Galahad was the son of Lancelot and Elaine. Lancelot was the epitome of male beauty in the old Welsh era, while Elaine… wasn't the pinnacle of female beauty, but she was definitely up there.
What happened when two pretty people gave birth to a child? Well, putting aside the various other factors that go into genetics that is.
It was likely that their child would be extremely good looking as well, and this showed in Galahad. He had his father's dark black hair and his mother's hazel eyes. His face was well lined for a boy who should have chubby cheeks. He was taller than most kids his age, standing at 5 foot 0.
There was, shockingly, no flab on his body and he looked as toned as an adult.
Still, one could just tell his age and personality by how raucous and immature he was.
"Hehehe, look at how strong I am! I'm the best Knight of the Round Table hahaha!!"
