Born after a failed experiment resulting from Rebel forces releasing their genetically toxic chemicals on plants, these voracious vegetables became ambulatory and carnivorous, capable of swallowing a human in one bite. In Metal Slug 3 and 7, the Man Eater will attack by striking out towards the player and attempting to eat them, resulting in the loss of a life. The Man Eater is also capable of eating more than 1 player in one attack. Sometimes instead of dying by being shoot, a Man Eater will transform into a tall plant with a bud which will spit deadly spores. Direct contact with one of these spores will turn the soldier into a mass of vines as they die. Otherwise if it contacts solid ground, a new Man Eater will grow from it.
In Metal Slug 7, a new variant of these carnivorous plants known as "Huge Ivy" is introduced during mission 4. Instead of walking, they stand still hanging from the ceiling waiting for a prey to come close. If this happens, the Fly trap will use its tentacles to catch the soldier, take it to its mouth and eat him. Even if the player manages to avoid the tentacles, standing right below the mouth is a bad idea since the fly trap can extend its stem and eat you as well. The best strategy is to keep a safe distance and shoot them with the help of the Slugnoid that is given at the beginning of this path.
- They were based on horror movies like Little Shop of Horrors.
- They also bear some resemblance to the Piranha Plants of the Super Mario Bros. series by Nintendo.
