Kalebo III is a planet in the Solana Galaxy featured in Ratchet & Clank. It is most notably home to the Gadgetron site, and the headquarters for Gadgetron Corporation, making it a hub for the production of weapons and gadgets. The planet itself is covered in lush islands surrounded by vast oceans, on which the Gadgetron site is constructed.
Ratchet and Clank arrived in search of the Hologuise, a gadget that would allow them to sneak by Sentry-bots. However, Chairman Drek sent his most elite troops to hunt them down, and attacks the site.
Ratchet and Clank received coordinates for Kalebo III on planet Quartu from an infobot given to them by the Ultra-Mech Scientist, after destroying several Ultra-Mech Unlimiteds. The infobot contained a commercial for the Hologuise, which would allow them to infiltrate Quartu's factory by sneaking past the Sentry-bots. When they traveled to their destination, Drek sent his most elite troops to attack the planet in search of them, telling them that he would be happy for them to destroy Gadgetron if it meant killing them.
When they arrived, the Gadgetron site was under attack by the blarg in search of Ratchet and Clank. After fighting through the blarg to reach the Gadgetron CEO, he seemed aloof about the situation, saying that Gadgetron's defenses were top notch and he was unfazed by the attack. After they asked him about the Hologuise, he said that the device was unavailable, but could still be won as a prize for the hoverboard race. Ratchet and Clank competed with their hoverboard, and won the race. The CEO asked them to film a commercial endorsing Gadgetron's latest hoverboard, to which they obliged. He also told them that they could receive an employee discount if they stayed with Gadgetron for two years.
Kalebo III is covered in small islands surrounded by fast oceans, on which several large Gadgetron buildings are featured. The buildings typically feature large green windows and grey metals, with dozens of flying cars surrounding them presumably transporting goods. The world also features sets of trains transporting goods.
The Gadgetron site contains a lobby, the HelpDesk office, the CEO's office, and also an employee break room. Several large rooms are filled with Test Dummy robots that test Gadgetron's weapons, including testing the Bomb Glove, the Pyrocitor and the Walloper. The Test Dummy robots also race on the Gadgetron hoverboard race track against Ratchet. During Ratchet and Clank's visit to the employee break room, it was filled with chickens.
Behind the scenes
Despite the planet's islands being surrounded by water, when Ratchet falls into it, the death animation used is the one in which he falls through air, rather than him being eaten by a sharkigator.
Underneath the water, the race track for the hoverboard race is clearly visible to the player, but out of reach. This is because the hoverboard race is loaded in below the main level (as is the race in Rilgar), though the developers did not obscure it from vision. This is referenced in the 2016 re-imagined game, where the race track's visibility is intentional, and the CEO before the race instead drains the water around it when the races begin.
In the Platinum PAL release of the game, the Gadgetron tower instead had "Galactron" written around it.
