The Overblast is an ability only appearing in Metroid: Other M. This technique allows Samus to leap upon an enemy, charge her beam, and fire it at close range at a vulnerable point on the enemy's body, inflicting a great amount of damage. In most cases, Samus can only use the Overblast to already downed enemies, and it can be used multiple times on a single enemy. It can also be used multiple times between two or more enemies, keeping Samus off the ground and above the enemies. Unlike the Lethal Strike, it cannot necessarily defeat enemies in a single shot, but because of its power, it can destroy certain enemies, such as Sidehoppers, in one shot and is effective when attacking certain bosses, such as Goyagma.
The attack is semi-automated. Once Samus jumps on an enemy's head (or another vulnerable body part), her beam charges automatically, and Samus must shoot. Once she shoots, she jumps off instantly, and the foe is pushed back or to the ground. If Samus does not shoot while she is on the enemy creature, the enemy may push Samus off. Different creatures will push Samus off at different times.
