5. Robert Picardo; Emergency Medical Hologram, VOY
When the Emergency Medical Hologram (EMH) first appeared on Voyager, audience wondered what took so long? It seemed improbable that such an advanced civilization didn’t have an artificially intelligent doctor hundreds of years before that. The EMH was so serious he was funny and was well loved by Trekkies. In fact, they liked him so much Picardo reprised his role in a very funny moment during one of the Next Generation movies. Robert Picardo was successful before Star Trek, so he landed on his feet after Star Trek. He’s been a very busy boy since 2001.
