I may try to write up more with Kano but you'll get the idea from this I'm sure:
Main BnB 7f Punish:
12xshriek, dash, f4xfloat(f), j12(Bkano)3xtele(d), 4xpush for 323 damage, no bar, 1 Kameo.
And damage is not Kano's big appeal. Kano let's you combo off of lift in the corner, sweep, and some other things meterlessly that you'd otherwise not be able to, but his big help is making teleport pseudo safe and a meterless launcher, along with enforcing Oki and approaches with Kano Ball. Knives can also help you approach, and if you're full screen, knives plus tricky ghoul low hands is something they have to hold.
I see a lot of potential with Kano/Ermac, but I've been dealing with Wisdom tooth junk and DRs and Surgery and all that so I haven't really had time to put all my thoughts down yet.
