Cruiziler (クルージラー?) is a large whale cruiser Mechaniloid that appears in Launch Octopus's stage in Mega Man X and Mega Man Xtreme 2. It shoots bombs that fall slowly and releases Sky Claws. When destroyed, it will sink--one of which will break open a floor leading to a hidden power-up protected by a Utuboros. Its name is possibly a combination of the words cruiser (クルーザー) and whale (クジラ kujira).
An effective way to sink the Cruiziler in Mega Man X is to use Fire Wave on its weak point. This will not only sink the vessel quickly, but also immediately destroy all Sky Claws as soon as they emerge from the top.
