Let's say the phrase I want to write is "all of the Mike Tysons, Donald Trumps, and Morpheus's in the world." I'm guessing that the first two names do not need one and the third does. Is this correct?

One never forms plurals out of English words via an apostrophe. The apostrophe indicates a possessive, not a plural.

The English plural of Morpheus is simply the regular plural Morpheuses.

    Well, hardly ever. When I was young the standard way (as in stylesheet and school standard) of pluralizing letters, numbers, initializations and a handful of things like do's was with 's. That's now mostly deprecated (and I'm glad to see it go, though Dos and Don'ts still looks odd to me), but it still lingers here and there. Commented Aug 26, 2015 at 1:12

What you are using is one form of posessive, like "Mike's shoes", or "Morpheus' eyeballs".

Instead you need a plural. Some words don't have a plural.
Some have an awkward plural, that comes from the originating language, like "Ox -> Oxen".

The plural of Morpheus is Morpheuses, I'd say. And yes, it's an awkward plural.
