So, one by one,
AP- Kensiro when using his technique (2.18 teratons), equal otherwise (~600 Gigatons each) Speed- Vayla amps pretty well and will keep up rather well.
So, a few things to note:
Pressure points may be difficult, given her hand-to-hand mastery and slightly unorthodox biology, though some of those effects are rather potent, namely explosions.
The Flames of The Consortium are likely dispel-able by Kenshiro, though if he's barraged, he may find himself in danger.
Intangibility doesn't mean anything with her non-physical interaction, and erasure doesn't scratch her, and she's more than capable in hand-to-hand.
Kenshiro can do massive damage with various techniques such as explosions, though, and with the AP advantage, he can certainly hold his own.
So, the battle starts.
Vayla leads with splitting some timeline hairs and gathering some quick information about the opponent, while taking key abilities herself.
She will then play a mid-ranged game, using speed and time manipulation to weave outside of his range with skill and precision.
Overall, the question is, does Kenshiro have a way to actually pin her and her clones down through her massive wall of versatility and capabilities?
