Mastadoom

“Phew, I'm FREEZING...”

—Mastadoom, Super Mario RPG: Legend of the Seven Stars

Mastadooms are large skeletal mammoths encountered on Star Hill in Super Mario RPG: Legend of the Seven Stars. Mastadooms are possibly the most powerful enemy on Star Hill having an arsenal of physical attacks and the powerful "Drain Beam" attack which hurts all party members. Mastadoom's regular attack consists in hitting his opponents with his long trunk. Mastadoom is strong against Thunder, but his main weakness is Fire, which may seem surprising as Mastadoom is always shown in water.

Like most powerful enemies in Super Mario RPG (Reachers, Hippopos, etc.) more than one Mastadoom does not appear in battle, instead Mastadooms simply aid other creatures in battle. There's also a unused enemy named Mastablasta, which is a Blue Colored Version of Mastadoom.
