15 Heaviest Anime Characters, Ranked

Size in anime is all over the map, from dense cocoons to city-sized legends. This lineup focuses on characters with official or publisher-listed weights that appear on screen in anime, so every entry is grounded in numbers rather than guesses. When a character has different forms the entry uses the specific form with a stated mass.

To add variety, the list includes a few giants from outside the usual creature catalogs along with well-documented heavy hitters that recur across long-running series. Each entry notes the weight and key appearances in episodes or films so you can connect the figure with what you see on screen.

Metagross

Metagross weighs 550.0 kilograms and stands about 1.6 meters tall. The species is formed from the fusion of four Beldum and is categorized as Steel and Psychic type, which aligns with its compact frame and dense armor. Its combat moves in the anime include Meteor Mash and Hyper Beam and it often lands from short hops with enough force to mark the field.

Prominent appearances include Steven Stone’s Metagross in ‘Pokémon’ episodes and specials as well as tournament arcs where it anchors teams with high physical durability. Scenes commonly show it planting its legs and resisting knockback, which fits a mass of more than half a metric ton.

Copperajah

Copperajah weighs 650.0 kilograms and is roughly 3.0 meters tall. It is a Steel type with a copper green hide and a reinforced trunk that is depicted moving heavy loads in industrial settings. The large feet and wide stance match its role as a work oriented Pokémon in its home region.

In ‘Pokémon Journeys’ and related Galar stories, Copperajah appears around energy facilities and excavation sites and is directed to push containers and clear debris. Team Rocket encounters and training sequences show it performing tasks that take advantage of its listed mass.

Giratina

Giratina in Altered Forme weighs 650.0 kilograms and stands about 4.5 meters tall. It is a Ghost and Dragon type linked to the Reverse World and it transitions to Origin Forme under specific conditions, which changes its body plan but not the core lore that defines it as a heavyweight entity.

Key anime material includes its feature role in ‘Giratina and the Sky Warrior’ and follow up appearances connected to ‘Arceus and the Jewel of Life’ and series episodes. Interactions with terrain and collisions with other Legendaries are framed to convey the mass attributed to this form.

Dialga

Dialga weighs 683.0 kilograms with a height of 5.4 meters. It is a Dragon and Steel type that governs time within franchise lore and carries segmented armor and crystalline protrusions that concentrate energy for signature techniques like Roar of Time.

Dialga’s conflict with Palkia in ‘The Rise of Darkrai’ and its later returns in ‘Pokémon Journeys’ provide multiple episodes where the ground response and structure strain are visible during movement. The way platforms and streets react when it steps or lands is consistent with a mass that approaches seven hundred kilograms.

Melmetal

Melmetal weighs 800.0 kilograms and stands about 2.5 meters tall. It is the evolved form of Meltan and consists of mutable metal that centralizes around a hex nut core, which is why its limbs move with piston like regularity during close range attacks.

Ash’s Melmetal competes in the Alola League in ‘Pokémon the Series: Sun & Moon’ and appears in training and tournament episodes that emphasize strikes like Double Iron Bash. The arena flooring dents and the ring posts flex during contact, which illustrates how an eight hundred kilogram frame behaves in competition.

Stakataka

Stakataka weighs 820.0 kilograms and reaches about 5.5 meters when assembled. It is an Ultra Beast made of multiple stone like units that lock together into a single body, and the individual modules can separate and reassemble if necessary.

In ‘Pokémon the Series: Sun & Moon’, Stakataka is first mistaken for part of a stadium wall and is later guided away from crowds when it starts to move. The story shows the ground scuffing and tiling cracking under its base as it shifts its full weight.

Guzzlord

Guzzlord weighs 888.0 kilograms and stands around 5.5 meters tall. It is an Ultra Beast with a massive torso and jaws that open wide enough to engulf vehicles, which ties its appetite and destructive capacity to an official mass near nine hundred kilograms.

Ultra Guardian missions in ‘Pokémon the Series: Sun & Moon’ feature Guzzlord as an ongoing hazard that devours machinery and sections of terrain. The teams bring in heavy gear and containment measures that have to account for the weight and size listed for this creature.

