The Joker[src]

Titan is a compound created by Dr. Penelope Young and used by the Joker using research on Bane, specifically the drug used to give Bane his super-strength, Venom, and Poison Ivy's plants. Like Venom, Titan can turn any user of it into a Bane-like monster, but only a small amount is needed to trigger the transformation due to its potency, removing the need for a storage device. Though it comes at a heavy price for most; their bodies become horribly disfigured, and their rationality is lost and those infected attack anything unlike them(or sometimes they even attack each other). However, not everybody exposed to Titan necessarily showed symptoms. Notably, the Joker retains his "sanity" due to already being insane, as well as Bane due to his previous use of Venom, while Poison Ivy was not affected since she was only half-human. A similar compound, TN-1, had been developed by Bane during Batman's second year of activity.


Batman: Arkham Origins

A predecessor compond was introduced in this game. Bane had been trying to destroy Venom to eliminate his greatest weakness, but gravitated more to Project TN-1; he hoped to create a compond that will replace Venom's addictive prioperties and give a permenant transformation. However, the result was a muscule-bound brute with permenant memory damage. The full potentcy of the drug would take effect in 10 minutes, leaving a small window of vulnerability.

When Bane took the drug (since Batman had removed his activator switch for Venom), he grew into the giant he would be in future games. The drug also removed Bane's memory of Batman's true identity; the immediate sequel, shows that the physical transformation is temporary, but future games show that the user of TN-1 will regain their transformed state if they use a similar substance. 

Batman: Arkham Asylum

Titan was originally conceived by Dr. Young as a way for weaker patients to survive more strenuous treatments, and funded by the Joker under the alias Jack White to create an army of "a thousand Banes". Dr. Young's patient records implies that the Scarecrow assisted in the creation of the formula.

Venom was drained from Bane's body against his will to research Titan, plus the use of Poison Ivy's plants. The resulting compound bore little resemblance to the original Venom formula and was extremely potent. The effects of Titan typically grows the subject into a musclebound berserk superhuman, with increased strength, speed, and more resistance to melee attacks. The rapid transformation causes tears to the skin and bones to protrude out of the skin. It appears that all of Joker's Titan-enhanced henchmen were even more aggressive than they would normally be for a Blackgate convict, and behaved like raging beasts. Joker appears to not suffer this side effect, and even retains his speech and normal behaviors. Poison Ivy was also immune to Titan's side effects, most likely because she is not fully human anymore. Instead of undergoing a transformation into a giant killer plant, it is her plants that experience rapid growth, and their attacks becoming more powerful. Ivy's eyes turned bright glowing green and her chlorokinetic abilities were enhanced.

On interrogating Ivy, Batman discovers that special plant spores in Killer Croc's lair were key to creating an antidote. Batman described the process for the synthesis of the antidote as slow, and only yields small quantities. Although Batman had set his computer to synthesize more, the untimely growth of Ivy's Titan-enhanced plants invaded the Batcave and destroyed the computer, leaving Batman with very little antidote.

Fortunately, the effects of Titan was only temporary, and transformed inmates eventually returned to normal. The Joker, however, would suffer worse because an overdose from his dart gun caused residual Titan to be left in his bloodstream and reacted with other chemicals in his body.

Though all the Titan was thought to be destroyed, a post-credits scene revealed that at least one box was left floating in the water, and three alternate endings showed either Bane, Scarecrow, or Killer Croc grabbing the crate (based on the completion rate of the game).

After Arkham

During the comic book series bridging the gap between the two games, it's revealed that the Titan mixture has made its way into the Gotham underground. Crates of the compound floated into the docks and Two-Face bought it off of some gang bangers hoping for quick cash. Little late did he realize the mistake of having Brother-Sister team T&T (whose real names are Terry and Tracy Trask) take them down into a cellar.

Upon discovering what it was, they started using it and turned the cellar into a personal training ground. Because they used the drug in small controlled doses, they're able to retain control of themselves, and after slaughtering Two-Face's gang and nearly putting the man himself into a full body cast, T&T started making plans to take over the city.

However it's soon revealed that T&T were actually under the employment of Hugo Strange and under his instructions launched a coup against the city. Unfortunately for them, Batman arrived in time to save the city, but before he could trace them back to Hugo Strange they vaporized themselves via high explosives planted in their bodies, killing hundreds.

It's made clear that the purpose of the attack was to give Mayor Quincy Sharp the excuse he needed to create Arkham City. It seems that the Joker is planning to use the Titan again having had a doctor, which he promptly sent into an incinerator, isolate the Titan from his blood. In addition, the Joker had some of the Titan formula that was isolated from his blood injected into one of his henchmen, and then sent him after Bane.

After the henchman managed to place Bane at his mercy, however, the henchman started to suffer from cardiac arrest, resulting in Bane having to mercy kill the henchman. Due to this experience, Bane also vowed to destroy the source of all Titan by any means necessary.

Batman: Arkham City

After Bane's encounter with Joker's thug he launched a crusade against the Titan drug, realizing that he can't do it alone he signaled Batman with a flare and lured him into the abandoned Krank Co. Toy Factory in the flooded section of Arkham City. There he alerted Batman to the Titan in Arkham City (Depending on what point in the game the player chooses to meet Bane Batman will either find out from Bane or know of the Titan from a run in with the Penguin). According to Bane, the Joker was the one who arranged for the Titan crates to come into Arkham City.

Bane states that each of the remaining 12 Crates have been given a radio tracking device, Batman will destroy the six dotted around the south of Arkham City and Bane will take the northern six. Once Batman destroys his six he meets up with Bane and are ambushed by TYGER thugs. Batman and Bane quickly defeated them. Bane then reveals that his intent was to hoard the Titan to use for his own purposes.

Batman, however, anticipated Bane's betrayal. He was counting on Bane to hoard the containers and store them all in one place, so that they would be all that easier to destroy. Batman trapped Bane, then destroys the Titan canisters, finally ridding Gotham of the Titan.

Meanwhile, Joker used the isolated strain of Titan as a bargaining chip, having medical blood filled with the poison sent all over Gotham and injected into Batman.

The Titan, having been altered due to exposure to the other chemicals in Joker's bloodstream, would kill people in 24 hours. Batman had to rescue Mister Freeze from Penguin to make the cure. However, Freeze needed a specific enzyme to render the cure stable long enough to have any effect, which so happens exists in the blood of Ra's al Ghul due to his longevity. Batman infiltrated the League of Assassin's base, and forcefully took Ra's' blood.

Freeze was able to create the cure, but decided to hold on to it in exchange for his wife, Nora. He and Batman got into a fight over the cure, and while they were fighting, Harley Quinn stole the cure. The cure was in turn stolen from Harley by Talia al Ghul. The Joker killed her for it and the cure wound up in the hands of Clayface. Batman defeated Clayface and took the cure, he sipped it and cured himself before Joker stabbed him in the arm, causing Batman to drop the vial on the floor. Joker died as a result from Titan poisoning. Two weeks following the events of Arkham City, Harley Quinn injected a thug from her newly-formed gang with Titan to fight Robin when he infiltrated the Shipyard to rescue Batman. A Titan crate can also be seen as apart of the giant Joker monument, used to build his arm, implying more remnants of Titan remain.

Batman: Arkham Knight

The sole appearance of Titan in the game was found in a shipping crate containing Bane's former equipment, symbolic of how he was a changed man upon leaving Gotham.
