While the mid-season finale just aired last night, new Arrow Season 2 spoilers have circulated online.

The two-parter mid-season finale concluded last night (Three Ghosts and The Scientists). The first half of the season gives us a glimpse on what's going to happen this season. CW also gave us the first major super-powered villain in the series.

But, it seems like the hit CW TV series is just starting to heat things up!

The second half of Arrow Season 2 will be back next year on January 15, 2013. When it returns, the hit TV series will get more exciting with another villain coming to Starling City!

His name? William Tockman, or popularly known as the "Clock King."

"Clock King" is not that popular in the DC Comics list of villain characters. However, he has made several appearances on both DC Comics' Green Arrow and Batman as well as the Justine League.

Quick background on the "Clock King" based on The Unofficial Guide to the DC Universe:

"William Tockman was told by a doctor that he only had six months to live. Becoming obsessed with the remaining time he had, he decided that if he was going to die, his mentally impaired sister must remain safe. He studied the timing of a bank during all of his shifts, and then donned a clock-themed costume and attempted to rob the bank. Unfortunately, Tockman tripped a silent alarm signalling Green Arrow I. He was incarcerated and his sister was placed in a state-institution where she soon died. In prison, the 'Clock King', as the media called him, realised that he wasn't going to die - his doctors had accidentally switched his files with another. Angered over the death of his sister, Tockman attacked Green Arrow for revenge, but was incarcerated again. When the Clock King's prison time was over, Tockman joined the Injustice League and fought the JLI. The group temporarily reformed, forming the Justice League Antarctica, but was short lived. After turning to a life of crime, including a brief spell as the leader of a group called the Clockwatchers, the Clock King and some of his buddies signed up for the Suicide Squad, which was offering parole. The Clock King died on the first mission."

The ever-punctual villain will be portrayed by Prison Break's Robert Knepper, TV Line reported.

Further reports state that Knepper will be appearing on a single episode for now, making him a guest-star on the CW series.

There has been no confirmation yet if Knepper will become a regular villain on the series. But , knowing how Knepper brilliantly portrayed his villain role in Prison Break, there's probably a good chance he'll become a popular villain in the hit CW Arrow Season 2 series.
