Transformers: Prime One Shall Rise Clip

Below is a clip from the first part of the three part season finale for Transformers: Prime. The last episode ended with an epic fight (really one of the best designed fights see between the two) with Megatron apparently winning as Dark Energon is ejected from a volcanic eruption. Various hints from previous episodes indicate this may be a prelude of the introduction of the Prime version of Unicron. (via TFW2005)
