Isn't it right to say "he is mighty"? Why is the order like that?

Yes, normally the correct structure here would be "he is mighty". "Mighty is he" is an example of inversion, where the verb and adjective in the sentence come before the subject. Inversion is less common in English nowadays, but it was more common to use in the past. Inversion of verbs and adjectives was originally used for emphasis of that verb.
