Return of The Hero!

Ben is Heatblast and just killed Van Kliess.

Heatblast: That does the job.

Nanitetrix: All nanites used, re-transforming to Ultimatrix.

The Nanitetrix flashed and went back to a Ultimatrix.

Ben: Great!

Rex: What?

Ben: The Nanitetrix is back to the Ultimatrix!

Ken: That is COLD.

Max appeared on a hologram.

Max: Ben. You have to return.

Rex: Ben, Max is right. It's time to leave Bellwood and return to your universe and go to Azmuth. He'll know what to do.

Ken: But where would I go? I can't go back to the future since 20 years later as it's super locked.

Ben: (sighs) Stay with Rex. Fate brought you to him so Fate would want you to stay in Providence.

A portal opens and a Celestialsapien hand grabs Ben in.

Ben: AAAHHHH!!!!!!!!!! (Slams Ultimatrix)

Rex, Ken, Six and Doctor Holiday: BEN!

Theme Song!

It shows Ben floating in the Forge of Creation.

Ben, echoing: Where (Where) am I? (am I?)

???: The Forge of Creation, Ben. We've been expecting you.

Ben: And you are?

???: I am Ambu. Short for Ambush. I like to fight. I am the first ever Celestialsapien.

Ben: Oh. What universe is this?

Ambu: The Infinite Universe. The Universe where to everything will keep going on. And you are the Hero Of Infinity!

Ben: For the fifth time? I have to do what I do best? I wish there was a universe when somebody tricked everyone of me being gone. Or if Gwen had the Omnitrixes. But NO! I have to be the hero around here!

Celestialsapiens: Um......

Ambu: Goodbye.

Ben: AHHHHH!!!!!!!!!!!!

He teleports to Infinite Bellwood.

To be written....
