Monstrous nightmare are munch faster then thunderdrum so they should be able to doge the attack of sonic roar.

Thorndao weights about 900lbs which I doubt looks like 1,000-1,200lbs. But monstrous nightmare can hold their breath underwater for while to fight. He can swim in high speed slough he won't be able to breath fire when dragon head is wet. But with nightmare speed will dry fast enough to use fire balls. And nightmare wing blast can hit them to the ground. Longest nightmare will count on their speed to doge their attacks.

So nightmare will win.

Thunderdrum the size of thornado and nightmare like hookfang will have the advantage. Also tidal class dragons can't stay out of the water to long.

Nightmares have have high stamina and endurance.nightmare could use their weight like Bodyslam.
