The Ultrathermal Flamestrike Projector is a weapon used by Meta Ridley. Oftentimes he will fly into the air, and as he descends, his feet become engulfed in flames and he promptly slams the ground of the Artifact Temple, creating waves of flame energy that will hit Samus if she does not timely jump over them. When in his ground form, Meta Ridley will perform this attack more often. This attack is never used in the original NTSC version of Metroid Prime. Meta Ridley's corrupted form, Omega Ridley, seems to use a variation of this attack in Metroid Prime 3: Corruption.
