Dragon Companion

 I suggest a potential use for the ender dragon egg and that being the ability to hatch it and own it as a pet, familiar or even as a mount. The dragon's nature may change just like the fox mob when domesticated as a youngling which then becomes a pet for the player; the dragon when hatched may enact more affectionate and helpful towards the player just like a wolf tamed dog. I also have a suggestion for the golden dandelion in regards to the hatched dragon companion, in that the dragon may have 2 forms, a juvenile form in which it acts as a familiar, flying around and torching or attacking mobs while sticking close to the player - it may stay in this form using the golden dandelion or a special modified variant, allowing it to act solely as a familiar like the allay or it can reach a more senior dragon form in which it may be mountable, becoming as big as a ghast or warden, potentially. The player may even have the option in using the dragons breathe attack for making tipped arrows, just like it's tyrant mother. Understandably, since the ender dragon only drops an egg one time which is when it is first defeated, it would be impossible to get eggs for other players in the same world, so i suggest the hatched dragon companion be able to drop eggs as a adult dragon companion which lore-wise may be acceptable since dragons are depicted as lizards and lizards can be parthenogenetic, making the 1st hatched dragon companion become the matriarch for all other dragon companions.
