Batalia

Batalia is home to Fort Krontos and was invaded by Drek during his campaign to create a new homeworld for the Blarg.

Ratchet & Clank
Ratchet and Clank arrive at Fort Krontos and are immediately grilled by the sergeant they saw on the Infobot on Umbris. The sergeant demands that Ratchet and Clank get into the fort and destroy the Blargian bombers that are seiging the area with the fort's turret. Ratchet reluctantly argrees. However, when the reach the fort's perimeter, the fort's bridge had been withdrawn and the bolt crank to draw the bridge was on the otherside. The sergeant tells Ratchet to figure out a way to utilize the nearby air duct to get into the base and then gives Ratchet and Clank an Infobot containing coordinates to planet Orxon before leaving to find his squad. Ratchet agrees that he and Clank can return later once they find something that will let them walk the duct into the base.

Before leaving Batalia, Ratchet and Clank run across one of the deserters from the sergeant's squad. He offers an Infobot to the duo if they'll give him money for busfare. They pay his asking price of two thousand bolts and with the Infobot acquire coordinates to planet Gaspar.

After Clank finds a pair of Magneboots on Orxon, the two return to Batalia and enter the fort using the air duct. When they reach the turret they meet the same plumber they met on Novalis, to their surprise. He says that he's in charge of fixing up the turret, though no one around actually knows how to use it. Ratchet offers and, though the plumber is reluctant, he concedes and lets Ratchet shoot down the bombers. As reward, the plumber gives Ratchet a Metal Detector which lets the user suck up bolts that are buried underground. With that, the two leave the planet once more.

Appearance
From orbit, Batalia is a very dark blue without many notable features, suggesting the planet is primarily oceans dotted with small islands.

The surface around Fort Krontos suggests much of the same, with little actual land mass and many supported artificial structures. The structures themselves being severely damaged due to the bombardment the fort experienced during the Blargian invasion.
