Helmasaurus

The Helmasaurus is a Twilight Princess original enemy that appears in the City in the Sky.

The Helmasaurus is a differently colored and much larger version of the Helmasaur. Like the Helmasaur, it also attacks by ramming into you with a forward charge. The iron plates of a Helmasaurus can't be removed like those on a Helmasaur, so getting behind and striking at its vulnerable backside is the only way to defeat them.
