Michelangelo's voice actor was Townsend Coleman in the 1987 series' and Johnny Castro in the 25th anniversary movie "Turtles Forever". Michelangelo also made a couple of appearances in the 2012 series in the episode, The Manhattan Project. He and the other turtles along with Casey and April are seen through a portal by their 2012 counterparts walking on a road and he made a speaking cameo along with the other turtles at the end of the episode when a space worm from the 2012 dimension started terrorizing the street. All four turtles see the worm and spring into action while shouting their famous catchphrase, 'Cowabunga'. Townsend Coleman reprised his role as Michelangelo for the cameo. This would mark the first time in over 28 years the 1987 TMNT cast would return to their roles. With exception of Rob Paulsen who returned to the TMNT franchise as Donatello in the 2012 series. The 1987 turtles also had a crossover with the 2012 turtles in the season 4 episode, "Trans-Dimensional Turtles" then in the three part series final "Wanted: Bebop & Rocksteady".
