Any chromatic dragon would straight up try to kill the party for their audacity and then the wyrmling for allowing itself to become a pet, I would thinkĭungeons & Dragons being a fantasy world, I say go at it.

All dragons are extremely proud and even metallic dragons would not react kindly to finding a group of adventurers keeping one as a "pet", even if it was one of their chromatic, evil kin. There's the ordeal of obtaining the egg, making a knowledge check or finding the info on how to nurture the egg in order for it to hatch, then almost constantly nurturing/protecting the egg until hatching, the bias and paranoia that would come from NPCs after seeing a chromatic dragon "pet", numerous animal handling/persuasion checks to keep the thing in line or to "tame" it, protecting it from danger, keeping it happy by giving it treasure, but more importantly the looming danger from other dragons. The amount of work I was thinking of having players go through for this payoff would be immense. So my thought was that the wyrmling's alignment could end up being what its caretakers try to imprint on it, along with what it observes and compare that to its natural alignment.

It even gives a good aligned green dragon as an example. The MM states right away that alignment on monsters can be changed and the given alignment is simply the default. You may also take inspiration from the film "Dragons" which may help you figure out how to handle the taming thing and the social aspect of it, depending on your setting obviously.That was kind of my thought, was that the players could try and "tame" the dragon and temper its chaotic nature through various skill checks over time. It's a nice concept and it's not inherently breaking anything if you plan the campaign accordingly.Įdit: the egg hatches when you as a DM deem appropriate, no need to be specific about it.

I'd say that the egg is medium sized and the dragon hatches already with the stats of a wyrmling, with some work I'd allow players to tame its chaotic nature, but not in the early levels, and it would take large amounts of downtime.
