The two of them began walking through the facility. This is the first time that Legion-5 is allowed to walk through the facility on his own feet. He was always in a cart the previous times they had to go somewhere. 

He has grown taller too. He is a little over a meter in height which is more than twice his previous height but he is smaller than battle sage monkeys which means he is shorter than the average height in the realm. He can even be considered a dwarf. Except that he is more ugly than a dwarf. 

He has two eyes, a mouth, and two holes on his face for nostrils. He doesn't have a nose or an external ear. Just two holes on the sides of his head that lead to his inner ear.
