The fight with Skanda wasn't that straight-forward either. Both used their Shakti weapons and at first Takki managed to land a severe blow on Skanda; so much so that Shiva's son was rendered unconscious for a while. He got back up and hit Taraka but the asura got back up again. Finally Skanda remembered his parents, offered obeisance to them and hit Taraka with one final fatal blow.
So far DkDM has usually failed to live up to their grand promos and audience expectations when it comes to these big moments. What do you think? What should we expect?
Note: I suspect we won't see Takki fighting Vishnu or at least we won't see it the way I described above for obvious reasons. Also in the texts Shiva instructed Veerabhadra not to kill Taraka because the boon was about Skanda killing him. I think Veerabhadra won't be brought back on the show.
