Liv takes personality traits of Ra's al Ghul.Facebook/iZombie, Arrow

Stephen Amell, who plays Oliver Queen in popular supernatural series "Arrow", recently hinted at the possibilities of a crossover between all the DC television shows.

While attending Wizard World Philadelphia Comic Con, the actor said that DC characters in television shows do not have any limitations. "There is an opportunity for inter connectivity with any DC television show that exists," he added.

Citing NBC series "Constantine" as an example, the 34-year-old revealed that he had discussions with DC to appear in the show as a guest star and not with any cable network, according to Comicbook.

However, there is one DC spin-off that can never have a crossover with "The Flash", "Arrow" or "The Legends of Tomorrow" and it is "iZombie". But what if the comic book publisher does decide to introduce Olivia "Liv" Moore (Rose McIver) to Team Arrow?

Since Ra's al Ghul (Matthew Nable) is speculated to die in "Arrow" season 3 finale titled "My Name is Oliver Queen", the zombie could get a chance to eat the brain of League of Assassins leader. When the former cardiac surgeon takes personality traits of the villian, she decides to meet the Green Arrow and the summary of the episode could be as below:

On her way to Starling city, the brain eater meets Ray Palmer aka The Atom (Brandon Routh), who is in search for a romantic partner after his break up with Felicity Smoak (Emily Bett Rickards). As the new superhero gradually falls for the zombie, Barry Allen aka Flash (Grant Gustin) enters the scene and warns him about the danger.

While the two struggle to conquer Liv, Green Arrow reaches out to help her and defeats the brain eater. When McIver's character prepares to leave Starling city, Queen offers her a place in Team Arrow, but she denies it.

However, the above scenario is purely a speculation and a crossover between the two series is the least possible thing to happen in DC world.

So fans of supernatural characters can tune in to The CW this Wednesday, 13 May, at 8pm to find out more about Nable character in "Arrow" season 3 finale titled "My Name is Oliver Queen", which will be live streamed  here.
