YMMV / Teen Titans S 3 E 2 X

• Fanfic Fuel: The mystery of Red X's identity aside, how did he manage to break into the Tower and steal the suit? How did he know about the suit? Is he even human? How much knowledge does he have of the Titans? How long ago did he steal it? His thieving self-interest aside, what is his overall end goal in life?
• Magnificent Bastard: Red X is a self-proclaimed thief who steals Robin's selfsame suit, then tracks down a Xenothium scanner even with the Titans hot on his trail. Cornered, X uses his knowledge of his surroundings and mastery of gadgetry, taking on the team one-by-one while he makes his way to the Xenothium Ore vault to recharge his suit and uses Robin as a decoy to slip by the security drone. Teaming up with Robin to stop the treacherous Professor Chang, X not only saves Robin but also gracefully accepts defeat when Robin reveals he stole X's utility belt. In "Revved Up", X races against Robin and many of his enemies, demonstrating his skill on a motorbike and when saved by Robin from an explosion repays the debt by dismantling all of the villainous racers in under a minute. Stylish and roguish yet noble, Red X cements himself as a memorable character that's neither a villain nor hero—just as he'd like.
• They Wasted a Perfectly Good Plot: As described in the Plot Hole in the recap page, the Titans never seem to be worried about their security being compromised considering how Red X managed to break in and steal the suit. If the Titans had a bit more common sense, their security being compromised could've led to a story arc where they're reluctant to trust others due to Red X getting the jump on them.
