Summary
When she was built, a prototype EMH MkX was added to the USS Daradax. It is unclear why a standard version was not put in in 2391 or at a later date but the medical database needed was always up-to-date to match those of the standard EMHs.
When the crew transferred to the USS Sojourner he didn’t want to be left out and transferred himself replacing the EMH on the new vessel. Not wanting to erase a fellow hologram he sent the Sojourner’s EMH to the Daradax.
Appearance
Standing at 1.88m the MkX has a tendency to change its appearance whenever activated but usually appears with a beard and scruffy hair. He will often appear in a Starfleet uniform but will at times appear in causal clothes.
Personality
Overly sarcastic!
