Generation VII · #0747 — Brutal Star Pokémon

Mareanie, known as the Brutal Star Pokémon, is a dual-type Poison/Water Pokémon introduced in Generation VII. With National Pokédex number 747, Mareanie represents a fascinating entry into the water-type ecosystem, combining aquatic adaptability with potent toxic capabilities. Standing at only 0.4 meters tall and weighing a mere 8.0 kilograms, this unassuming creature belies a predatory nature that makes it a formidable hunter in its native oceanic environment. As the base form of the evolution line that culminates in Toxapex, Mareanie occupies a crucial ecological niche, serving as both predator and prey within the complex underwater food chains of the Alola region and beyond.

Mareanie Biology & Physical Characteristics

Mareanie possesses a distinctive morphology reflecting its echinoderm-like classification, featuring a purple, stalk-like body divided into two overlapping sections with blue eyes adorned with yellow pupils and sclera. The creature's most striking feature is the starfish-shaped crown of ten light blue tentacles emerging from its head, each covered in purple spines and reaching toward the ground, except for the shorter frontal appendage that leaves its face exposed. Crowning this peculiar arrangement is a purple area studded with spikes, among which sits a prominent yellow spine serving as Mareanie's primary weapon. According to Alolan Pokédex entries, Mareanie possesses remarkable regenerative abilities, capable of regrowing any body part except its head overnight—a trait its hidden ability Regenerator mirrors in gameplay mechanics by restoring one-third of maximum HP when switched out. Interestingly, severed limbs from Mareanie possess an intensely bitter and astringent flavor, rendering them unsuitable as sustenance despite their visible appeal.

Mareanie Breeding, Gender Ratio & Egg Groups

Mareanie maintains a perfectly balanced gender ratio of 50% male and 50% female, following standard Pokémon breeding conventions without any species-specific sexual dimorphism or unusual mating behaviors. The species belongs to the Water 1 egg group, indicating compatibility with other water-dwelling Pokémon for breeding purposes and suggesting shared ancestral characteristics with various aquatic Pokémon lines. Breeding Mareanie results in offspring that hatch after approximately 20 egg cycles, equivalent to roughly 4,884 to 5,140 steps, placing it within the standard hatching timeframe for Generation VII Pokémon. The base friendship value of 70 indicates that Mareanie, while not immediately trusting of trainers, demonstrates moderate willingness to bond through proper care and training. This moderate starting friendship distinguishes Mareanie from both more naturally affectionate species and more aloof legendary or pseudo-legendary Pokémon, positioning it as a balanced prospect for competitive breeding programs.

Mareanie Evolution, Mega Evolution & Special Forms

Mareanie undergoes its singular evolution into Toxapex upon reaching level 38, a transformation that fundamentally restructures its combat capabilities and biological form. This evolution represents not merely a growth increase but a metamorphosis into a more robust predator, with Toxapex developing substantially improved defensive capabilities and a more specialized hunting arsenal. The evolutionary line contains no Mega Evolution or regional variant forms, maintaining consistency across all game generations since Mareanie's introduction in Generation VII. The relationship between Mareanie and Toxapex exemplifies a straightforward evolutionary progression, where the base form's foundational characteristics—particularly its poison-based attacks and water-type moves—become refined and more potent in its evolved counterpart.

Mareanie Behaviour and Natural Habitat

Mareanie inhabits the sandy beaches and ocean floors throughout multiple regions, though it demonstrates particularly established populations in the Alola archipelago. These creatures exhibit gregarious behavior, typically living in coordinated groups rather than as solitary hunters. Their predatory strategy revolves around a precise two-stage hunting methodology: the creature initially subdues prey by plunging the poison spike atop its head into unsuspecting targets, then delivers finishing blows through coordinated strikes from its ten tentacles once prey weakens sufficiently. The Pokédex reveals that Mareanie's poison induces numbness as an initial symptom, followed by an intensely itching sensation so overwhelming that victims are compelled to claw at their own skin uncontrollably. In terms of diet, Mareanie demonstrates regional variation in prey preference—Alolan populations actively hunt Corsola branches as their preferred delicacy, considering this coral a "five-star banquet," while Galarian Mareanie populations have yet to develop this particular hunting behavior. Remarkably, these creatures also consume broken-off Pincurchin spines despite the considerable risk of electrical shock.

Pokedex Entries

Generation VII

sun

It plunges the poison spike on its head into its prey. When the prey has weakened, Mareanie deals the finishing blow with its 10 tentacles.

ultra sun

They eat Corsola branches, so Mareanie are hated by craftsmen who work with Corsola branches that have naturally fallen off.

moon

It’s found crawling on beaches and seafloors. The coral that grows on Corsola’s head is as good as a five-star banquet to this Pokémon.

ultra moon

Aside from its head, its body parts regenerate quickly if they’re cut off. After a good night’s sleep, Mareanie is back to normal.

