The CW has released the trailer and preview images for the Arrow Season 5 finale "Lian Yu" which airs May 24.
The battle between Oliver 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.
Arrow airs Wednesdays at 8pm ET on The CW starring Stephen Amell and moves to a new night and time for Season 6.
