So I've been rereading some old slaine comics and designed a few mythic feats around them, what do you think, too weak? Too much?
You vault above a charging opponent with amazing grace, only to land and strike from behind. As an immediate action, when an opponent charges you in combat you may expend 1 mythic power to leap over the opponents head, landing behind them. You may then make a single melee attack treating your opponent as flatfooted and flanked. Your opponent resolves the effects of its charge after this attack.
Prerequisite : Titans Rage
When you use your titans rage ability your body literally spews forth the bile and fury you feel. You begin to bleed the black blood of the earth from every orifice and exude and palpable aura of dread. While under the effect of titans rage you may use intimidate to demoralise all foes you threaten as a free action once per round. This attempt automatically succeeds against non-mythic foes.
He didn't think it too much
You thrive upon the chaos of combat, driven by press of bodies and the dangers of overwhelming odds. You gain a +1 bonus to attack and damage rolls for every opponent that threatens you in melee combat up to a maximum equal to your mythic tier.
