Strom Steel is similar to earth. It is not exactly like Earth but it has similar features. Strom steel is made up from what earth is made up from. Above the core is Earth's mantle, which is made up of rock containing silicon, iron, magnesium, aluminum, oxygen and other minerals. The rocky surface layer of Earth, called the crust, is made up of mostly oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium. This is what Storm Steel is made out of.
