It's Raven's birthday, but she is far from wanting to celebrate. But before Robin can learn why, the Titans receive a distress call and go to check it out. When they get there, they are greeted by none other than Slade, back from the dead. But Slade seems to have new powers along with a strange red mark on his head and he has a message for Raven that he is going to deliver, no matter what.

Cyborg is mysteriously thrown into the distant past and lands in the middle of a barbarian village that needs his help. But with the nearest charging station 5,000 years in the future, Cy has no way to recharge, and his power supply is dwindling.

Beast Boy has only one real dream in life -- to someday, somehow own a Moped. And when Robin won't buy him one and Cyborg won't build him one, Beast Boy has only one way to make his dream come true he has to get a job.

A brave hero from outer space called Val-Yor comes to Earth, and asks for the Titans help in defeating an otherworldly menace known as The Locrix. But according to Val-Yor, Starfire may be the real problem...

Ever since Slade's return, the Titans have been searching high and low for answers, including looking for theories as to the 'S' mark on his forehead. However, Raven knows why he's back, and the Titans are about to discover the truth themselves after Slade launches another attack.

An exciting battle on a distant space station ends with a tremendous explosion that blows the T-Ship apart -- and sends the Titans flying off in five different directions to crashland on a strange alien world.

Wishing to get the most he can out of his time, Cyborg installs a special Max-7 chip into his head which throws him into overdrive, allowing him to do a lot of things, very fast. But when the self-copying Billy Numerous starts stealing everything in town, even the Max-7 may not be enough to stop him.

The strange Mother Mae-Eye has taken the Titans on as her children and turned the tower into a massive gingerbread house. But even below her initial weirdness, she just keeps getting weirder.

The day has finally come. Raven is destined to end the world on this day. Trigon will come by sunset. But not if the Titans have anything to say about it. They place Raven in a safe room while they take on an army of flame creatures and Slade who is determind to take Raven to the Trigon. But Raven knows the horrible truth. No matter what the Titans do, there is no escaping her destiny.

Robin, Starfire, Cyborg, and Beast Boy awake to a nightmare. Trigon has risen and he has ended the world. Every building is destroyed, and all life has been turned to stone. Due to one last gift of Raven's, the Titans have survived. Now, they must find a way to get Raven back, maybe she knows of a way to stop Trigon. But to do this, the Titans will have to accept help from their old enemy - Slade.

The stars are aligned. The sun is in eclipse. All of Slade's labors are about to reach fruition -- and the Titans are about to face their greatest challenge ever. But is there really any hope of preventing the end of the world?
