Nexus' eyes widened as Ren disappeared into the smoke. "Void.." He said under his breath, taken aback by his ability. Nexus rose his blade up as soon as he was able, barely able to divert Ren's larger blade just over his shoulder. His armor released a pulse of energy to prevent penetration or rending of the exterior, as well as pushing Ren's attempt to grapple him away, allowing him to roll to his side and regain his balance a moment later. Nexus stood and backed away, sizing up Ren curiously. "Enough of your incessant ramblings, fool! Where did you learn to harness the void!?" Nexus interrogated, raising his flaming sword to defend once again if need be. His face was covered moments after speaking with a sharp helmet that allowed enough room for peripheral vision with its wide angles eye slot.
