Can Goku still Solo? (Read body text)

Can Goku win through all his martial arts and skills (and a few tricks) alone?

In these matchups, Goku will be at the peak physical condition for his weight class (210 lbs, since that is a more realistic, but if you wanna take his official weight of 137 lbs, be my guest), with no Ki attacks, Saiyan transformations, TUI, or MUI. I am willing to allow him to use a few of his abilities (The Kaioken, Instant Transmission, and being able to use Ultra Instinct in base form, as he’s been shown). Can he beat every opponent?
