Tenkai's overhand cross could only go so far, and it would matter even less as Heita moved himself to the right. Tenkai's fist wouldn't even graze him at this point. With Heita's body weaving to the right, it would seem as if Tenkai's left side would be perfectly exposed for Heita's intended hook.
Or at least that's how it seemed at first.
With Tenkai's left side leading, his left arm would end up being much closer to Heita's body than Heita's glowing right arm would be to Tenkai's left side. With his previously parrying left arm pulled back to his side as a result of his following right overhand cross, chambering his fist would take hardly any time at all. From this point it would look as if Tenkai was in a perfect position to follow up his cross with a straight punch, if not for the fact that the monk had strangely relaxed his fist into an open palm.
As Heita whipped back from the lean, Tenkai drove his left arm forward, rotating his palm upright as the burning red glow from Heita's incoming hook would be accompanied by the contrasting light blue of Tenkai's spiritual power...
天破剛掌波
"Tenha Goushou Ha!"
(Heaven Breaking Rigid Palm Wave)
With an added step of his forward left foot, Tenkai's palm strike would close the short gap between Heita and Tenkai in a straight line as the hook came around. The bounce-back from Heita's weave and the motion from his hook would serve to bring him into Tenkai's strike, using the Colonel's own force against him. Tenkai's palm would drive into the center of Heita's mass towards his solar plexus, cutting the hook off half way by stepping into the strike.
Unlike Tenkai's earlier attack, there wouldn't be any internal damage as a result from the impact. Instead, Tenkai released his spiritual pressure in a powerful linear shockwave for increased external force that would crash against Heita's body and ripple across his torso. The Tenha Goushou Ha was as much a projectile attack as it was a palm strike, and the shockwave would travel with him, knocking him back much further than the Tekkouha Gankai Geki had.
Heita would feel as if he had been struck with a palm as wide as his entire torso, though the solid center of mass driven by Tenkai's actual palm heel would be aimed towards the bundle of nerves in his solar plexus for a powerful shock to the Colonel's system. At the very least, with Heita presumably being human or at least not of some corrupted influence, the flame-like blue spirit energy washing over him would not end up causing additional burning damage.
