I did Latios just before remaking Latias. Latios is about twice the size of Latias
The arms were a lot easier than Latias because of his size.
After doing 3 total papercrafts in 2 weeks, I am done for now and I am hoping to do the Legendary Beasts next (Entei, Raikou, and Suicune)
I hope that you all enjoy this craft!
