While someone has already beat me to the idea of Ingo and Emmet with a cute toy train plush I still wanted to draw my Lati-Ingo and Lati-Emmet with their own (Yes they still have them when their adults) Also I’ll just add my own headcannon here, I have the idea that latios and latias feathers(?)are white all over at birth but gain their distinct colour/markings as they grow/age. This is for camouflage as babies have difficulty controlling their ability to turn invisible so for the first couple of months they are white to match the clouds they fly through, by the time their markings start to appear they usually have control of this ability.
