Cruiziler (クルージラー Kurūjirā) is a large whale type maritime security 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. Cruiziler can only be damaged on the core on its top. When destroyed, it will sink--one of which will break open a floor leading to a hidden Life 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.
