The guyver will bring the fight to him. Assume Goku tried just ki blasts, guyver will dodge until he鈥檚 in a suitable range to use his head beam, and the head beam is for both their benefit. They both need to see. Goku is quick enough to dodge depending on the distance. Now that he knows one of guyvers attacks that鈥檚 very dangerous, he fly further in the air for it Kamehameha. Guyver sees this, and not so wise to use, so he doesn鈥檛 stay stationary, and go for sound waves to prevent humanity destruction. Now Goku comes down in pain, and sho says sorry, I refuse beheading.🙏
