User blog comment:Ion Eduard Andrei/Monstrous nightmare vs Thunder drum/@comment-24413325-20140701194354

Thunderdrum will totally win because

1. it's sonic blast is strong enoug to hit anything away from it's way. (and this roar is around 200-310 dB)

2. the thunderdrum is one of the strongest dragons that ever exist, and much stronger than a monsterous nightmare.

3. thunderdrum's sonic blast is can blow out m. nightmare's fire....

4. thunderdrum's has very powerful fire too, they can fight with it too

5. the thunderdrum is can avoid night fury's fire, so it can avoid nightmares fire too..

soo thunderdrum wins
