With the fifth season of Arrow gearing up for what is sure to be an epic season finale, it's clear that Oliver Queen is going to need all the help he can get when it comes to taking on Prometheus. The hooded menace is intent on destroying Oliver at all costs, and has taken great pleasure in besting him.

The Emerald Archer has been both physically and mentally beaten by the unstoppable Big Bad, and all hell is set to break loose when the season finale heads back to where it all began for the show: Lian Yu.

With the finale looming, The CW has released the synopsis for the episode — which is appropriately tited "Lian Yu" — and it teases some pretty major action, as well as some incredibly exciting returns. Check it out below:

DEATHSTROKE, NYSSA AL GHUL, MERLYN AND DIGGER HARKNESS JOIN OLVER’S BATTLE AGAINST PROMETHEUS — The battle between Oliver (Stephen Amell) and Adrian Chase (Josh Segarra) culminates in a final epic battle on Lian Yu. After recent events, Oliver decides to recruit a group of unlikely allies — Slade (guest star Manu Bennett), Nyssa (guest star Katrina Law), Merlyn (John Barrowman) and Digger Harkness (guest star Nick E. Tarabay) — to defeat Chase. However, Chase has his own army – Black Siren (guest star Katie Cassidy), Evelyn Sharp (guest star Madison McLaughlin) and Talia al Ghul (guest star Lexa Doig) — and the forces collide in an explosive season finale.

Boomerang Is Back

One of the most interesting things about the synopsis is that it teases the return of Captain Boomerang. The character initially appeared back in Arrow's third season before he was taken down by the Arrow and in the first of the CW's annual crossovers. After this, he was imprisoned by Oliver in the same Lian Yu prison as Slade Wilson.

Fans had been hoping that Harkness would eventually return to the show, but that never happened — the most likely reason being the character's big screen debut in 2016's . But now, his impending return could indeed bring with it the opportunity for more appearances in Season 6. Moreover, his presence is undoubtedly a more than welcome addition to an already star-studded season finale.

All Star Team-Up

Captain Boomerang isn't the only character returning. According to the synopsis, he will join Deathstroke, Nyssa Al Guhl and Merlyn as they aid the Green Arrow in his fight against Prometheus. But the villainous archer won't be coming alone either, as he will have Black Siren, Artemis and Talia Al Guhl in his corner.

After a tension-filled season, I couldn't think of a better ending to this story. Furthermore, as Arrow prepares to bid farewell to Lian Yu once and for all, it will surely be amazing to see our favorite Team Arrow members and returning regulars Katie Cassidy, Manu Bennett, John Barrowman and Katrina Law wage an all out war on the uncharted island.

But the question is — aside from Black Siren, confirmed to return next season — who will be left standing when the dust settles?
