Teen Titans Ticklish Headcannons
Robin
Robin is very ticklish. In fact he is the most ticklish out of the Titans. You can just tease him and he'll go into a giggle fit. He's the main and residential lee among the Titans and mainly Starfire and Terra will tickle him with every opportunity they can get. He's rarely a ler, but when he is, he's the most gentle and merciful out of his friends. His most ticklish spots are his tummy and sides.
Starfire
Starfire is the second most ticklish out of the Titans. She will literally double over in laughter if you tickle her. Drag a feather across her tummy and she'll burst into adorable laughter. She's a very devious ler, as she's relentless and merciless. She won't stop until her desire for laughter is satisfied. Her favorite lee is Robin, and she loves the sound of his adorable laughter. Her most ticklish spots are her tummy and ribs.
Beast Boy
Beast Boy is extremely ticklish. If anyone even slightly touches his soft tummy, he will lose it and become a giggling mess. (BB's laugh is super cute!) He's a remarkable ler, as he will playfully ambush his friends whenever he's in the mood. He's the kind who'll respect boundaries and will ask if he went too far afterwards. His most ticklish spots are his tummy and sides.
Terra
Terra isn't as ticklish as Starfire or even Robin, but she's still pretty sensitive. Her exposed tummy is an easy target for her teammates. Cyborg will literally sneak tickles to her and Raven will do a full on tickle attack on her. She is a merciful ler, which means she will stop when her lee asks. She'll mostly tickle people if they talk her into it. Her most ticklish spot is her tummy.
Cyborg
Cyborg is pretty ticklish, but is better at hiding it after all the Tickle Wars Starfire has had. Be pretty sneaky if you want to suprise tickle him. He will definitely seek revenge. He is the second most devious ler. He literally will tickle his lee until they surrender. He will wreck his lee if they figuratively ask for it.
Raven
Raven is the least ticklish out of the Titans. All she gives out are small giggles and laughs. She still will openly admit it, even if it doesn't affect her as much. She is also the most evil ler you will meet. She's not picky about her lees though, but if they provoke her, she will wreck them and won't show mercy unless they take it back.
