Ryoko's Universe+ level, so around the level of the Hakaishin, Jiren and the Angels. With the scenario you provided, Goku would probably reach, if not surpass, Zen-Oh tier, so he stomps.
Future Super #17 runs the Cell Arc Gauntlet
- Two versions of Future #17 fuse via the same methods as in GT.
- Energy absorbing is allowed and his weak point applies.
- No intel for either side.
- If Super #17 solos, have him run a Boo Arc Gauntlet.
Edit: Likely GT Goku due to the amount of training time he had.
Super #17 likely solos the Cell Ar Gauntlet, since Super 17 in GT was capable of absorbing energy from even SSJ4 Goku and could still absorb much more. I can see Super #17 win against even SSJ2 Gohan that way.
He'd probably lose against Good Boo, though.
Zen 21 VS Kami Tenchi universe
- 21 has copied Boo's absorption, then absorbed Zuno to get his nigh omniscience in order to find a plan to absorb everyone.
- Afterwards, she used the Super Dragon Balls to "fuse" with almost everyone in the DBVerse, in all timelines, gaining all their power, abilities and knowledge combined. The fusion is forceful, with her being the only one in control, and with the same boost as Potara fusion...and this is permanent. The only ones spared are the inhabitants of Universe 1 and the angels.
- As the new ruler of the universe thanks to having Zeno's power, she has trained for 100 of earthling years in RoSaT* with all angels (including Great Priest), unlocking Ultra Instinct. Aware that she has the greatest potential in the DBVerse (now much greater thanks to her "fusion") due to Zuno's knowledge, she knows that she will never be surpassed by anyone in the DBVerse after such a training.
*: 100 earthling years is equivalent to 13+ millions in RoSaT.
