The Rebel Gigant is the sixth boss from Metal Slug 7.
A huge mech that developed by future rebel army that bought into present days. it specifically designed to be controlled by Demon Seargant.despite of huge body and has very tough armor it has great agility.it also equipped with various weaponry such as Homing missiles, and Floating mines.
Its attacks vary from firing rockets from the shoulder to jumping off screen and sliding into the player's Gigant. It is fortunate that death here allows another Slug Gigant to be employed after respawning (the Slug Gigant's destruction kills the player), as the Rebel Gigant would easily defeat the player otherwise. Note however it is possible to fight and defeat this boss on-foot using nothing but a pistol through a War Room mission.
