9-C: Makes it pretty far due to the tier being full of haxless martial artists, assassins, soldiers, etc. who only have Peak Human speed, but he doesn't gain very many powers from them either for the same reason. There's also a rather significant possibility that
Johan Liebert will manage to get into CH's head and eventually talk him/her into killing themselves, though I can see a scenario where that ends up not working.
9-B: Makes it midway at best due to Supersonic speeds and low-tier hax being a norm at this level. Guarantee you he/she doesn't even make it past
Kirei Kotomine or
Roland Deschai, since they have extremely reliable ways to oneshot while simultaneously outclassing the Human in speed. (And firearms skill in Roland's case, as most of his marksmanship feats are literally humanly impossible)
9-A: Again, Roland exists here, so CH isn't going to make it very far at all. The Human is ****** if he/she goes up against
Daredevil or
Midnighter, and even if those two lose (which the latter most definitely won't), he/she will then at some point have to contend with guys like
Caleb,
Raziel,
John Constantine and
Crowley, all of whom utterly destroy CH even with that half-day of prep time. And really, before even making it to those four, he/she will be faced with
Conker the Squirrel, who will probably outlast him/her just on the virtue of canonically having infinite lives.
