Chargers are a more advanced form of Maggot, and they're encountered more often as well, first appearing in Chapter 2 and then Chapter 3.
They resemble maggots with visible eyes and mouth. It is revealed that they have long teeth, as seen while charging toward the character.
They possess a smiling face of sorts, and look quite harmless as they slowly crawl along without attempting to follow Isaac. If a Charger lines up with Isaac vertically or horizontally without any obstruction, they will immediately and quickly charge in a straight line towards him. Because they're always encountered in groups of at least four, avoiding them can quickly becomes a problem.
Chargers do not seem to notice Isaac unless he is moving. If Isaac stands still and a Charger lines up with him, they will continue crawling without attacking him.
- Chargers can be spawned by Chub, Sloth, Pestilence, and Fistula (only upon destruction of smallest parts).
- They are also spawned upon the destruction of the Green Champion version of The Hollow's body segments.
- They appear in the original game.
