Push
Two things were going on at once when fighting against Athos. After the two of them had decided to approach the Celestial from the opposite direction, Sil used his fast speed to sprint straight towards Athos.
"I must admit, you are much bigger than any other Celestial I have fought against, but size doesn't mean you are stronger!" Sil shouted.
Just like with Quinn, the female golden Amra had decided to interfere in the fight and swung her swords down, but when it looked like Sil was about to get hit by the incoming attack, he disappeared from his spot.
And in the next instant, he appeared on top of her head.
He lifted his leg high, and with it, he had created a tornado of flames. Then, without hesitation, he slammed the kick on the female Amra. The fire quickly spread, and it looked like her whole body was about to be consumed in flames.
