"They Had To Keep Reinventing This Character Until They Got It Perfect"

Sometimes a character goes through so many reinventions and reimaginings, it feels as though they're just being chewed up by the machine. (See Hawkman.) But sometimes, the 20th version of a character is just... perfect. Which character actually benefited from endless redesigns and reboots?

Please include a picture or clip for your chosen character. And please mention which comics, television series, movies or books he/she comes from. Thanks!

Top image: Blue Beetle. Don't get me wrong. Ted Kord is amazing, and Ted's team-ups with Booster Gold are a thing of wonder. But the greatest Blue Beetle, without a doubt, is Jaime Reyes. The costume, the origin, the character... everything about the version created by Rogers and Giffen is ideal.
