Loki, a name belonging to a character in the recent films "Thor" and "The Avengers," came in a very close second to Dexter, rising to No. 28 in 2012 after breaking into the top 100 in 2006.
Izzy also made its way onto the top 100 list in 2006 after "Grey’s Anatomy" (with a character named Izzy) debuted, and it climbed to No. 39 in 2012. The character may no longer be on the show, but the name certainly stuck.
