What would win between a Diablos and a Rathian?

Ur thoughs on this all

diablos because it can go underground and attack the rathian that way

Ye but a rathian could do the tail wip attack right at the same time it came up

good point

That would also most likely poison the Diablos making it weaker, although if they both charged a Diablos would take out the ian although if they took the battle to the sky ian would most likely win do to the fact that diablos have poor flying skills its hard to tell hmm.....
