Pacific Rim: Kaiju and Jaegers

The purpose of this article is to provide some understanding of the Kaiju and Jaegers in Pacific Rim. The concise information provided below is taken directly from wikia.

For my review of the film, please visit the link below:

 Kaiju 怪兽 : literal translation - strange beast

The Kaiju are a race of amphibious beings from another dimension. In 2013, a portal between dimensions opened at the bottom of the Pacific Ocean ('The Breach'),  allowing them to enter Earth's dimension.
Each Kaiju is classified under five different categories:

Categories 1 through 3 presumably represent the weakest of the Kaiju;
Categories 4 through 5 are the strongest.

The Scale measures water displacement, toxicity and ambient radiation levels given off by their bodies when they pass through the breach. The fluid of a Kaiju is ammonia-based. Upon decomposing, their bodies release a noxious agent into the air known as "Kaiju Blue", their blood. Kaiju Blue has the ability to contaminate the air, making it non-breathable. The blood of a Kaiju is highly acidic, corroding anything in its path.

There are 9 Kaiju chosen and designed for the film.

 Category: Unknown - First Contact

'Trespasser' - Axe Head

The first Kaiju to make itself known to humanity, arrived in San Francisco and attacked the city, destroyed the Golden Gate Bridge and all on it, before the US military was able to take it down with a nuclear weapon. Estimated to be about 300 feet tall. It has a large axe-like crest on its head. It has four huge legs and a massive tail, and has orange breath, which resembles sparks and smoke.

 Category 2


Onibaba is responsible for the destruction of Tokyo, Japan, as well as the death of millions of citizens. Mako Mori was one of the few remaining survivors. Jaeger Coyote Tango was deployed to defeat the Onibaba. During the battle, one of Coyote's pilots blacked out due to cancer related issues, Stacker Pentecost was forced to ride Coyote solo and kill it himself.

 Kaiju Specifications - Unknown


Category 4 Kaiju that appears together with Leatherback, Otachi appears to walk on all fours, instead of standing upright like some other types of Kaiju.
Her anatomy consists of two short legs and long four digit hand-wings which she can use to fly. Her wings are stored inside her forearms for protection. In addition, she has a long tail which has vibrant blue circles that run on the side up to her chest as well as sharp pincers on the end of her tail. The facial structure of Otachi is made up of a long neck, and her head includes a large, powerful jaw and is marked by two crests.
Otachi is capable of spitting acids that capable of melting metal armor of Jaegers and breathe in space, when she takes Gipsy Danger high into space after a battle in Hong Kong.

Category 4 Kaiju that appears together with Otachi, Leatherback looks similar to a leatherback turtle but similar to the way a gorilla moves, walking on its knuckles with jumping abilities and large shovel like hands.

Category 4 Kaiju. It protects the portal from the Jaegers alongside Slattern and Raiju. Scunner's body shape is very similar to the Knifehead, albeit its different shaped head and much greater size. It has a bioluminous glow throughout it's body, however unlike the other Kaiju, it's glow is green. Broad and stocky, Scunner's strength lies within his its two curved horns jutting out of its head, large claws and multiple arms. It's ability to work in tandem with other Kaiju make it a particularly dangerous foe in combat.

Category 4 Kaiju. It protects the portal from the Jaegers alongside Slattern and Scunner. Raiju resembles a grey Iguana or crocodile in terms of shape and swimming technique. The Raiju is heavily armored along its back and head, which is actually a carapace encasing the creature's real brightly colored and soft head for protection. Slained by Jaeger Gipsy Danger.

 Category 5


First and only known Category 5 Kaiju ever encountered by humanity. The largest, most dangerous and strongest of all the Kaiju, Slattern is unrivaled by any of its brethren or Jaegers combined. Slatterns had thick leathery skin and three tails, the latter of which can be used as whips against their opponents. Slattern's body is extremely resilient against attacks and strong enough to survive from a nuclear blast at ground zero. Slattern's high toxicity levels and intelligence makes him the most lethal Kaiju ever fought by humanity and its impressive size is capable of dominating most of its enemies.

 Jaeger : German translation -Hunter

A Jaeger is a special type of mobile exoskeleton weapon, a mecha controlled simultaneously by each of its two to three pilot teams, equipped in a type of specialized armor that interfaces with machine. The pilots' very minds are locked in a neural bridge to control its every movement in the field of battle. Jaegers was introduced as a more efficient way of killing the monsters without the use of nuclear ordinance and serve as the primary defensive measures against the Kaiju in the Kaiju War.

All Mark-1 through Mark-3 Jaegers utilized nuclear reactors which put their pilots at extreme risk of developing cancer. Of the 21 Jaegers built, only 4 remain in active service as of 2025.
