This seems to be quite close at a glance, but it doesn't seem like much of Hades' arsenal can really do much to Tenshi. Soul absorption counters power null, dimensional travel counters BFR, and passive, multi-layered probability and fatehax means Hades will struggle to even hit Tenshi, while every possible outcome is tilted in Tenshi's favor. As for wincons, Tenshi can either do this the good old fashioned way of beating him to death, seal his abilities (which, tbf, I don't know if the mechanics being slightly different is enough to bypass Hades' power null resistance), or simply absorb his soul, mind, and so on (these hax are very heavily layered, so I don't believe Hades' resistances to any subset of Spirit manipulation will be enough).
Granted, that's not to say Hades is completely ******, as his sleep manipulation is a very good wincon, and things like life absorption, invisibility, and perception manipulation will make him incredibly difficult to attack safely. That being said, I don't think this works around Spirit manipulation given Tenshi can use it to cover a multiversal range (which also means Hades can't avoid it by dimension hopping), so it's not like she needs to see or directly attack him in order to harm him.
There is also the issue of the AP/durability gap; I don't know what Hades scales to, but Tenshi is massively above Doremy's several dozen times uni dream creation, and she was able to shake the Heavens just by preparing to fight. Her durability is massively above this as well, since she can no-sell attacks from characters comparable to her in AP (and eat more celestial peaches to stack that already absurd amp). Whatever the gap may be, though, it seems like Hades has multiple ways to close that gap, whether that be through his own stat amping or reducing Tenshi's stats. The main question, then, is whether or not Hades can last long enough to gain the upper hand in that regard.
Tenshi takes this high diff, I think, though I'll wait for further input from GoW supporters.
