Teen Titans Go! Many DC characters make cameo appearances and are referenced in the background. The original principal voice cast returns to reprise their respective roles. After using a repellent to temporarily prevent the Powerpuff Girls from moving, Mojo Jojo uses a teleportation device to teleport himself into Jump City, in the Titans' tower, then the girls follow him into the same place where he appeared, only to run into Robin, Starfire, and Raven.
Spoiled, bossy, and bratty, Kitten is perhaps the only person her father ever knuckles under. Kitty is the typical spoiled teenage girl; all she wants is to be adored and lavished with attention. She will do anything to be better than everyone else, including making them jealous. She succeeded in that goal by bringing Robin to her Junior Prom. Kitty is also very acquisitive and materialistic, finding Fang's array of jewelry a true sign of his love for her. She is also a sore loser eager for revenge on any who have 'wronged' her. After her brief breakup with Fang, she commanded her father to convince Robin to go on a date with Kitten.
The leader of the group, Robin is the sole Titan without superpowers, bar the ability to transform others and relies mainly on his arsenal of weapons and tools in combat. His weapons of preference are his Birdarangs , grapple guns and multi-purpose metallic bo staff , which he is, at one point, deluded into believing is his best friend. As in the previous series, Robin is fiercely disciplined, highly serious and hopelessly smitten with Starfire. Robin's role as leader is modestly parodied throughout the series, as he seems almost incapable of taking direction from others, easing his strict mannerisms with his teammates, or accepting any task lesser than the most important or dangerous one. He is also disturbingly emotionally unstable, often being rude, arrogant, spoiled, self-centred, and impulsive towards his teammates or simply crazy. His original comic book likeness is also featured briefly in "Books", and he is seen in his original comics outfit in a flashback in "Baby Hands". An orange-skinned, green-eyed alien princess, Starfire real Tamaranian name Koriand'r is formidable for her superhuman strength, faster-than-light flight, and ability to emit bright green energy bolts from either her hands or her eyes. Unlike the apathetic Raven , Starfire is a generally happy and naive person with an endlessly sunny disposition, and is relentlessly kind and polite to everyone, even to her occasional foes in battle. A new element of Starfire's personality is that she expresses interests in fashion and self-maintenance to upkeep her appearance, such as by giving herself spa treatments  and making and designing her own clothes.
She is voiced by Tara Strong. In " The Left Leg ", Kitten can be seen robbing a bank fairly easily, as she walks out complaining that the bank made her carry her stolen money. Eventually though, the Titans show up in their new Titan Robot. Although the crime is not even that urgent, Robin tries intimidating her with his left leg capabilities. The wannabe criminal drops her loot when Robin goes overboard and destroys buildings and her car. Kitten is about to flee when Robin accidentally breaks the robot, dismantling it and she escapes with the money without a scratch. She makes a cameo appearance in " Yearbook Madness " where Robin imagines her in a photo in his imaginary yearbook. Apart from these appearances, Kitten only has minor cameos throughout Season 3. In part two, she is seen dancing with Speedy. After Raven curses Beast Boy 's love song to her, Kitten chases Speedy while using his bow to shoot arrows at him.
