Old Wrestlers Learning New Tricks?

This question was inspired by the Observer post mentioning Terry Funk adopting moonsaults in 1994. Other than him (the moonsaults and adopting a more hardcore style) and The Undertaker adopting MMA-type moves later in his career, can you think of examples of wrestlers notably changing their style later in their prime or after their prime?

​Sure, there's Shawn Michaels going from daredevil bump machine to master of babyface psychology, Matt Hardy changing from bump machine to evil crime lord or whatever he does now, HHH going from technical wrestler to lost Legion of Doom member in 2002, Scott Steiner going from suplex machine to muscle-bound oaf in 1999…there's lots of examples.​
