The final battle between Oliver and Damien Darhk will be featured in the finale episode of “Arrow” Season 4. A preview video of the episode shows the strategy the hero uses to take on his powerful enemy.

[Spoiler alert]

The darkness inside Oliver (Stephen Amell) prevents him from effectively fighting against the magic of Darhk (Neal McDonough). According to the official synopsis of the finale episode, Oliver will team up with a “surprising force” to take on the villain. The preview video of the episode shows, at least in part, the strategy the hero will use.

Oliver is a natural leader and has great influence on the people of Star City. He will use his charisma to implore the people of the city to fight Darhk alongside him. The preview video shows that the people of the city will join the fight in droves.

Apart from defeating Darhk the heroes will also have to stop the world from nuclear annihilation in “Arrow” Season 4 finale. Felicity (Emily Bett Rickards) managed to stop most of the nuclear missiles in a previous episode, but could not stop one missile. Although she prevented the deaths of millions of people, she felt guilty for being the cause of the deaths of thousands.

Executive Producer Wendy Mericle shares her insights in another video released by The CW Television Network. The video gives the viewers an inside look at the episode titled “Lost in the Flood.”

Mericle pointed out that the deaths of about 20,000 people made Darhk immensely powerful. She said that the villain is now a “superpower” and the heroes have a “big, big battle on their hands if they’re going to defeat him.”

The preview video of “Arrow” Season 4 finale shows Darhk capable of hurting multiple people at the same time. The video also shows the headquarters of the superheroes under attack.
