1. Leon – Reborn!
Leon might look like just a cute little chameleon sitting on Reborn’s hat, but don’t let his appearance fool you. In the anime Reborn!, Leon is no ordinary pet—he’s a memory-type chameleon with the ability to transform into any object the user desires, all while maintaining his original size. Guns, metal detectors, slippers, hammers—you name it.
What’s more, Leon’s tail can act as a danger signal: when it’s cut off, it’s a sign that one of Reborn’s students is in grave danger and his transformation ability becomes unstable…
Leon can also spit out a helmet-like tool that allows someone to change their appearance into anyone else’s. Even more dramatic: after a three-day nap, Leon can produce “Dying Will Bullets.” If shot in the head, someone with no regrets dies instantly—but if they do have regrets, they come back to life with fierce determination. Tsunayoshi Sawada had his fair share of encounters with these bullets early on.
2. Baby-5 – One Piece
With long black hair, a maid outfit, and an attitude that screams “badass,” Baby-5 is both the maid and the assassin of the Donquixote Pirates in One Piece. She’s a Weapon-Weapon Fruit user, which gives her the power to transform any part—or her entire body—into various weapons: guns, swords, cannons, you name it.
Despite her firepower, Baby-5 is incredibly emotionally vulnerable. She craves being “needed” to the point where she can’t say no—even if it means getting scammed, accepting shady proposals, or racking up 98 million Berries in debt. Her neediness led to 50 newspaper subscriptions and countless questionable engagements…
3. Jing Tianming – The Legend of Qin
A kid caught in a world far bigger than himself, Jing Tianming from The Legend of Qin carries a complex backstory. Cursed by the Yin-Yang clan, he’s adopted by a kind elderly couple, only to lose them and end up wandering the streets—until he’s saved by legendary swordsman Ge Nie. Together, they embark on a journey to break the curse.
His weapon, Fei Gong, is the pride of the Mohist School—an engineering marvel that can transform into a sword, bow, shield, grappling hook, and more. It’s essentially a Swiss Army weapon passed down through generations of Mohist Masters.
4. Su Muqiu – The King’s Avatar
Su Muqiu is a genius of the game Glory, mastering every class in the gunner category. He’s the brain behind the custom silver weapons “Evil Annihilator,” “Sun Devourer,” and most notably—the Thousand Chance Umbrella.
This umbrella isn’t just for rainy days—it’s a self-designed, transformable weapon tailored to adapt to all 24 beginner class skills and can morph into nine different forms including sword, rifle, spear, staff, and more. At level 55, it even integrates mechanics to cover a massive range of combat styles. It’s a masterpiece in versatility.
5. Erza Scarlet – Fairy Tail
Known as the “Titania” or Fairy Queen, Erza Scarlet is Fairy Tail’s strongest female mage—and for good reason. Her power lies in Requip magic, which lets her store and instantly equip various armors and weapons from an alternate dimension.
While Requip itself isn’t rare, Erza’s speed and mastery over it are unmatched. She can switch into battle-ready armor tailored to exploit her opponent’s weaknesses in the blink of an eye. Her arsenal boosts her attack, defense, and adaptability, making her a one-woman army.
6. Linie – Frieren: Beyond Journey’s End
Linie might look like a young girl, but don’t let appearances fool you—she’s a powerful demon and one of Aura’s top enforcers in Frieren: Beyond Journey’s End. Her specialty? Mimic magic.
She reads the mana flow of her opponents and replicates their movements and spells with astonishing precision. However, this technique requires line-of-sight and is less effective against physically powerful opponents in close quarters. Ultimately, her strength still hinges on her own abilities.
7. Hal Jordan – Green Lantern
From the world of DC Comics, Hal Jordan is humanity’s first Green Lantern and one of the universe’s greatest heroes. A fearless test pilot with unwavering willpower, Hal was chosen to wield the Green Lantern ring—one of the most powerful weapons in existence.
The ring translates pure willpower and imagination into physical constructs. The stronger the user’s resolve, the more powerful the weapon becomes. From giant fists to force fields to starships—there’s no limit to what Hal Jordan can create, except his own mind.