Generation VIII

sword

The first symptom of its sting is numbness. The next is an itching sensation so intense that it’s impossible to resist the urge to claw at your skin.

shield

Unlike their Alolan counterparts, the Mareanie of the Galar region have not yet figured out that the branches of Corsola are delicious.

Mareanie Name Origin & Design Inspiration

Mareanie's name derives from a fusion of "mare" referring to its aquatic nature and "anemone," reflecting its tentacled anatomical structure that closely resembles sea anemones found in actual marine ecosystems. The Japanese designation "Hidoide" combines elements suggesting "hideous" with phonetic nods to sea creature terminology, emphasizing the species' somewhat grotesque appearance that masks its efficiency as a predator. The creature's design philosophy clearly draws inspiration from real-world echinoderms, particularly starfish and crown-of-thorns starfish, organisms known for their regenerative capabilities and venomous properties. This naturalistic grounding provides Mareanie with biological plausibility despite its fantastical nature, presenting what essentially amounts to a venomous, regenerative sea creature given Pokémon-specific traits. The Brutal Star epithet perfectly encapsulates both the starfish-like visual design and the creature's aggressive hunting methodology, emphasizing the contradiction between its diminutive appearance and disproportionate ferocity.

Mareanie Competitive Battle Guide

From a competitive battling perspective, Mareanie occupies a lower tier of viability due to its base stat total of only 305, distributed across relatively unimpressive individual statistics with only its defense stat of 62 representing a minor strength. Its base attack of 53 and special attack of 43 severely limit offensive potential, while speed of 45 ensures it generally acts last in turn order unless supported by speed-boosting items or abilities. However, Mareanie's dual Poison/Water typing grants access to an unusual combination of type advantages and resistances, and its three available abilities offer distinct strategic pathways. Merciless provides critical hit guarantees against poisoned targets, enabling a specialized status-stall strategy in formats permitting such approaches, while Limber prevents paralysis, offering utility in teams struggling against electric-type opponents. The hidden ability Regenerator represents the most competitively viable option, providing passive HP recovery upon switches and enabling defensive pivoting strategies that leverage Mareanie's defensive typing to wall specific threats. Most competitive implementations reserve Mareanie for casual or fun team compositions rather than serious ladder climbing, though its evolution Toxapex achieves substantially greater competitive relevance with superior overall statistics.

Mareanie Cultural Impact & Franchise History

Mareanie achieved notable cultural prominence through its adoption by Team Rocket member James in the Pokémon anime series, where his particular Mareanie became a recurring character with distinctive personality traits and emotional development arcs. This major anime appearance significantly elevated Mareanie's recognition among the fanbase, providing extensive screen time and narrative focus that would otherwise be unavailable for a relatively early-generation water-type species. The creature's unusual visual design—combining elements of both cute and grotesque aesthetics—resonated particularly strongly with players seeking Pokémon that subvert traditional design expectations. Furthermore, Mareanie's predation relationship with Corsola generated additional cultural relevance through discourse regarding environmental conservation themes, as its dietary habits contributed to evolving conversations about how Pokémon games handle ecological relationships and species survival dynamics. The creature's status as one of the few Pokémon capable of the Merciless ability created specialized competitive interest among dedicated players seeking to exploit this uncommon ability interaction, while its unique typing combination ensured continued discussion among theorycrafters exploring optimal team compositions.

Where to Find Mareanie in Every Pokémon Game

Mareanie first became available to players during Generation VII's release with Pokémon Sun and Moon, inhabiting the waters surrounding the Alola region where it could be encountered on beaches and seafloors throughout multiple islands. The species maintained consistent availability throughout subsequent Alola-focused games including Ultra Sun and Ultra Moon, though it did not appear in the later Generation VIII releases for Nintendo Switch until Pokémon Sword and Shield introduced it to the Galar region with Pokédex entries documenting the regional variant population's distinct behavioral traits regarding Corsola predation. Generation IX's Pokémon Scarlet and Violet expanded availability to Paldean waters, confirming the species' establishment in multiple distinct world regions. Beyond mainstream titles, Mareanie has appeared in various side games and events throughout the franchise, though it remains more commonly available in water-type focused areas rather than being restricted to special distributions or limited-time availability windows. For players seeking Mareanie in contemporary games, water-type habitats in Scarlet and Violet provide the most straightforward encounter rates, while historical players can access the species through Pokémon Home transfers from earlier generation titles, ensuring consistent availability across the modern Pokémon gaming ecosystem.
