Basilisk Leviathan

Basilisk Leviathans were flying territorial behemoths that put up a tough fight. They had a spitting attack that they could launch from a moderate distance, as well as an elecrtical, full body charge and a shock bubble drop that dispensed several bouncng balls of crackling energy that could zap Ratchet on contact. Ratchet had to keep these foes in sight at all times, avoiding their attacks at all costs, and sending off a stream of continuous fire until there was nothing left but a few shards of Raritanium and a valuable Leviathan Soul.

In A Crack in Time, in the Insomniac Museum, another type of Leviathan could seen through the windows, only golden in color.There was also a model of the Leviathan in one of the rooms.The only difference was that the one in the museum was greewith a yellow tail.
