This is how Finding the Allspark and Megatron breaks free goes in My Little Pony Transformers.
[We then see Starscream fly up to the dam and fire off missiles]
[The missiles hit important parts disabling the security system]
[The systems begin going down]
[We then see the others]
Secretary of Defense: Gentlecolts. They know the Cube is here.
Deathstroke: [picks up a phone] Sector E, what's going on?
Sector E Pony: The system to keep NBE-1 has gone down, sir.
[We then see Frenzy in the computer room, having killed its occupants]
Frenzy: [accesses a computer to unfreeze Megatron] [excitedly] Megatron! Megatron! Megatron!
[We then see some people in the freezing chamber struggling to keep Megatron frozen]
Pony on PA System: Attention! We are losing NBE-1! We're losing him! We're losing him!
[Cut to the group leaving the testing room]
Deathstroke: Get everyone to the armory and garage away from the NBE-1 Chamber, now!
[They make for the garage and armory]
[Inside the armory/garage, Thunderbolt, his team, and Discord load up some of their weapons]
[As the lights flicker, Rarity goes over to Discord]
Rarity: You have to take me to my car.
Rarity: You heard me.
Discord: You're car? It's been repossessed.
Secretary of Defense: Discord.
Secretary of Defense: I'd do what he says. Losing's really not an option for these guys.
[We then see Bumblebee walking up to the Allspark and shrinks it]
Rarity: That'll do.
Bumblebee: Message from Starfleet, Captain.
Captain Thunderbolt: He's right. We're going to have to get that thing out of here. Mission City's not that far from here.
Thorax: That's way too close. And they've already had enough alien attacks for one year.
[Discord nods in agreement]
Discord: Las Pegasus is just as close. Get the Cube there.
Secretary of Defense: Good right.
Captain Thunderbolt: Let's go! Let's go!
[Bumblebee transforms to vehicle mode]
[Twilight and the others get in and drive off]
[The soldiers make their way to the other garage]
[Back in the computer room]
[Frenzy continues typing when he looks up]
Frenzy: Oh, Megatron melting.
[Megatron is then seen breaking free of the ice]
Megatron: I am Megatron!
[Megatron activates his flail and swings it around]
[We then see Bumblebee, the Mane Six, Thorax, and Thunderbolt's team leaving the dam]
[Back in the freezing chamber]
[Megatron swings his flail and transforms to Cybertronian Jet Mode and flies out]
[Starscream transforms to Jet Mode as Omegabot transforms to Combat Plane Mode]
[Starscream and Omegabot transform to robot mode as Megatron lands]
Starscream: We live to serve you Lord Megatron.
Megatron: Where is the Cube?
Starscream: The ponies have taken it.
[Megatron clenches his fist]
Megatron: You fail me yet again Starscream and Omegabot. Get them!
Omegabot: Forgive me, my lord. [transforms to Combat Plane Mode and flies off]
