Robin attempted to save Dava, but since he was still under the effects of the Aramilla plant, he did not realize his own speed and strength, and accidentally killed the normally unbeatable Shiva.

At that point, King Snake arrived with more armed Kransa-Volvian troops, seeking to avenge his earlier losses at Robin's hands.
