(At Prime Earth, Mission City, Tennyson Mansion, Ben, Karen, Ryan, Ace, Zane, Grimlock, Ryo, Daniel, Midnight, Magik, Rogue, Toga, Josh, Mordecai, Rigby, Ryder, PAW Patrol, Kabutack and all Heisei Heroes are together. The Showa Heroes go back to their universe, leaving them to celebrate their victory and the addition of two teammates: Kevin White/Kamen Rider Decade and Gina/Knight Gundam.)

Ben 10: (smiles) We finally made it back home.

Karen: (smiles) All of us are together now.

Gyro: Not yet, this is only the beginning.

Grimlock: He's right, we need all nineteen here.

Ben 10: Yeah, all nineteen teams to fight together.

Gina: Nineteen Leaders and their many allies to fight our enemies once and for all.

(Then they hear footsteps and turn to see the twenty Autobots reuniting together.)

Grimlock: Let me guess, you're leaving as well.

Chromia: (nods) Yes, now that we're reunited together, it's our time to leave.

Sideswipe: (nods) Yeah, it's our time to leave and have our own adventures. But we'll come back sometimes.

Prowl: Yeah, you guys let us reunite at last. We'll never forget that. It's good to see each other again.

Windblade: Yeah, we always have our best match.

(She poses sexily and winks.)

Bulkhead: (smiles) Yeah, we'll have our own... (excited) ADVENTURES!

(Then all Megaforce members hug the Autobots.)

Grimlock: We'll miss you, guys.

Chromia: Yeah, goodbye Grimlock.

(The Aurobots wave their goodbye before transforming into their vehicle modes and leaving Mission City.)

Grimlock: (smiles in tears) Thank you, Autobots.

Red Hood (G. K.): Adios, amigos!

Angelo: Bye, guys. See you later in years.

(The Autobots are seen leaving as their new leader Prowl speaks.)

Prowl: Autobots, roll out!

(They return home as Skidmark follows the Autobots as they leave back to their home state.)

(As the screen fades to black, Grimlock's roar can be heard.)
