All Bosses In Super Mario Galaxy
Bowser is known as the villain of the Mario series.
He's obsessed with Princess Peach.

Dino Piranha is the first boss encountered in the game.
He's found in the Good Egg Galaxy.
His lair is on the Dino Geo Planet and Mario will wake him by accident by hitting the egg.
ROARANHA: There is a boss similar to Dino Piranha in Super Mario Galaxy 2 called Peewee Piranha
Megaleg seems to be based on a Snifit (the red enemies that look like they have a gas mask on).
He barely fits on his home planet due to his size.
He has three tripod-like legs which contain traps that prevent Mario from reaching its head.
The Grand Star is trapped in a cage on top of Megaleg's head.
SNIFIT BOSS: The earliest version of Megaleg was labelled "BossCrab"
Bouldergeist makes an appearance in both Super Mario Galaxy and Super Mario Galaxy 2.
He is located in the Ghostly Galaxy.
The Bouldergeist throws three different types of rocks.
Golden rocks give you a coin. Regular rocks and grey/black rocks throw Bomb Boos.
If he's hit three times with a bomb boo. he will get new armour and grow arms.
Mario can destroy these hands but they will regenerate over time.
ROCK & ROLL: Bouldergeist's name is a combination of "boulder" and "poltergeist" meaning "Ghost Boulder"
King Kaliente is an orange octopus with a crown on his head.
Some of his body is submerged in lava.
He will shoot fireballs and coconuts at you.
It only takes three hits to knock him down.
WHAT'S KRAKEN?: King Kaliente's name comes from the Spanish word caliente, meaning "hot"
Fiery Dino Piranha
Fiery Dino Piranha is the boss in the Melty Molten Galaxy.
This is the final level of the galaxy.
He must be defeated to get a Power Star.
He's almost identical to Dino Piranha but has different colours and can shoot fireballs.
Hit it four times with its tail and it will be defeated.
THIS DINO'S ON FIRE: Fiery Dino Piranha's tail sometimes catches on fire in the fight
