"Arrow" season 5 welcomes new members to the Oliver Queen's team as Felicity says hello to a new boyfriend.

Prior to "Arrow" season 5, Oliver Queen (Stephen Amell) suffers from the loss of Black Canary (Katie Cassidy), who died, Diggle (David Ramsey) and Speedy (Willa Holland), who both left the team by the end of season 4. As a result, the head of the Arrow team recruits new members in the form of Artemis (Madison McLaughlin), Mister Terrific (Echo Kellum), and Wild Dog (Rick Gonzalez).

All three additions to the Arrow team can be seen in action in the new teaser released by CW on YouTube. Many avid fans pointed out that Artemis' costume resembles Black Canary's suit. This led many to believe that the new heroine will play a crucial role in the new season of "Arrow." Viewers are now speculating if the lady archer's character will evolve into someone who could create the much needed balance of the team.

The clip of the CW series also shows how Mister Terrific tries to triumph in the salmon ladder but fails to do so. It seems that Oliver is training the young team in preparation for more encounters with villains. It is not that Mister Terrific, also known as Curtis Holt, is not skilled at fighting. Perhaps Oliver needs his team in flawless form in case a battle ensues.

The "Arrow" season 5 trailer also shows Wild Dog briefly but merely a peek of the character. There is no significant clip of the character to find out what exactly the skills he has to contribute to the team.

Meanwhile, Felicity (Emily Bett Rickards) is set to have a new man in the new season, as reported by TV Line. Many Olicity fans find this piece of information unlikely, but the report reiterated that Oliver's ex will indeed introduce the new boyfriend early in this upcoming season.

To find out more about these new characters, watch "Arrow" season 5 pilot episode on Oct. 5.
