Thunderclap was ever in the pursuit of perfection in his field: speed and power. As a result, his explosive capacity was dominating. In the process, however, he had to give up defense and energy conservation. Landing an attack or gaining the upper-hand was followed by the rage of a thunderstorm.
Thor, his weapon locked and his movement constrained, was certainly caught in a disadvantageous position. With years of combat experience at play, Thunderclap was certain Thor had no recourse, no means of escape.
But just as Thor’s defeat seemed inevitable, a gentle blue light appeared between them to ward off the blow. The shield of blue energy undulated as Thunderclap’s strike crashed against it like a tidal wave. The electric power was harmlessly diffused in to the atmosphere around them, and brought the blue-black mecha to a shuddering halt.
