Video Game: NHL 06 (2005)
Zachary Priest was a sick young man who ended up as part of NHL 06 as part of the Make A Wish foundation. So, like, Mark Turmell in the NBA Jam games, Priest is more of a cool easter egg than a dominant creation like some of the other entries on this list, but at the same time, he was a really good player.
He was given a fairly high overall rating along with 85 potential. And since NHL 06 was rushed to be released before NHL 2K6, it lacks the draft picks from that year, including Sidney Crosby, Alexander Ovechkin, and several others, so Priest makes for a nifty replacement to one of the many missing superstars for your franchise mode. Whether or not be becomes dominant is completely up to you.
