Max Tennyson: You've all became part of something bigger.
Ben, Gwen, Kevin, Danny, Dani, Valerie, Mark, Aang, Edd, and Whitley all stood in the streets of St. Louis as they see Dan Phantom, Danny's evil future self floating above the city with an army of alien creatures known as the Covenent, landing into the city and opening fire at civilians.
Max Tennyson: You ten just haven't realized it yet.
Spectrum, Stormwolf, and Icewolf are seen on a mountain facing off against a mountain of a monster.
Dani Fenton: Can we ever have an easy battle.
The city burns as a heated battle makes a turn for the worse as explosions happened everywhere, making heavy casualties.
Dan Phantom: I will rip everything you love to pieces!
Dan has Danny by the throat before he gets tackled by Ben, who is as Diamondhead.
Ben Tennyson: We won't let that happen.
Ben, as Humongasaur, had Dan in a bear hug as Stormwolf charged and clotheslined the villain.
Tomahawk: There's gonna be blood spilled.
Tomahawk jumps off a roof and takes two Covenant soldiers out with hidden blades while Kevin sent several flying with his steel mallets. Then Tomahawk gets shot in the ribs by a crystal shot from one of the aliens.
Icewolf: Just like Zeus all over again.
Icewolf and Gwen are back to back sending ice and Mana crashing into Covenent left and right before Red Huntress flies by and blast the aliens down with her ecto-blasters before landing beside her two allies.
Red Huntress: I hate aliens.
NARRATOR: This Summer
Stormwolf and Tomahawk face off against Dan inside a Plumbers' base as Icewolf prepares to attack from the shadows.
Ben Tennyson: I don't think you're being straight with us.
Danny Phantom: It doesn't matter to you.
Phantom and Heatblast collide with attacks of ectoblasts and fire.
NARRATOR: Ten Heroes
Phantom, Spectrum, and Rath are taking on Dan in the park with a broken Gateway Arch in the background, with Dan some how getting the upper hand in the exchange.
Dan Phantom: You don't know what your facing.
Gwen Tennyson: Oh and you do?
Gwen sends a powerful blast of Mana at Dan, followed by a powerful energy blast from Feedback, and ice blast from Icewolf, ectoblasts from Phantom, Spectrum, and Red Huntress, Aang attacking with earth, water, and air, then Stormwolf launches lightning bolts at the evil halfa.
NARRATOR: Become Titans
Dan Phantom: Not even two halfas and an alien shapeshifter can beat me!
The evil halfa looks down at an unconscious Phantom, Spectrum, and Ben 10.
Dan Phantom: Who can stop me now!? Who!?
A howl could be heard in the distance as storm clouds started rolling in. Then suddenly a large black figure landed infront of him, the Stormwolf.
Stormwolf: Hate to interrupt the gloating.
Behind Dan, Avatar Aang lands behind him, staff in hand and preparing to assist Stormwolf.
Avatar Aang: But we'd like to even the odds a bit.
The two heroes then charged towards the evil halfa, ready to do what must be done, while unknown to any of them Tomahawk was trying to aim a gun with a single ecto-bullet in it at the head of Dan.
Titans
Edd Cravens: I feel like Ben and Danny want to kill me.
Whitley Cravens: Well you can probably overpower both of them.
Stormwolf slamming a lightning fist into the ground to break-up the infighting between Danny and Ben.
Kevin Levin: Besides you're dating Phantom's sister.
Proving Kevin's point, Dani walks in and kisses Edd just as Danny walks in the room, not approving of who his sister chooses to date.
