This is a pretty interesting fight. Both of these fighters surpass the power of a Super Saiyan and both were handily defeated when they went up against a Super Saiyan Super Attack or a Super Saiyan 2 Kamehameha. It’s a tough fight all right, but I would give it to Android 13. It’s possible that Bojack has a slightly higher power level, but Android 13 has a lot of speed on his side. He also went up against Goku directly instead of fighting his friends. Taking on Goku is always the toughest feat to accomplish! Android 13 wins.
Update 9 19 20 Bojack’s powerup definitely propels him far above Android 13’s current limits. Bojack wins.
