Final Goodbye

## Plot

The episode starts off with the camera angled at Zombozo, who is tied up after attempting to steal a brain from the brain bank, as the camera moves away from Zombozo, Ben, Gwen and Kevin enter the scene. Ben tries to persuade Gwen and Kevin to stay, but Gwen states that the colleges in Bellwood aren't quite the same as the Ivy League. Gwen explains that they've spent years saving the world, and she finds it a good time to see what she's been saving. Kevin explains to Ben that he isn't coming back after finding a place near campus.

After sharing their last moment, Gwen and Kevin take off to the Ivy League college. Zombozo mocks Ben about no longer having team members to help him save the day. Ben takes this as an opportunity to become a solo superhero, but explains that he needs food after battling with an empty stomach.

The scene skips to Ben driving in his car, the DX Mark 10, towards Mr. Smoothy, but states that it "wouldn't be the same". He drives off and stops by in Julie's house. Julie asks about Gwen and Kevin's disappearance, to which Ben explains that Gwen had to go to college. Julie explains that she's got a game in half an hour and asks if Ben would like to watch the game, but Ben refuses the request.

After getting a phone call from Grandpa Max, Ben heads out of Julie's house and drives off to Plumber HQ. Ben arrives at Plumber HQ and heads over to Max, facing a screen from a destroyed building. Ben uses this as a chance to go solo, but Max claims that Ben needs a team. Ben refuses the offer and goes alone. After arriving at the building which has completely collapsed in on itself, Ben investigates the area but is ambused by a pack of DNAliens.

The DNAliens charge at Ben who dials his new Omnitrix, hoping for Humungousaur, but transforms into Cannonbolt instead. Cannonbolt uses this time to adapt a new fighting style, but is shot down by DNAliens' slime. Locked in place, Cannonbolt watches as the DNAliens begin placing a newly installed Weather Tower. There, the Highbreed enter the scene.

Cannonbolt thought that the Highbreed didn't want to invade Earth after he revived their genetic DNA, but the Highbreed explain that they're invading Earth to take the core, as their planets' core had melt down. Cannonbolt transforms back into Ben and runs over to the Highbreed, demanding them to stop, to no avail. The Highbreed began to demand execution of Ben Tennyson at all costs. Ben uses this time to escape by transforming into Heatblast, annoying the Highbreed, who then demand to get their hands on the Earth's core, which will then result to the collapse of the Earth.

The scene enters Gwen and Kevin arriving at the Ivy League college. Gwen gets out of the car and thanks Kevin to taking her there. She kisses him on the cheek before entering the courtyard. Kevin drives off to his garage to work, knowing that Ben would have to face doing the hero business by himself.
