Probably the fastest slug to date, the Ostrich leave it's rider exposed to enemy fire like the other animals, but it compensates with his speed and high jumping ability, able to jump over large chasms with ease. It comes equipped with a 12.6mm Vulcan, but it only fires in an 180° arc. It's the only animal slug that turns, which takes some time, time that can kill the rider if he is not careful. Attacks from above and lobbing attacks are the bane to the rider.
- It also appears in Metal Slug Defense as unlockable unit.
