¡ATTENTION!: In a fandom says some things about The Teenage Mutant Ninja Turtles 2018 Series, but I'm not saying it's official, (and especially if the editors are obsessed with what is "official and confirmed") though It seems convincing :
Teenage Mutant Ninja Turtles - A team of humanoid mutant red-eared slider turtles who were hidden ever since their mutations within the sewers of New York City and usually go up to the surface only in the night time.
Leonardo/Leo - Leonardo is an enthusiastic perfectionist, wears a blue mask, and fights with twin ninjatō swords. He flirted with several girls throughout the series, '(Leo has flirted? ¿¡FLIRTED!? I thought he was the most responsible and MATURE)' but his main love interest has always been Karai. He also has a similar personality to his 2003 and 2012 counterparts.
Raphael/Raph - Raphael is the hotheaded rebel, wears a red mask, and fights with twin sai daggers. He also has a similar personality to his 2003 and 2012 counterparts.'(When I saw that Raph was going to be the leader, my head exploded, I hope it is more or less like in the 2003 Series, he would be the leader, but he will have one of his rage attacks that everyone loves and Leo will become the leader, because if my Raph does not act like Raph, I'm out)
Donatello/Donnie - Donatello is the brainy pacifist, wears a purple mask, and fights with the single bo staff. He also has a similar personality to his 2003 and 2012 counterparts.
