So from what I understand, VT II for Akuma lets you cancel specials in to EX moves and consumes your V Timer for EX rather than your actual meter.
So knowing this you could probably change a lot of existing combos to get a higher damage outcome. Since we don’t really know how much of the V Timer is consumed per EX move, we’re going to ignore how much we consume.
Here’s an advanced combo I thought up
JIP > St. MK xxx H. FB xxx VT > H. FB xxx EX FB > H. DP xxx EX DP xxx CA > H. DP xxx EX DP
(At the end there is just assuming EX DP launches them high enough for you to follow up after CA with another DP.)
Now here’s a simple BnB with VT II in it
JIP > Cr. HP xxx VT > St. Mk xxx L. Tatsu > H. Tatsu xxx EX Tatsu (in air)
This is what I think was shown in the screenshot for his VT II. Essentially it’s the same combo but you’re cancelling H. Tatsu near the end of the animation with mid air EX Tatsu to finish the combo.
Now here’s a corner combo
() = Target Combo
JIP > Cr. HP xxx VT > (St. HK > St. HK) > St. MK > M. Tatsu xxx EX Tatsu > H. DP xxx EX DP
These are just a few combos I thought of, go ahead and share your own. None of these are guaranteed to work when the game comes out, these are only ideas.
