Teen Titans S03 E02 X

"When there's trouble, you know who to call."

There's a new thief in town - Robin's former evil alter ego, Red X. Robin feels that this is all his fault, and must stop X from getting a dangerous powerful chemical known as synovium that will power him up. Robin stops at nothing to catch his former evil alter ego - but it turns out that there may be a even bigger villianious plot in the mists.
