They're colored in pinkish-red, and their mouths are stitched shut, removing their ability to fire shots; Instead of firing blood shots at Isaac, they float towards him at a higher speed than regular Maws. They explode into a plus (+) pattern of blood shots when they die.
- Red Maws fire larger blood shots upon death if they're champion variants.
- From the original game, they use to make a sound upon death with a same audio as the Maw (while firing shots). In Rebirth, the sound was obviously missing.
