VoG Goku could instant transmit out. He could also just rip the door off the VoG to skip that part. He'd have difficulty understanding oracles at first but wouldn't even need the Aegis to kill Templar. He'd be caught by gorgons but kill them before they wipe him. He'd skip the jump puzzle. Gatekeepers a breeze for him cause he doesn't even need to open the portals. And then Atheon ain't got shit on him.
