Zion stood not incredibly far from the action between Mori and Aya. Words being exchanged falling on unfocused ears as the Lion stared somewhat blankly at the fire-villain. You see. Zion was about to head for the lazer-shooter. Yet froze when eyes landed at the palms of the fire-quirk user. Memories and visions of prior times, growing up in Africa, flashed through the lion's mind as he momentarily lost track of where he was. Shaking his head, regaining his bearings, Zion turns to narrow attention onto the dust cloud dissipating around Aya and Mori. Hopefully this didn't damage his allies too badly. Yet with Mori's likely high-level hearing. Zion had a feeling this could pack a punch for the wolf-kid.
Goal of this action was to, possibly, phase Mori long enough to give Aya the chance needed to take him down using her quirk. A bonus would be if the wannabe hero didn't manage to land an attack because of this idea. Deeply inhaling, staring into the sky, Zion performs a roar as loud as he could. Echoing through the area the loud noise boomed. Far higher in volume than any ordinarly animal could muster, at the stake of his voice. A grunt followed the Lion's action as vocal chords were heavily strained. A hand even going against his throat after performing the act.
