"Arrow" Season 4 will feature Nyssa Al' Ghul, the daughter of Ra's al Ghul. It is most likely that she will lead the League of Assassins.

According to YIBADA, there might be a death of one of the main characters in the upcoming season.

During last season's finale, the viewers saw Felicity Smoak, played by Emily Bett Rickards, gunned down in an ambushed by The Ghost. It was just right after Oliver Queen, played by Stephen Amell, proposed to her in front of everyone during a Mayoral Speech in Star City.

In what we see in the next season's trailer, Felicity will fight for her life, while Oliver grieves over a tombstone of someone he knows. We weren't able to see who that person is. Filled with guilt because he has put all the blame to himself, he promises to kill Damien Darhk (Neil McDonough) for what he has done. He is out to avenge the death of his friend.

The 34-year-old Amell also explained during the "Heroes & Villain Fan Fest" event that he has no idea who is in the grave. Amell is either just teasing the fans in the venue or he just doesn't want to spill the secret at all, according to Melty.

Arrow fans will have something to look forward to in 2016. This season will be packed with action and may also include a bit of drama as well.

"Arrow" Season 4 returns January 20, 2016, only on the CW Network.
