[Ben 10/DC] How effective would Ben be in the DC multiverse?

Pretty much what the title says. How effective would Ben be as a hero in the DC multiverse if the Ben 10 multiverse and the DC multiverse were one and the same?

EDIT: Use the most recent version of Ben for reference, Ben 10K is up for discussion too.

Ben would overly rely on Daxamite, Kryptonian and Martian forms. Most of the aliens in his normal multiverse have a single power that can be called upon, and while that is for the most part true of the DC Multiverse, the existence of Daxamites and Kryptonians and Martians means that he would have access to alien forms with a wide range of powers.

Basically, rather than having to switch between different forms to get the job done, he'd just go Martian and do it solo.
