Observations

'Just as I thought, it truly has gravitational force,' Gustav analyzed as he moved towards Charles's back and tried to touch him.

Due to the usage of dash, Charles was still moving in slow motion, but his eyes were able to follow Gustav.

Charles wanted to change the direction of his attack to Gustav's new location but even though his eyes were able to follow, his body movements were still slower.

Gustav arrived behind him and pushed out his palm to touch Charles's back.

Zhhooon!

When Gustav's palm was three inches away from touching Charles, it paused and was unable to move forward.

Gustav was astonished but not surprised cause he already sensed the force surrounding Charles that repelled any form of contact.

Charles turned around and hurled his fist coated in electric snakes towards Gustav's chest.

Gustav dodged it of course and dashed backward.
