Ahead of 100th episode, "Arrow" Season 5 episode 7 will see the arrival of Vigilante (Josh Segarra) in the Star City on Nov. 16, Wednesday. The new character is keen in protecting the city in his own way, which places the team Arrow in much confusion.

Vigilante is a mysterious crimefighter, who is either an ally or an adversary. Green Arrow/ Mayor Oliver Queen (Stephen Amell) and his group will be divided, whether they will help him or stop him from protecting the city when the "Arrow" Season 5 episode 7 returns.

"When you finally meet Vigilante, it's a pretty exciting time for Chase and for the Vigilante," Segarra told  TVLine. "Chase starts getting involved a little bit more into the rest of the world."

Team Arrow will be down only to just Queen/ Arrow and Felicity Smoak (Emily Bett Rickards) while John Diggle/ Spartan (David Ramsey) returns to the military and Thea (Willa Holland) is still resolute as Speedy. In a flashback, Queen will be seen having a conversation with Konstantin Kovar (Dolph Lundgren).

D.A. Adrian Chase assumed the name Vigilante after his family was murdered in the DC canon. Another new character Talia al Ghul (Lexa Dolg) was previously reported to appear in flashbacks in the new episode.

 "Arrow" 100th episode is slated to be seen in the coming weeks. It will see the biggest crossover of The CW series, including "Arrow," "The Flash," "Supergirl," and "Legends of Tomorrow."

Following "Arrow" Season 5 episode 7, viewers will be looking forward to the happenings in the major crossover of The CW shows. In an interview with Screen TV, executive producer Wendy Mericle said that  the 100th episode will be a time to celebrate and pay tribute to Season 1 and to the Queen family.

There are rumors that "Arrow" cast member Susanna Thompson will be returning in the 100th episode as Moira Queen. The details of her speculated comeback are not yet known or in which episode she will appear, but it is expected that her return will be an emotional moment for her children Arrow and Thea. Mericle confirmed that there will be iconic moments in the momentous episode.
