(Two weeks after the battle in Mission CIty, the buildings are seen bring rebuilt. The Alien Dino Thunder Megaforce build up more teams. Ben and Karen go out for dinner along with his brother and his friends. Mordecai and Rigby are working in the courtyard while Rick Taylor is seen playing with his son David. Juzo and Kenzo return to Japan along with Jun and Koji. Isaac and his team return to their base as well. Grimlock is seen in the top of the New Tennyson Mansion smiling, but then a female voice is heard.)

????: Grimlock!

(Grimlock turns to see Gwen.)

Gwen: (smiles) I was wondering where you were.

Grimlock: (smiles) I'm out here thinking about that Victorian Dragon Kaiju named Virgo. I don't understand why his world is the same as ours.

Gwen: Me neither. Aliens don't co-exist with Earth's monsters.

Grimlock: But as long as we can protect the earth from any harm, every help is welcome.

Gwen: (giggles) Yeah. And I think Ben is really happy with Karen.

Grimlock: Same.

(Then they look at the sight of Mission City.)

Gwen: (smiles) It looks nice up here.

Grimlock: (smiles) It does, it sure does.

(Then they see Rick throwing a football for David to catch it.)

David: Interception. Touchdown!

Rick: You did it, David.

Rick/David: (high five) Yeah!

(As the screen fades out, the logos of Alien Dino Thunder Megaforce and Neo Super Robot Delta Patrol are shown.)
