About a week and a half later, Gordon called the Titans to the police station and explained that an informant, Catgirl, had revealed that Two-Face was up to something. Gordon later explained to a returned Batman that Walker had escaped Arkham with Bane and pulled strings to have Freeze released, so he could help.

The man then ordered her to rob a bank as Blackfire. She ran into Superboy and pushed him aside before his budding x-ray vision caused him to see her green skeleton, a side-effect of her gaining her powers. She was later ordered by the "bad man" to kill Superboy. She managed to wind Superboy with a punch, but she was held up on a piece of earth by Terra and cried to be let down. After that, she gave up, and Superboy took her to the Kent Farm to be taken care of, allowing Tina to realize that Superboy was Conner Kent. A couple of months later, Tina was four years old again, and when the Titans arrived at the Kent Farm to relax, Tina played with Superboy's new dog, Krypto.
Krypto- A dog that was genetically altered to have the same powers of Superman and Superboy. He eventually met Superboy after he escaped and played fetch with him and showed that he had super speed, super strength, and he could fly. Krypto then licked Superboy's face. He later flew to Titan Towers with him. Upon meeting the other Titans, Krypto immediately licked Raven's face, despite her protests. Krypto then caused some trouble when he ate Blackfire's favorite pair of boots and drooled on the T-Car. He then got reprimanded by Starfire when he drank out of the toilet. He more than proved he could earn his keep when he fought a bank robber who had beaten the other Titans and tore off his mechanical arm, which had the money, and pulled apart the rest of the suit before pulling the pilot out. Krypto was then congratulated by the Titans, and he licked Raven again. He even managed to win over Cyborg and Blackfire and became a Titan. When the Titans relaxed at the Kent Farm, Krypto played with Tina. Krypto later covered his eyes while he watched a video about antelopes mating and blushed. He then went with the Titans to stop a bank-robber named Exotica. He was then targetted by a controlled Cyborg, but he pinned him down. After that, he was revealed to have recently pooped in the shoes Blackfire was wearing at that moment. He later went to sleep between a de-aged Superboy and Raven, and they petted him as they napped. Later, he comforted Blackfire when she was feeling alone and listened to how Blackfire had believed her time with the Titans has changed her. Krypto then jumps on a depressed Raven and licks her until she giggles. At Gotham, Krypto chased Mel around excitedly before he was calmed down by Conner. Shortly after that, he waited with Mel for the Titans to return from Ra's Al Ghul's challenge which they did. After that, Krypto licked everyone. After returning home, Krypto went on a walk with Beast Boy and dragged him all over the city. Later, he played fetch with Terra and brought her ball back a few seconds after she threw it. She then barked when Starfire offered a treat and gave it to him. After that, Krypto was licked on the cheek by Mel, which set off his heat vision and destroyed the fridge. When Cyborg called him up, Krypto whimpered. Once he assured Cyborg he didn't mean it, he was forgiven. On Tamaran, Krypto played with several Zarnics.

Starfire then tried to kick him down to give Superboy time to recover, but she only ended up hurting herself. His Kryptonite heart's radiation was then blocked by Raven, so it couldn't supply him with power, or weaken Superboy. He was then punched into the sea.
Clayface - Somehow recovering from his fight with the Justice League, Clayface was recruited by Zod to attack a prison in Jump City. He then ran into the Titans and fought them.
