Latios has mostly the same body shape as Latias, which is highly aerodynamic and shaped like a jet-airplane. However, he has a larger build and is heavier than his counterpart. His lower body is blue instead of red and features the same triangle-shaped marking that Latias has, only red. The rest of Latios's body is gray instead of white. Latios has flatter ears and narrower eyes than Latias. The gray spot in the middle of Latios's blue face is shaped like a tear-drop. Latios also has ridge-shaped features on his rear, which may either be rudimentary feet or tails or some sort, which differs in shape to Latias's. Like Latias, Latios's forelimbs can be tucked into his body in order to reduce air-resistance when in flight, increasing his aerodynamic properties.
Latias is a bird-like dragon Pokémon. She has a highly aerodynamic body, with the shape of a jet airplane, which lets her fly at topflight speeds. The lower half of her body is red with jet-plane wings and stubby feet. Latias has a blue triangle-shaped ring on her chest. Latias's white and red arms can be tucked into her body in order to reduce air-resistance when in flight, further increasing her aerodynamics. The upper-half of Latias's body is white. She has triangle-shaped ears and a red face with a white pentagon in the middle.
You're design is very simple and elegant. I like it.
