I hate I'm getting any hopes for Black. This is a DC win. But still... Black has shocking number of good points if Infinite Zamasu is used.
- Again, Black AP stomps, esp. since with Wally they still compared his physicals to Infinite Mass Punch
- Time Ring shenanigans
- DB Final Form rule means Merged/Infinite Zamasu will be used and can't be said "blitzes before he merges"
- Merged Zamasu is a blessing, as Kaioshin half gives him ability to teleport anywhere, like U7 Shin teleported to Zeno presumably outside of U7, thus Merged Zamasu escapes BFRs
- Kaioshin's can live for millions of years, so he actually should resists age manipulation much better, making it far riskier for RF to attack Zamasu
- Infinite Zamasu is space, hard if not impossible to hit him directly
- I-Zamasu spreading means eventually he can tag RF, because he can't outrun space itself within normal universe...
- ...and somehow due to I-Zamasu leaking to primary timeline means he should be able to leak into where ever RF will time travel to
- The Ultimate Shenanigans that will happen if Black/Zamasu wins, is that I think RF might just be still stronger, sure RF's physicals might suck vs him, but DC Speedster being able to destroy DC Multiverse might just surpass Universe Multipliers versus DBZ, but unbelievably if this is only conventional destruction, that might not cut it if its implied you need super strong erasure to beat I-Zamasu
But like, I then remembered Bleed scaling, which RF might not scale to, but either way I'm expecting them accepting RF being able to destroy I-Zamasu via running.
...But technically I-Zamasu has a lot going for it versus a god damn DC Speedster. In some way its impressive.
