- Fires 4 lines of 4 curving blood shots.
- Fires 4 lines of 7 waving blood shots.
- Fires 10 lines of 4 blood shots in all directions.
- All the attacks of the Red version do 1 heart of damage.

Concept art for Mega Maw (known in this sketch as "Mr. Maw Mega"), along with a scrapped variant of Pin and what is presumably an earlier version of The Gate.

It is the boss version of the Maws.
The Gate is the posthumous version of it.
Before its fire attack, a purple flame can be seen emanating from its forehead.
Despite its name, it acts and looks more like a Horf (or a Psychic Horf) than a Maw, because it does not move and its eyes are more round.
Its fire attack could be a reference to Mega Man's leaf shield/attack.
