(Lugia fires Aeroblast attack and hits the huge rock saving the heroes from getting crushed)

Kim Possible: Target on sight. Prepare to destroy the computer.
(As Kim prepares to shoot the mind control computer device, suddenly a thunderbolt attack came out of nowhere and hits the left wing of the plane and goes down)
(G-Merl goes down to save Kim from crash landing)
G-Merl: (Grabs Kim Possible) I gotcha!
(G-Merl flews off with Kim as her plane hits the building and explodes)

(Then we see Rigby running to Mordecai)
Rigby: Mordecai, did you find the...
Mordecai: Yes, and we got problems.
(They see Mr. Ross aiming the gun at them)
Mr Ross: You guys, we got to stop running into each other like this.
Mordecai: Step aside, Ross.
Tino Tonitini: Your plan of controlling all Legendary Pokémon must be stop.
Sunset Shimmer: You are never gotta get away with this!
Rigby: Yeah! It's time to finish this.
Mr. Ross: We'll be finished when all Legendary Pokémon will be ours forever and you two and the rest of the heroes are dead!
(He fires the gun as Mordecai & Rigby duck and cover)
Mordecai: Stay with the plutonium!
(Mordecai charges to Mr. Ross)
Rigby: AHH! Mordecai!
(As Mordecai starts beating Mr. Ross, the gunshot breaks the bridge and it breaks another one)
Mordecai: You are the worst teacher!
Mr. Ross: Stuff it!
(Mordecai bit Mr. Ross, as Mordecai beats Mr. Ross up. Mr. Ross got up and gets shot from Rigby holding a gun. Mordecai looks at Rigby)
Mr. Ross: Yoo - Hoo. (hits Rigby, and he laughs and teleports)
(Mordecai gets punched by Mr. Ross)
Mordecai: Show yourself.

Mr. Ross: I've been waiting a long time for this!
Rigby: I'm sorry for ruining your dumb volleyball game, okay?! Just let it go, man!
Mr. Ross: "LET IT GO?!" Do you know what it feels like to dedicate your life to something and then have it ruined?!!
(Rigby looks at Mordecai)
Rigby: Yes I do. But I'm gonna work hard to make it right! Mordecai, NOW!
(He runs to Mr. Ross pushes him and Rigby traps him and then Mr. Ross falls to his death. Rigby helps Mordecai up)
(Reshiram, Zekrom Lugia, Latios and Latias showed up, and the others gets off)
Donatello: You guys alright?
Skips: Whoa, is he gonna regenerate?
Twilight Sparkle: I'm not sure, I think that fall must have broken his neck collar.
Raphael: Let's do what we came here to do.
Princess Luna: [echoing] It is time for you to face your real fear, G-Merl!
G-Merl: [sighs] Wait, I need to say something. (to Sunset and Tino) Sunset, Tino, this is all my fault. If I haven't try to break you two up, it would have made thing's more different for me, I didn't mean for any of this to happen.
Bonnie: Well, I think she had it out for you anyways.
G-Merl: It doesn't matter, Bonnie, [To Sunset and Tino] I robbed you and Tino with your future cause I was being selfish, You're the only girl I ever met and I couldn't stand the thought of losing you, I held you back and ruined your life, and I'm sorry.
Yoshi: Dude, you didn't ruin her life. What you did was messed up. But I think before she was putting too much blame on you for how things turned out.
Mordecai: Yeah, Rigby and I made plenty of mistakes on our own for sure. And if you didn't do what you did, maybe things would have been different. But I take that saving everyone and the whole universe with our best friend, any day.
Sunset Shimmer: I understand, and going by your own experiences, we'll forgive you.
Rigby: Hmph. Hmph-hmph-hmph
Mordecai: Hmph. Hmph-hmph-hmph.
(Gmerl goes to the box of plutonium)
G-Merl: Now get out of here and stop the villain's, I'm going take care of Dialga and Palkia on my own.
Mordecai: G-Merl, no! You don't have a protective suit, you'll die!
G-Merl: I'm tired of you always fixing my problems, This time I'm going to fix it!
(G-Merl activates his cyclone blaster)
G-Merl: TAKE THIS, CYCLONE BLASTER!!!
(Dialga uses Flash Cannon and Palkia uses Power Gem as the attacks collide)
Twilight Sparkle: No!
Skips: Come on! We've gotta go!
G-Merl: Hey Tino, one more thing! Saving the world is the best thing I've ever done. So if you can get Celestia to make a sweet bronze statue of me to put at the front of Canterlot, that'll be really cool.
Tino Tonitini: G-Merl....
Twilight Sparkle: NOOOO!
Yoshi: We have to leave him!
(Dialga and Palkia used full power as Gmerl fell on his knees)
Skips: It's too late!
Twilight Sparkle: NO IT'S NOT!
(She pushes Skips away and goes to help G-Merl)
G-Merl: (Grunting) Huh, Twilight, what are you doing?!
Twilight Sparkle: I 'm not going to just stand here and let you do this by yourself. I want to be part of the statue too.
(Dialga and Palkia try to attack G-Merl and Twilight, but then a beam came out of nowhere and hits Dialga and Palkia and frees them being mind controlled)
Ash Ketchum: Don't worry, they got this.
(It was Mesprit, Uxie and Azelf who free Dialga and Palkia from being controlled)
Sora: Nice one, Ash!
Yoshi: Way'd a go!
(Then Primus and Galvatron appears)
Primus: The game is not over fools!
(Optimus Prime came by and fights Galvatron)
