Lombax

The Lombax are a bipedal, humanoid species that originated in the planet Fastoon in the Polaris Galaxy. They are known throughout the galaxy for their mechanical and technological ingenuity, given how they have an innate affinity towards gadgetry and machinery.

Appearance
Lombaxes are cat-like and completely covered in either yellow or white velvety fur, with orange or maroon coloured stripes running down parts of their body. They had large ears and triangular feet with three claws on each foot, as well as large hands with five fingers. All known Lombaxes wore gloves, so it was possible that generally most Lombaxes wore gloves.

According to a news broadcast in A Crack in Time, female Lombaxes did not have tails, as evident with Angela Cross.

Great War
The Lombaxes originated from the Polaris Galaxy. Years ago, they fought a Great War against the Cragmite empire, being the only independent force capable of challenging them due to their engineering prowess. During the conflict, at least one hundred Lombaxes were killed by Zorthan, who fought alongside the the Cragmites. The Lombaxes were hailed as the saviors of Polaris after defeating the Cragmites once the War had reached a stalemate. However one Cragmite, Percival Tachyon, survived. The Lombaxes discovered him as an egg in Lombax Trillium mines and raised him as one of their own on Fastoon. However, once he found out that he was a Cragmite, Tachyon raised an army against the Lombaxes in the rage that his true origins were hidden from him.

Escaping Their Dimension
Taken by surprise, the Lombaxes tasked a mapper named Mags to locate another dimension where they could hide away in using a device called the Dimensionator. Alister Azimuth was forbidden from joining them due to his involvement in Tachyon's rise to power. While many Lombaxes were able to avoid being destroyed by Tachyon, others were killed in the conflict trying to escape. Kaden stayed to protect the Dimensionator and sent his infant son Ratchet to the Solana Galaxy to keep him safe. Tachyon eventually killed Kaden after tracking him down an unspecified time later.

The Lombaxes' Legacy
As a result of Tacyhon's onslaught, only Ratchet, Angela Cross, and Azimuth were the last known surviving Lombaxes in their dimension. At some point, Angela traveled with Max Apogee to the Polaris Galaxy to escape Tachyon's persecution, before they both disappeared after escaping the Cerullean Sector. The dead Lombaxes were eventually avenged by Ratchet upon defeated Tachyon and preventing the Cragmites from returning to their native dimension. During the ordeal, Ratchet got a glimpse of the dimension the surviving Lombaxes were inhabiting through the powers of the Dimensionator.

Ratchet eventually met Azimuth, who wished to use the Great Clock to rewind time correct his own mistakes and bring the Lombaxes back. However, upon learning that the Clock was meant to keep and not alter time, Azimuth stopped the Clock in its tracks, dying in the process. This left Ratchet as the last known Lombax in the universe.

Ratchet had another chance to be reunited with his race after Vendra and Neftin Prog created a replica Dimensionator to bring the Nethers back from a dimension known as the Netherverse. However, the Progs' plan went sideways because of the Nethers' ulterior motives. With the replica Dimensionator lost, Neftin sought Ratchet and Clank's help in rebuilding the original Dimensionator to rescue Vendra and banish the Nethers back to the Netherverse. In the end, Ratchet declined to use the Dimensionator, not wanting to risk the life be build in his own dimension to go and join the Lombaxes.

A Possible Reunion
Clank secretly retrieved the broken Dimensionator and rebuilt it into a handheld device, which he presented to Ratchet during a parade in their honor years later. However, the device was stolen by their arch nemesis Dr. Nefarious and took significant damage, causing dimensional rifts to open randomly. The three were transported to a universe where Nefarious' counterpart became emperor of the Polaris Galaxy and the Dimensionator violently exploded, thereby damaging the fabric of space and time.

While seeking to build a new Dimensionator, Ratchet and Clank are joined by Rivet, a female Lombax with a robotic arm who is part of a resistance seeking to free the galaxy from Emperor Nefarious' rule, and Kit, a former warbot created by the villainous emperor. After building the Dimensionator and defeating Dr. Nefarious, Emperor Nefarious steals the device to use in his conquest. After seemingly defeating all of his enemies, Emperor Nefarious began preparing to invade other dimensions, starting with Ratchet and Clank's home dimension.

Backed up by Rivet and the Resistance, Ratchet and Clank pursued Emperor Nefarious to their dimension and destroyed his giant power suit. Though she was initially hesitant in being someone's partner, Kit eventually decided to fight alongside Rivet. Ratchet, Rivet, and their allies eventually manage to defeat and banish Emperor Nefarious through a rift. Recovering the Dimensionator, Clank repaired the dimensions and averted the Dimensional Cataclysm. At some later point, Ratchet, Clank, Rivet, and Kit used both the Dimensionator and a Dimensional Map that Mags designed long ago to locate the Lombax dimension.

Culture
Lombaxes were very capable fighters with natural skills. The Lombax Praetorian Guard are the elite warriors of the Lombax people. General Alister Azimuth is the only member who has been featured in the canon, with the rank of 4-Bolt Magistrate. Ratchet's father Kaden may have also been in the Guard due to his staying behind, but this is never confirmed nor denied. The weapons they use are unknown, but it can be inferred that wrenches are used for close-quarters combat. The Guard can presumably be recognized by their Trillium Armor.

In addition to their combat skills, Lombaxes were known throughout the Polaris Galaxy for their advanced technological knowledge, and rarely used unmodified equipment. There were several Lombax groups devoted to developing such technology, including the Center for Advanced Lombax Research. The Lombaxes created various hi-tech gadgets, weapons and armor through the use of their facilities.
