For a challenge where you change one letter of a Pokémons name

Zoltres and Marticuno

I would design them, but I'm not exactly sure what they would look like. I chose Mapdos for this as I was able to come up with an idea that I thought fit the name, but I'm not sure what those would look like.

maybe Marticuno because like Walmart.

it would be like one of those baby delivering birds except its grocery's.

Carshadow (marshadow).

This one I might be able to design, but no promises.
