Lava Release

The jutsu are techniques that combine fire and earth-based chakra to create a torrent of lava that can melt away almost anything. It is used by the Fifth Mizukage.

Without the Kekkei Genkai
Though not possessing the kekkei genkai, Rōshi is able to use Lava Release techniques due to being the jinchūriki of the Four-Tailed Monkey. It is unknown to what extent the Four-Tails' Lava Release is the same as the Fifth Mizukage's.
