Megachomp

The Megachomps (or Stargolems) are magical creatures introduced in Season 8.

Overview
The Megachomp are creatures made out of darkness and is controlled by Valtor. They are also the henchmen of Obscurum. Their proceeding form is Starchomp. Their normal form is Staryummies.

Appearance
They are dark blueish-purple in colour, and have small, bright, white specks which resemble stars. They appear to be furry, and have gold-orange eyes. Unlike its lesser form, have larger, bulkier and muscular bodies with dumbbell arms and legs. They have large mouths with sharp white teeth, showcasing a ferocious disposition.

Season 8
In "Surprise Party on Earth"' Valtor summons many Staryummies to attack the core. Though they join into Starchomps, they still undergo retaliation until they form into the Megachomp which quickly intimidate the Sun's Lumens before punching and swallowing the star core. The Winx try to defeat it though it proves resistant to their attacks.

In "Valtor's Shadow", they continue to engage in combat with the Winx, though Tecna's attacks manage to split them back into their composite Starchomps which retreat into shadow portals. At the same time, the Sun's energy gets released though without it's core.

Magical Abilities
Megachomps rely on brute strength rather than magical attacks. They also can extend their arms to attack opponents from a far distance. They do have the ability to drain star cores of their light and are also resistant to most types of magic except for light-based sources.
