Temeraire (series)
Much more common than heavyweights, these dragons make up the bulk of any country's aerial forces. Middleweights range in weight from 10 tons to 20 tons. Yellow Reapers can weigh as little as 10 tons (with a maximum weight of 17 tons), making them one of the smallest middleweights. British Parnassians are said to be large middleweights, weighing around 18 tons on average, very close to the minimum weight of a heavyweight dragon. Middleweights are much more likely to show special offensive capabilities, such as spitting acidic venom (Longwings), or breathing fire ("Flamme-de-Gloire") than heavyweights. Middleweights tend to be faster and more agile than heavyweights, although if lacking special abilities, they are unlikely to be able to match any heavyweight in a fight.
