crossword: nobody can stop him

[Boris Tatarenko]

Hello.

I'm doing a crossword puzzle and I've come across a difficult question. I gave up.
Would you like to help me?

The question is: No one can stop him when he wants someting. He's really _ _ _ e _ _ _ _ _ _.

The second question is: does "unstoppable" work here? (I know "unstoppadle" can't match into the gap, but I'm not sure whether it works)

Thanks.

Yes, you could call him 'unstoppable.'

The word you want begins with d.
