Spin Jump Attack

The Spin Jump Attack (or Charge Attack) is easily described as a "pseudo Screw Attack".

Samus has the ability to perform a damaging Spin Jump Attack when the Charge Beam is fully charged. It is used in conjunction with the Charge Beam and a Spin Jump. By somersaulting into an enemy, it will receive damage roughly equal to the charged current Beam. This attack can offer safety while dispatching enemies simultaneously. However, it cannot destroy every enemy, and if they are tough enough to survive the attack, Samus will receive damage as well. This attack can only damage a single enemy at once (with the exception of swarm enemies in Metroid Dread); if Samus comes in contact with another enemy before the Beam is charged, she will receive damage. The Spin Jump Attack is occasionally called an "early-game Screw Attack", because the former serves same purpose as the latter; therefore, this ability becomes obsolete when Samus acquires the Screw Attack.

In Super Metroid, the Spin Jump will be cancelled if a Wall Jump is executed with a Spin Jump Attack while holding the shot button, but this does not occur in later 2-D games. The Spin Jump Attack is impossible to perform in the Prime series, which is probably due to the first-person perspective, although the Screw Attack is usable in later Prime games. In Metroid: Other M, Samus does not possess this ability at all.