Mudsdale

Mudsdale weighs 920.0 kilograms and stands about 2.5 meters tall. It is a Ground type equine that hardens the mud on its legs into protective coverings, which allows it to deliver high impact kicks while carrying a load near a metric ton.

Hapu’s Mudsdale appears throughout Alola stories in ‘Pokémon the Series: Sun & Moon’ where it serves as a transport and a partner in trials. Footage shows deep hoofprints and compressed soil along paths after runs, which provides a clear picture of how a draft animal at this weight interacts with terrain.

Groudon

Groudon weighs 950.0 kilograms and is about 3.5 meters tall. It is designated the Continent Pokémon and is associated with volcanic activity and drought, which is reflected in its thick red plates and geologic motifs.

In ‘Pokémon Advanced Generation’ material and later specials, Groudon’s movements alter ground features and displace water in coastal scenes. The scale of the environment changes around it match the mass found in its official entry.

Eternatus

Eternatus weighs 950.0 kilograms and measures around 20.0 meters in length. It is a Dragon and Poison type whose energy core drives the phenomenon known as the Darkest Day, and it changes to an even larger form under certain conditions.

The ‘Pokémon Journeys’ arc that resolves the Darkest Day shows capture attempts and stadium scenes that must contain a mass on the order of a metric ton. Reinforced platforms and specialized devices are depicted to manage its size and weight during the climax.

Primal Groudon

Primal Groudon weighs 999.7 kilograms and stands near 5.0 meters tall. This is Groudon’s powered form that appears when it absorbs natural energy, which adds larger plates and magma like channels across the body.

In crossover features such as ‘Hoopa and the Clash of Ages’ and in game related tie ins that reached the anime, Primal Groudon’s steps send fractures across prepared surfaces. Summoning sequences place it among other Legendaries with staging that matches the near one ton figure.

Cosmoem

Cosmoem weighs 999.9 kilograms with a tiny diameter of about 0.1 meters. It is the intermediate form in the Cosmog line and remains largely stationary due to its extreme density and compact structure.

‘Pokémon the Series: Sun & Moon’ follows Cosmog as it evolves into Cosmoem before reaching its final form. Characters attempt to move Cosmoem using containers and platforms that can bear nearly a metric ton, and shots consistently treat it as an object that cannot be lifted by hand.

Celesteela

Celesteela weighs 999.9 kilograms and stands about 9.2 meters tall. It is an Ultra Beast with a bamboo rocket like body and long nozzles on its arms that provide thrust during liftoff.

In ‘Pokémon the Series: Sun & Moon’, Celesteela is found embedded in the ground and later guided through a safe launch. The extraction and takeoff scenes use cratering and soil collapse to show how a one metric ton frame leaves the surface.

RX-78-2 Gundam

The RX-78-2 Gundam has a listed full weight of approximately 60.0 metric tons and a standing height near 18 meters. This prototype mobile suit uses a Luna Titanium alloy frame and carries equipment such as a beam rifle and shield that are accounted for in the full mass figure rather than the empty weight.

In the original ‘Mobile Suit Gundam’ television series and compilation films, the RX-78-2 appears in ground and space operations where support vehicles and carriers are scaled to handle a machine of this mass. Hangar scenes, launch catapults, and recovery sequences consistently show infrastructure suited for a sixty ton combat unit.

Godzilla Earth

Godzilla Earth in the anime film trilogy is documented at well over one hundred thousand metric tons with a height that reaches hundreds of meters. This incarnation is a plant based organism with metallic tissues known as Godzillium and it grows over millennia into the largest Godzilla depicted in animation.

Across ‘Godzilla: Planet of the Monsters’, ‘Godzilla City on the Edge of Battle’, and ‘Godzilla The Planet Eater’, military hardware and city scale defenses are deployed to engage a target of this mass. The films present artillery, fortifications, and specialized nanometal systems built to withstand strikes and vibrations produced by a kaiju measured in five figure tons.
