The bizarre time-space power of King Sofia Goldrass rendered Dyna's attacks ineffective. No matter how strong his power or mysterious abilities were, they could be neutralized with the opponent's time-space power.
Simply put, when a punch is thrown, the surrounding time-space distortion prevents the fist from reaching its target; when an Energy Bullet is fired, the opponent can twist its trajectory back to its origin using time-space distortion.
In three words.
Receive!
Neutralize!
Redirect!
If not for the fact that King Sofia Goldrass's mastery of time-space distortion was still unstable, even physical attacks unleashed through fists and feet could be returned.
As for why energy is easier to return than physical matter.
It's a simple principle: in space-time transfer, energy blasts have immense destructive power, but energy components are singular; physical attacks like punches and kicks have less destructive power, but Ultraman's body is more complex.
