Tenshinhan is taken aback to learn that Goku is already utilizing a 10x Kaiō-Ken, feeling that he's doomed. Meanwhile, Kaiō reflects on how Freeza isn't even tapping into half of his actual power, recalling his earlier warning to keep their “hands off Freeza no matter what,” and realizing that everything has come to an end.
In the midst of this, Goku considers the possibility of using a 20x Kaiō-Ken. He weighs the risks, knowing his body might not withstand it, but realizes that if Freeza is truly only at 50%, he’s in deep trouble regardless.
Ultimately, he decides he must take the risk, hoping that Freeza is just putting on a show. Suddenly, Goku unleashes an incredible surge of energy, catching Freeza off guard.
