Parasite

Starfire is collecting food in space when she is struck by an alien creature. Back on Earth, she holds the Tamaranian holiday Feast Day, but the food scares the other Titans off, leaving her feeling dejected. A bulging infection develops on the side of her torso, a space parasite named Parry that communicates with Starfire through her mind. Everyone eventually warms up to the parasite except for Robin, who believes Starfire is out of her mind and that the parasite is out to destroy them. His efforts to convince everyone only hurts Starfire more, and Robin attempts to surgically remove it from her in her sleep. Parry then enters Robin's mind, where Robin realizes that he misunderstood both Parry and Starfire. Parry then decides to separate from Starfire and depart from the Titans. As they bid their goodbyes, Parry suddenly mutates into a giant spider alien (the Cironielian Chrysalis Eater from the original series) and warps them all across space. Seeing that he was right all along, Robin rubs it in everyone's face before Parry crushes them with her claws.
