The Medusa Minosaur (メデューサマイナソー Medyūsa Mainasō, 3) is a gorgon-based Minosaur monster from the Warfare Tribe Druidon.


After the defeat of the Unicorn Minosaur, Kleon finds streamer Ui Tatsui videoing the fight and infects her with his slime with the Medusa Minosaur being created from the negative emotions generated by her desire to be seen and acknowledged by others on the internet. The Medusa Minosaur is first seen trying to petrify people in a plaza where it is confronted by Koh, Melto and Asuna who morph and fight it. However, it is a match for them and manages to petrify Koh though Melto saves Asuna from the same fate. Even so, thier inability to look directly at it prevents them from fighting properly though the arrival of Bamba with the MabushiSoul to blind it and prevent a finishing strike. Before he and Towa can attack it however, Drunn Soldiers appear thanks to Kleon not wanting his new creation destroyed. With the Ryusoulgers preoccupied, the Medusa Minosaur leaves which Bamba tries to prevent but the intervention of Tankjoh allows it to retreat and Ui is put into a coma soon after.

The Medusa Minosaur later returns to Tokyo as a giant who rips through the street so Koh (freed from the petrification by Bamba and the MistSoul) and Melto have to fight it whilst Asuna finds an escaped Ui. As its host gets even weaker, the Medusa Minosaur is able to grow even larger and much of the city via a news-feed. Koh forms KishiryuOh to fights the Medusa Minosaur but struggles to hit its since he has to fight whilst covering his eyes. Using Kishiryu Triken and Kishiryu Ankyloze, they create rubble from the street and then, with a combination of the Karu and GyakuSoul, succeed in covering the Medusa Minosaurs' chest eyes. They then form KishiryuOh Three Knights which the Medusa Minosaur finds itself helpless against and is destroyed by the Final Blade attack.


Like all Minosaurs, due to being created from pure negative emotion based upon a singular desire, the Medussa Minosaur was only capable of saying "look."

Powers and Abilities


  • Negative Emotion Empowerment: The longer that the Medusa Minosaur existed, the more negative emotions it gained and would grow more powerful until it became a Full Body Minosaur.
  • Petrification: From the eyes on its chest, the Medusa Minosaur could emit purple lights that could turn anyone to stone.
    • Screen Petrification: The Medusa Minosaur was even able to indirectly petrify its enemies as seen when she petrified a large crowd through a news broadcast.
  • Enlarging: The Medusa Minosaur was able to enlarge itself by absorbing its host's negative energy.
    • Hyper Enlargement: The Medusa Minosaur was able to absorb more negative energy from Ui to grow even larger.


  • Skilled Fighter: The Medusa Minosaur was able to fight and match all three Ryusoulgers in battle with its kris.


  • MistSoul: The MistSoul was able to undo the Medusa Minosaur's petrification as seen when Bamba saved Koh.
  • Covered Chest Eyes: When the eyes on her chest were covered by a large object, the Medusa Minosaur was unable to use its power.


  • Cobramberge (コブランベルジュ Koburanberuju): The Medusa Minosaur wielded a kris-style blade for combat.
    • Energy Empowerment: The Medusa Minosaur could charge light blue energy into its blade to slashes its enemies at full force.
    • Energy Wave: The Medusa Minosaur could generate an orange energy wave from the Cobramberge. This was strong enough to cute a building in half and create a massive explosion but didn't faze the Kishiryu.
