thad answered.
He then unveiled a new machine. "If you refuse to help me, then I will destroy the entire cartoon universe and you all with it. So, do we have a deal?"
Twilight Sparkle, speaking for the group, told him, "Fine. It looks like we have no other choice".
"Wonderful!" Thad rejoiced.
He pressed some buttons on his laser and said, "Now this will separate all of you into random groups and send you to the video game realms that have the Chaos Emeralds. The only way you can return to the cartoon world is to use the emeralds' power so you better find them. Good luck everyone!"
Thad fired his laser and all the cartoons disappeared into the video game world.
Once they were gone, Thad said to himself, "Ha. Those fools won't be getting back anytime soon. If they don't find the Chaos Emeralds quickly, then the enemies from each video game are going to tear them apart. Oh, I just wish I could watch it! Well, better begin the ceremony for my takeover!"
