rahoo is not asoon or a monster. its just the new version of tep 3 radoo that made him like that. rahoo in the farytale and old tep 3 radoo is half giant half god. not asoon like new tep 3 radoo nowdays they make everything wierd and they dont follow the true farytale of these charactor.
and a asoon is a demonic ghost figure that have a teeth like a yak that live under the ground. well this is from the old tep sungwahn in the 80's.
