Mikey’s hero identity The Turtle Titan
Michelangelo is the youngest of the Teenage Mutant Ninja Turtles and is a party dude and he is also easily distracted and even that he screams like a little girl.
When Mikey was a baby, he and his brothers were mutated by a mutagen that fell out of the back of a truck during an accident. He was raised alongside his brothers by Master Splinter who taught them in the art of ninjutsu.
When he was a little older, he and his brothers went with Master Splinter to Japan to bury Master Yoshi's ashes next to his beloved. While there, they helped Master Splinter and the Ancient One win a fight against a demon and that was when they gained their ninja masks.
At some point as a kid, he tried to break Leo's katanas, but when he failed, he tried to hit him with his nunchucks, but Leo retaliated and knocked him down.
Michelangelo became one of the Ninja Tribunal's Acolytes along with his brothers. It should be noted that although Michelangelo tends to goof off, his spiritual avatar is that of a dragon along with his brothers as seen in the episode New World Order, Part 2. It was seen that he was advanced when it came to the stealth training with Hisomi-shisho.
In this series, Michelangelo, along with his brothers, traveled into the year 2105 and met the great-grandson of April and Casey, Cody Jones. Mikey continued his video gaming in the future, completely awestruck by the new video games, especially since most of the games were virtual reality pieces. When the Turtles and Master Splinter reached the future, they were provided with tech-upgraded weapons, courtesy of O'Neil Tech. Michelangelo first chose a giant power armor suit, which kept Mikey happy for five seconds before he found out that it was too cumbersome for him to operate; so he returned to his (though upgraded) nunchaku standards.
Overall, Michelangelo continued being the obnoxiously annoying little brother. He kept his addiction for video games and it even increased and he became even more obsessed with them, which proved to be a hazard during Graduation Day: Class of 2105 which almost got him to not graduate as he missed a month's worth of training just for playing video games. He made up for it, however, when he passed the three tests to graduate and got back his nunchucks: Invisibility, Strength, and Insight. He also passed the hidden test of humility after admitting that he did not deserve to graduate just because he passed three tests after missing so much training.
In this series, Mikey continues to be obnoxious and pestering as he always has been in the 2003 series. Mikey was sad to leave behind all of his stuff in the future, including his video games and weapons. Michelangelo still loves his video gaming, and this becomes an important factor in the episode "SuperQuest", where the Turtles must enter one of Mikey's video games to collect more of Master Splinter's data bits that were lost in the beginning of the series.
In "City Under Siege", Mikey defeats the Cyber Shredder by destroying the platform they were on and burning Shredder to a crisp.
Mikey also goes to Casey and April's wedding at the end of the series where he battles Foot ninjas and helps beat the Cyber Shredder. Afterwards he sees Casey and April getting married. By this point he seems to have matured a little bit.
In Turtles Forever, Mikey gets along just perfectly with the 1987 turtles and often remarks "I love these guys!" - in complete contrast to Raphael, who calls them clowns, and greatly prefers the turtles from the Mirage Comics.
However, when the 1987 turtles go too far with playing around, even Mikey gets annoyed with them, proof that even he can be serious, sometimes. The 1987 turtles also give him noogies. Michelangelo is fond of the 1987 turtles belt buckles, immediately because it reminded him of superheroes. When Ch'rell showed them other worlds, Mikey along with the 1987 turtles was amazed by the multiverse showing even more turtles.
He was in the final battle with the Shredder in Turtle Prime and was happy to see Ch'rell destroyed for good.
