ngl i'm not sure i can even think of 5 dragons lmao. i am not familiar with that crowd but lets make an attempt anyway. in no particular order:

• bub (et al) from bubble bobble - i just think they're neat
• that big fat one from the recent dungeons and dragons film - absolute fucking unit. top class
• spyro - ourple
• ridley metroidprime - cool as hell and i am counting him as a dragon
• noivern - just look at it
