|Megaleg, as it appears in Super Mario Galaxy|
The Megaleg is a recurring boss in the Mario series, first appearing in Super Mario Galaxy. It is a giant, three-legged robot with a face resembling a Snifit, armed with Bill Blasters to fire Bullet Bills. It was supposedly built and commanded by Bowser Jr. Mario battles it for a Grand Star in Bowser Jr.'s Robot Reactor.
Super Mario Galaxy
Megaleg first appears in Super Mario Galaxy, where Mario must battle it to get the second Grand Star and further power the Comet Observatory. It is encountered in Bowser Jr.'s Robot Reactor during the mission "Megaleg's Moon". When Mario arrives, Bowser Jr. appears on an Airship to taunt Mario before summoning Megaleg and flying away. The robot them makes its presence known, and begins attacking Mario.
Initially, Megaleg will move around the small planet, trying to squish Mario with its legs, which can instantly take a life. It can also fire Bullet Bills from multiple parts of its body, including its head, legs, and underbelly. Mario must climb up the legs and platform his way to the top of the head, where the Grand Star is being kept in a glass container. Mario must lead a Bullet Bill into the container to destroy it. This, however, sets off an alarm, and causes several spinning gates to appear around another container. Mario must break these gates with Bullet Bills so he can break the new glass container. This will ultimately defeat Megaleg, causing it to dismantle its own parts as they all explode. Mario can then take the Grand Star.
Megaleg appears in Super Mario: Battle of the Stars as an unlockable playable character.
Megaleg appears in Jake's Super Smash Bros., being used for Bowser Jr.'s Final Smash, replacing Shadow Mario Paint from previous games. Bowser Jr. will summon it as it stars attacking opponents. It can either fire Bullet Bills that home in on them or stomp on them with its legs to damage them. After awhile, Megaleg will disappear.
Megalegs are also appears in Nintendo's War of The Worlds, it has a weaponry, Heat Ray and Black Smoke.
