Rottmnt (2018)

Physical Characteristics: Species: Spiny turtle.
Shell: Unlike other incarnations, its true shell is soft, flat, and leathery. Therefore, it uses an artificial purple "battle shell" attached to its back for protection.
Appearance: He has jade-green skin with purple geometric markings on his arms and thighs. He has a slender build, a large head (indicating his intelligence), and three fingers on each hand and foot.
Accessories: Wears a purple mask that covers his entire head, asymmetrical glasses (one red lens and one blue lens) on top of his head, and a technological gauntlet on his wrist.
Species: Its official species is a mutant spiny turtle (Apalone spinifera). In real biology, these animals are known for having flexible shells instead of a rigid, heavy carapace. This species choice was made by the creators to create a visual contrast and justify why this version's Donatello would need to build an artificial shell.

Michelangelo (often called Mikey) from the animated series Rise of the Teenage Mutant Ninja Turtles (released in 2018) is the youngest of the group. He is known for his extremely vibrant, optimistic, and artistic personality, and for being the emotional and mystical heart of the team.

In the Rise of the Teenage Mutant Ninja Turtles series (2018), Raphael is the eldest brother and leader of the group.

In the Rise of the Teenage Mutant Ninja Turtles series (released in 2018), Donatello is the most ingenious, sarcastic, and tech-focused turtle. Unlike other versions, he is a genius with low emotional intelligence, very proud of his inventions, and prefers to rely on his high-tech gadgets rather than hand-to-hand combat.

Main Features:

Species: It is a Spiny Softshell turtle, which makes it naturally more fragile in the carapace compared to its siblings.
Weaponry: He uses a bō staff with mystical technology that transforms into various other weapons and tools during fights.
Personality: He is a "mad scientist" and dramatic, often ironic, cynical, and impatient with his siblings' predictable habits.
Emotional Intelligence: He may demonstrate low social empathy and tends to value hard logic and bluntness.
Relationship with his brothers: He acts as the "brains" of the team, but doesn't hesitate to try and solve problems independently. He has a very close relationship with Mikey, whom he considers his intellectual and creative equal.

In the 2018 version (Rise of the Teenage Mutant Ninja Turtles), Leonardo is portrayed as the second oldest brother and acts as the rebellious, witty, and charismatic member of the group. Unlike the classic versions where he is the serious and stoic leader, here he is a sarcastic prankster.

Personality and Behavior:

Charismatic and playful: He is known for his humor, sarcasm, and for loving the spotlight. He uses jokes and witty remarks to deal with tense situations, sometimes doing so at inappropriate times.
Good looks vs. leadership: Initially, he wants to be seen as the "cool guy" or the coolest member of the team, but he prefers that his older brother, Raphael (Raph), handle the responsibility of being the leader.
Leader Evolution: Over time, he matures, overcoming some insecurities and embracing his true potential as a strategist and future leader of the team.

Combat Style and Skills:

Quick strategist: Beneath his carefree demeanor, he is an incredibly agile fighter and a quick tactical thinker, capable of analyzing situations and creating escape routes or plans in the heat of the moment.
Mystical weapon: He wields a mystical ōdachi, a magical sword that creates teleportation portals, allowing him to maneuver around enemies and attack from unexpected angles.

Dynamics with Siblings:

The "Middle Brother": Because he doesn't carry the initial burden of leadership, he has more time to focus on his own self-affirmation and having fun with his brothers.
Disaster Twins: He and Donatello (Donnie) have a very close dynamic of constant teasing and complementary teamwork.

In the 2018 animated series, Rise of the Teenage Mutant Ninja Turtles, Leonardo is a red-eared slider turtle. He adopts a more rebellious, charismatic, and playful demeanor, rather than focusing solely on being the disciplined and stoic leader.
