Tatsumaki vs. Psykos

You are indeed someone I must deal with personally, Tornado of Terror, the esper prodigy...!

Tatsumaki vs. Gyoro Gyoro was the battle between the S-Class hero Tatsumaki and the Monster Association's military adviser Gyoro Gyoro.

Prelude
Gyoro Gyoro is on the throne, thinking about the battle situation, when Tatsumaki appears at the monster's side, asking if she's worried about the cadres being wiped out. Tatsumaki then asks Psykos if she is the boss. The monster welcomes the hero, and states that Tatsumaki is someone that she must take care of personally. Psykos introduces herself to Tatsumaki, explaining her position as the military advisor of the Monster Association, and sadistically tells the female esper to drop dead as she uses her psychic powers to pelt and surround Tatsumaki with several boulders.

Battle
As Gyoro Gyoro surrounds Tatsumaki with these rocks, she attempts to compact the rocks into a small sphere and crush Tatsumaki, but the female esper effortlessly breaks free, deriding Gyoro Gyoro for her weak psychic abilities. Tatsumaki sends several rocks flying at Psykos, who barely manages to put up a psychic barrier in time, although Tatsumaki manages to break through her psychic barrier and take the monster's arm off in the process.

Seeing the danger she's in, Gyoro Gyoro decides to use her maximum power and fight with her true form. As she unleashes the full extent of her power, her body increases several times in size, and several eyes begin to pop up on several parts of her body. Gyoro Gyoro declares herself as the superior esper and for Tatsumaki to enjoy this to her heart's content.

Gyoro Gyoro proceeds to use her psychic powers to surround Tatsumaki with high gravity waves, sadistically saying she will turn the esper into a dried persimmon. However, Tatsumaki is practically unaffected, mockingly saying that the gravity waves were loosening her stiff shoulders she'd gotten from switching to a new pillow. Gyoro Gyoro is helpless as Tatsumaki goes on the offensive and rips off all of Gyoro Gyoro limbs, causing the monster to bleed profusely. After her body is ripped apart, Gyoro Gyoro laments how much she'd underestimated Tatsumaki's abilities until fighting her face-to-face. Gyoro Gyoro admits her defeat to Tatsumaki, but also says that the esper was particularly cruel with her dismemberment. However, Tatsumaki knows the truth: what she'd fought was merely a meat puppet being controlled by the real psychic, and confidently says she will pull her real body out. Gyoro Gyoro is shocked that Tatsumaki was able to see through this, and states that fighting her was premature. Left with no other option, Gyoro Gyoro calls out to Orochi to save her. Tatsumaki remembers that name mentioned before, and Gyoro Gyoro asserts that while she's the military advisor, Orochi is the boss of the Monster Association and that even as his creator, she cannot accurately gauge his power.

Gyoro Gyoro wonders why Orochi is not coming to assist her, for she managed to obtain absolute control over him from years of brainwashing during his transformation as a monster. Tatsumaki suggests that Orochi is engaged with one of the S-class heroes, who while nowhere nearly as powerful as her, are still quite strong according to her. Gyoro Gyoro ponders this possibility and is frightened at the thought of a hero strong enough to occupy Orochi and take priority over Gyoro Gyoro's wellbeing. Powerless and alone, Gyoro Gyoro starts to beg for her life.

Trivia
As Orochi does not exist in the Webcomic, Gyoro Gyoro does not call for him in it either.
