It is being speculated that Oliver Queen (Stephen Amell) will be taking on the iconic Batman super villain Harley Quinn in episode 16, season 2 of Arrow.

Stephen Amell Confirms Show's Third Season on Twitter?  

After rumors DC comic character Quinn featuring in the next episode, Suicide Squad, of Arrow started doing the rounds, blogs have started wondering if Oliver will be up to the task of combatting her evil highness.

In the 30-second preview for the episode, fans were introduced to the dangerous team.

A team member who is not clearly visible to us is seen as part of the team in the teaser and online blogs like Screen Rush are suggesting it might be none other than DC's iconic villain Quinn.

Behind the prison cell bars, a blonde whose back is faced to the camera, wearing her hair in loosely-tied pigtails, is seen, and she is being picked as being one of the usual suspects. Quinn has been included in DC comics Suicide Squad as well and Arrow has featured Batman characters in the past.

The clip essentially amps up the fear factor.

"We've been tracking death stroke, find him," one of the Arrow team members is heard saying. The threat is asserted as one of the other members -- "you can't go there by yourself, it's suicide" -- warns about heading into the squad cell.

The suicidal gang is shown dressed in yellow jump suits and the leader of the pack, who wears a black eye patch, is seen welcoming the Arrow team members.

The synopsis of the episode, called Suicide Squad, suggests the Slade Oliver feud will be dragged on for a while. Oliver will have to prepare to combat his former friend who has sworn to destroy Oliver and his family.

The synopsis also reveals that Diggle will be helping Amanda and A.R.G.U.S. to take on a warlord from Afghanistan, but he will end up finding himself in a sticky situation.

Suicide Squad will air on March 19 at 8 p.m. on the CW.
