I can't remember how he put it exactly but one reviewer I recall said like spike this dragon was likely a nice guy but just really sleepy and tired when rainbow kicked him. I'd say anyone would be more than a little upset if a someone,a stranger or otherwise just walked in the room and smacked them in the face while they were trying to sleep. Sweet picture.
The big guy just wanted a place to sleep, and then these ponies walk in and start bothering him, tried to steal his hard earned gold, and kick him in the jaw after he had just got back from the dentist cause he had a problem with his fangs and had to get them pulled, and now he can't even breath fire, and then Fluttershy goes ahead and yells at him like she's his mother who he lost when he was a child to a big gray dragon who terrorized his home land an forced him to leave.
Actually Dragon scales are generally said to be very tough, how strong exactly? well they have been known to be resistant to most every weapon, so my guess is there scales have an outer coating of solid carbon, don't even get me started on how strong Carbon can be, so an RPG on a dragon that large might irritate it and push it back about an inch or so but not do any actual damage, in other words YOUR ARGUMENT IS INVALID! DRAGONS RULE!!!!
