Todoroki Shouto [轟 焦凍]

[he's grabbing a couple of vials to start at least]

Red: Can only speak in compliments (tastes like strawberry)
Orange: Can only tell the truth (tastes like peach)
Yellow: Can only tell lies (tastes like lemon)
Green: Has to physically touch someone while they speak. If you try to speak, you'll get the desire of touch. No touch, no speak! (tastes like apple)
Blue: Cannot physically stop talking unless they clamp their mouth shut physically. (tastes like blue raspberry)
Purple: A word appears over your head to reveal what your current mood is. More intense = more words. (tastes like grape)
