Mephisto and Praxina (more commonly known as The Twins) are the recurring main antagonists in the animated series LoliRock (aside from Gramorr) and its comic book adaptation. They were biological twins from the planet Ephedia who were sent to Earth to steal the Oracle Gems and destroy the Princesses.

Mephisto is voiced by Vincent Tong and Praxina is voiced by Kelly Sheridan.

The Twins


Mephisto was the younger twin brother of Praxina. He had pale skin, emerald green eyes, and burgundy hair. He also wore a white shirt with a green snake symbol and wore umbrella black pants, gloves with green tints and shoes.

He was less coordinated than his sister when he battled the princesses one-to-one without Praxina around, which made him less intelligent. However, he had proven himself capable to be intelligent in the episode Lucky Star, as he had a back-up plan in advance after his sleeping spell didn't reach the princesses and that he used/casted a lot of complex and unique spells in comparison to his sister.


Praxina is the older twin sister of Mephisto. Like her brother, she has pale skin and burgundy hair, but has navy blue eyes. She also wears a black and white skirt with red tints and a symbol of a butterfly.

She is more intelligent than her brother and a very cold-hearted, ruthless and determined person. She is older than Mephisto by several minutes and it is typically her who comes up with the plans against the princesses. Though she is harsh and mean towards others, she truly does care for her brother.



The Twins have a mysterious past, and no one knows their origins or who their parents were. However, in the near-final episode of Season 2, "Forget You!", there are subtle hints that one of the siblings might have been brainwashed into becoming evil, mostly shown at Praxina. This was when their spell that was supposed to target the Princesses, but it backfired at Praxina while Mephisto was hiding from the backfired spell, and then it unleashed a rather strange but suspicious headgear called the Tiara of Runic. This strongly implies that both Mephisto and Praxina were somewhat good people before turning evil, and that Praxina was given the tiara by their parents after their birth, hinting more that their parents were abusive individuals that didn't like how their children were born good-mannered.

Before the Crowning Glory Duology (Seasons 1-2)

Mephisto and Praxina arrived on Earth from Ephedia to bring the Princesses (especially Iris) down by stealing as much Oracle Gems as they can and bring eternal destruction with the help from Gramorr. However, this resulted in multiple fails where the Twins were forced to hear the painful yellings from their master, unknown to the fact that they're already brainwashed thanks to their parents' way of raising them and forcing themselves to become his henchmen. This phase continues until the last part of the final episode of LoliRock; Crowning Glory, Part II.

The Crowning Glory Duology and Mephisto's Fate

During the final battle of the entire series, Mephisto and Praxina (along with Gramorr) fought the Princesses at the dead-end of the controlled Castle of Ephedia, even near the dead end. When Iris sees that her friends Talia, Auriana, Carissa and Lyna are in full danger, she loses control over her powers and transforms into her intimidating and formidable Shanila form. Her battle against Gramorr gets taken to the extreme, and the Shanila-transformed Iris along with her friends cast a spell that instantly killed Gramorr and made Mephisto fall off a cliff along with Praxina and Banes. Praxina survived nonetheless, but Mephisto and Gramorr are nowhere to be seen until Banes arrives with half of Gramorr's mask and gives it to Praxina, making her more powerful.

At the end of the final episode, Praxina (in her current "badass evil" form) gets surrounded with butterflies (her signature symbol) and is prepared for launching a surprise destruction at her loved one (implying that she is going to kill Nathaniel as means of revenge for what Iris did with her brother, though this done by accident since Iris couldn't control her Shanila power-up and therefore has no remembrance of what happened).

Powers and Abilities

Both Mephisto and Praxina had the ability to fly with their capes, teleport and possess black crystal magic. They often used it to attack the princesses, create monsters with it via mutating an animal or other objects and freeze anyone. They also have the power to control minds with certain objects, like Iris's necklace and Talia's shoes. Another power is to shapeshift to look like humans. The princesses has been tricked by that so many times.
