Melvin

Ace is cool, calm, and collected most of the time. He meditates to maintain any temper that may arise. He is a bit of a trickster and likes to poke fun at both friends and enemies alike, much like his ancestor Bugs.

Ace Bunny is a main character of Loonatics Unleashed. He is the leader of the Loonatics. He is adroit, quick-witted, and loyal to his friends and teammates.

Ace's weapon of choice is the Guardian Strike Sword, a collapsible sword revealed in the second season to be a Frelengian energy weapon. Other than the powers granted by the meteor strike, he is also an adept martial artist.

Duck is usually shown up by other characters or angering them with his antics. He is very boastful and has a habit of attempting to re-invent himself (such as requesting name changes for himself, or attempting to add a cape to his uniform). He can also be extremely opportunistic, once trying to be Slam Tasmanian's wrestling manager simply for profit, then haggling with Slam over how much each of them should get (with the preference that Duck receive 90% and Slam 10%). Of all the characters, he seems to be used most often as comic relief, despite or perhaps due to his arrogant personality. This appears to be mostly bluster, as in truly dire circumstances he sometimes lets a more heroic personality show through.
Danger Duck (usually referred to as just Duck) is the deuteragonist of Loonatics Unleashed. He is the spotlight hungry, egotistical member and co-leader of the Loonatics. He wears a black and orange uniform, a pair of blue eyes, and a small mohawk.

Lexi is a tomboy with a love for fashion and trends. Like her allies in the Loonatics, she is a selfless and brave hero ready to risk her life for the greater good. She is best friends to her leader, Ace.

Lexi Bunny is the tritagonist of Loonatics Unleashed and the only female member and Co-Leader of the Loonatics. She is an anthropomorphic rabbit.

Before gaining her powers, Lexi was a student at Acmetropolis University who tried to join the school's cheerleading squad. The captain, afraid she was too good, did not accept her. Lexi enjoys playing video games in her spare time and is implied to be the best of the team at it, and wears a pink uniform. She leads the group alongside Ace Bunny and Danger Duck (on occasion).

He loves games, especially checkers.

Melvin the Martian is a futuristic descendant of the classic Warner Bros. character Marvin the Martian, reimagined with a sharper, anime-inspired design for the animated series "Loonatics Unleashed" . He appears in Season 2 as a villain who travels to Acmetropolis to shrink it, serving as the main antagonist of the episode "The Man in the Mirror" .

👾 Appearance & Personality

· Visual Design: He sports a modified Roman-style helmet with a green and yellow visor, a blacked-out face, and large, expressive purple eyes. His outfit includes an orange tunic, white gloves, and a green skirt-like apron .
· Anime Influence: His look feels more intense than Marvin’s, thanks to his expressive eyes and the metallic gauntlets that make him seem more agile and action-ready .
· Character Role: He’s not just a simple troublemaker—he’s shown as a mischievous strategist. He tries to negotiate with the Loonatics and even challenges Lexi Bunny to a game of Celestial Checkers, all while plotting to use a Uranium PU-36 Explosive Space Modulator to destroy Acmetropolis .

Melvin comes to blow up Acmetropolis after his spacecraft was hit by a missile that came from Tech's X3000 Automated Weapons System when Rev and Lexi mistake it for a video game. He demanded the planet surrenders or he'll destroy it. After a talk with Duck, Melvin decides to shrink it. When Lexi admitted tampering with Tech's invention, Melvin ordered the Loonatics to hand her over to him in 24 hours or "the planet will be hard to find on any map."

Lexi ended up surrendering to Melvin and the Loonatics get her back using an idea from Rev- to create a Trojan horse. While Lexi faces off against Melvin in a game of Celestial Checkers (while Melvin is secretly having his warships shrink the rest of Acmetropolis), he also attempted to blow up Ace with a Uranium PU-36 Explosive Space Modulator (Marvin used an Aluminum PU-36 Explosive Space Modulator) but got his helmet blown off instead after arguing with him over who'd get it. Ace, Duck, Rev, and Slam rescue Lexi, restore Acmetropolis, and defeat Melvin who escapes with his dog Sergeant Sirius.
