The Guardians of Eternal Youth are a mystical group of five large, chubby babies who possess the power to grant and protect eternal youth. Known for their deep, mature voices despite their infantile appearance, they are revered by Skips, who worships them to maintain his immortality. These enigmatic beings play a crucial role in the magical universe, acting as both protectors and powerful agents of eternal life.

== Appearance == The Guardians resemble oversized infants, characterized by their round faces and chubby bodies. Each wears a gold hat, a brown bib, and what looks like a white diaper—though the "diapers" are later revealed to be something else entirely. Their deep voices contrast starkly with their baby-like looks.

As members of the Magical Elements in the episode "Skips Strikes", they adopt a slightly different look. Reginald, the leader, notably wears a black button-up shirt with the team’s name elegantly scripted on the chest. During a Halloween party featured in Terror Tales of the Park III, half of the Guardians dressed in baby blue superhero costumes, complete with yellow masks and matching belt buckles.

They have also teamed up with the god of basketball, Death, and a wizard to form a new incarnation of the Magical Elements during a dodgeball tournament. In this event, the Guardians sport black V-neck shirts and shorts trimmed in white, paired with black shoes and white socks. Flashbacks to their high school days, shown in "Skips' Story", depict them wearing brown suits with black ties and white poet shirts underneath.

== Personality == Though the Guardians of Eternal Youth appear as innocent, oversized babies, their personalities are anything but childlike. Across their various appearances, they reveal themselves as cunning, confident, and sometimes downright mischievous cosmic beings with a flair for drama and domination.

Reginald is the outspoken and authoritative leader of the Guardians. His commanding presence contrasts sharply with his infantile form, and he often exhibits impatience, especially with Skips and Quips. He has a strong sense of pride in his powers and takes his responsibilities seriously, though he is not above using his magic to play mind games or punish those who annoy him. His repeated displays of telekinesis, energy projection, and illusion creation highlight his versatility and tactical mind.

Archibald, the once-mighty Guardian who was killed in battle, showed a fierce, battle-hardened side that hinted at a more aggressive personality beneath the chubby exterior. His death at the hands of Klorgbane marked a turning point for the group, casting a shadow of vulnerability over the otherwise immortal Guardians. Archibald was known for his loyalty and strength, traits that inspired the surviving Guardians.

Oswald, Boswald, and Griswald, while less individually spotlighted than Reginald or Archibald, often act in unison, displaying a mix of mischief and solemnity. They share the group’s love for cake and schemes to expand their cosmic influence. These three add a layer of playful unpredictability, sometimes supporting Reginald’s plans, other times acting independently with subtle cunning.

== Abilities == The Guardians possess a vast array of magical and supernatural powers, often utilizing their signature Magic Rattles to channel their magic.

• Magic Rattles: Each Guardian wields a magical rattle that enables them to cast spells, including the power to strip Skips of his eternal youth.
• Flight: They can effortlessly float and move through the air.
• Immortality: They are ageless beings who can grant eternal youth to others. However, they are vulnerable to physical harm and can be killed, as evidenced by Archibald’s death at the hands of Klorgbane.
• Omniscience: The Guardians possess infinite knowledge and can absorb information from anyone.
• Teleportation: They can instantly teleport themselves and others, such as when Mordecai, Rigby, and Skips were teleported back to Skips’ house.
• Telekinesis: Reginald demonstrated telekinetic abilities by controlling a bowling ball during Skips Strikes.
• Ice Manipulation: Reginald can create ice to hinder opponents, demonstrated by causing Mordecai to slip.
• Energy Projection: They can shoot powerful energy beams from their eyes and Magic Rattles.
• Meteor Summoning: Reginald summoned meteors in an attempt to sabotage Skips during a bowling match.
• Summoning: They can call upon the Fists of Justice at will.
• Sealing: Reginald once sealed Quips and Skips inside a cube to silence Quips’ jokes.
• Electricity Manipulation: Used by Reginald to zap Mordecai and Rigby during their rescue attempt.
• Illusion Creation: Reginald created distorted illusions of Quips to annoy him.
