- Origin: Okutama-Nio mountain
All of the negative energy created by mankind had formed many monsters, but all of them were defeated easily by Ultraman 80. The negative energy attempted one last assault in the forms of Plazma and Minazma, who appeared from underground in a mountain region. After UGM could do nothing 80 went into action. The two monsters were using their beams to hold 80 at bay until they decided to go back to back with one another and fuse. While in this fusion, 80 used both the Saxium Ray, the Buckle Beam, and even the Ultra Straight Flash with absolutely no effect. 80 was nearly defeated until Yullian revealed herself and assisted 80. The two giants of light used the Double Power, destroying the negative energy's last real chance of defeating 80.
- Plazma's head was reused from Ghostdon.
- For unknown reason in Ultraman ZOFFY: Ultra Warriors vs. the Giant Monster Army, Plazma has a reused Magular roar.
- Powers and Weapons
- Burrowing: Plazma can burrow at medium speeds.
- Horn Beam: Plazma can fire a purple beam from his horn.
- Fusion: Plazma can fuse with Minazma back to back. In this form they can withstand multiple attacks from Ultraman 80 without even flinching or take damage.
