He's baby
In the lore, Biolizard would have grown too fast and too powerful, thus failing, but Gerald used Doom's blood as a stabilizer for Shadow. With that in mind, In my HC he grew to near adulthood rabidly, maybe 2 years or something, but not so fast that he would have been overwhelmed by the power. He grew in spurts, each stage gradually slowing down.
There will be more baby Shadow, I promise. Still trying to figure out how I wanna draw maria... this was a while ago, though, so I will try again soon.
Kids do grow up fast though, I once saw a boy grow a foot in like 3 days. Wild stuff, tbh.
