New Omnitrix Wielder: Ben's Legacy.

Charmed

We see the Omni Squad as they were seen at a field as we see there was a training course as Dimitri looked at Ashton.

Dimitri: Ready to test your new powers?

Ashton: Can I say it?

Dimitri: Go ahead.

Ashton: IT'S HERO TIME!

We see Ashton as he slams the ultimatrix and he transformed into Diamondhead

Dimitri: Diamondhead. One of Ben's best. Ok let's see if you can use him.

We see Tech as he pulled a lever as we see some dummies pop up and Ashton shoots a lot of shards at them tearing the dummies to shreds

Ashton: Now that's cool, no wonder you got to have this much fun!

Dimitri: Yeah, but remember Ash, just don't try to muscle it. Might isn't always right.

Purah: The point is to think through.

Ashton: I know, but it's always fun. Let's keep going, I haven't even broken a sweat!

Franky pulled a rope as cans were fired in the air as Ashton then fired at them as we see Karen press a button as targets came down as Ashton began to fire at them as we see Urbosa, Zelda, Clover, and Zee watching.

Clover: Showoff.

Dimitri: Focus Ash, think with your head not muscles!

Ashton: I know.

We see cans came up as Ashton fired at them but turned to see a tire swing coming as it hits him causing him to fire shards at the group as we see Dimitri take cover while the girls ducked under a table as a sunblock bottle Clover was holding exploded covering her in the contents

Ashton: Oops. My bad.

We later see them going through town.

Clover: You owe me for that.

Ashton: I said I was sorry!

Clover: But still you almost turned us into swiss cheese.

Urbosa: Yes. I may not know what Swiss cheese is but it must not be a good thing to be turned into.

Dimitri: Ash you need to take the Ultimatrix more seriously. It's not a toy, you have to think when you use it.

Tech: Dimitri's right Ashton, you have to be more strategic with it.

Franky: But never thought Purah could come up with a design for the course.

Purah: I had a lot of years doing research.

Lexi: Huh, so how old are you?

Purah: I'm 124.

Tech: You're that old?

Purah: Yeah why?

Usopp: It's just for someone who's basically older than any of us yet looks so young

Purah: I had an aging experiment that helped for that.

Lexi: You mean you found a way to make yourself as young as you want?

Purah: Yeah.

Lexi: Lucky.

Dimitri: But Ash, you do need to understand how to use the Ultimatrix.

Ashton: I've seen you use your watch all the time so I know how to use it.

Dimitri: That's only because I had to understand the responsibility it came with, you need to use aliens other than just bruisers.

Ashton: And what use is Greymatter?
