Unlike previous incarnations, this version of Leonardo is the rebel and self-proclaimed coolest turtle, instead of Raphael, rather than his normal role as the leader of the team.
Ben Schwartz stated in an interview, that if Leo had an Instagram account, that 60 to 70% of his photos would be his brothers caught sleeping or slipping on things.
Since he isn't the leader, Leo will be more laid-back than his previous incarnations.
Leo also isn't the oldest turtle like in previous incarnations.
Since this version of Leonardo is a red-eared slider turtle, he also sports visual marks (red stripes over his eyes and yellow stripes over his arms and legs) which are common and give this species its name.
He will be creating catchphrases for the group to use.
Leonardo will have the closest relationship with Michelangelo and will be taking him under his wing.
He believes that his one-liners "fire up the team".
According to a behind the scenes video, Leo is confirmed to have the smarts to be a leader, but seemingly lacks the maturity as he is more interested in enjoying life as a teenager.
It is possible that this could foreshadow one of the major changes hinted prior to the series' premiere.
