Quirk: Sonic Siren  Class:Emmiter/Mutation

while on land the user is able to creat sonic boom force soundwaves while singing or screaming (strength varies depending on emotional state)

while in water/rain the user grows flippers scales,fins and gills and the sonic boom force blasts transform into a hypnotic melody while singing and can cause others to work for them or activate/deactivate other peoples quirks

weakness: sound wave usage leaves the user with a sore throat if held for too long (like 2 hours which is pretty resonable) and when caught in a rain storm will be able to move but motions are clumsy and slow
