I have an Insta account but only when I log into it through a browser. When somebody here posts a vid from Insta, I'm not logged in. It still plays fine.
Kind of seemed like a nod to Toriyama. Goku vibes with his warm up. The stance he had prior to it and then it seemed like that was added in last second. It only lasts a few seconds but it kind of gives me the Dragonball vibes.
