I’ve been playing Jack X/Heihachi, with meter gems on Jack and power gems on Heihachi. I’m finding this to be a fantastic pairing for a number of reasons.
Every launchable chain (Jack has some range issues on his launcher) leads to 400+ damage before gems and meter. 500+ damage is pretty typical for 1 bar, and 600+ for 2 bars. Jack zones and builds meter, and once he has one bar, seismos and AA dps both turn into big damage and Heihachi mixing you up from point blank range.
One thing I’ve consistently looked for in terms of team synergy is the ability to kill a 1000 health character in 2 combos in reasonably attainable situation. This team has that in spades, especially when you consider the damage Jack does off a few pokes or seismos. A sequence of events I’ve been trying to make happen, especially in 2nd and 3rd rounds when I have meter to spare, is:
-Jack pokes you a few times as you’re approaching.
-You get hit by a seismo or dp that tags in Heihachi.
-Heihachi mixes you up and you die.
Some team specifics:
Because of the big horizontal hitbox on Heihachi’s j.hk, he can land a crossup j.hk after tagging in from Jack’s hp dp, and finish with a setup that deals with just about anything.
eg. :hp: dp, tag, j.:hk:, cl. :hp: xx :lp: dp, cl. :hk: into ambiguous crossups, +10 meaties, and standing overheads which can lead to a dead character with meter.
Off Heihachi’s hk Hell Axle, Jack gets
:hk: Hell Axle (tag first hit), j.:mp: (2 hits), cl. :hp: xx :hk: tackle.
