[Char] Scorpion (supposed to represent the maker)

[Scorpion]

Well, I think that a sandstorm would be unrealistic, because he is only
at places where sand is. And there aren´t many stages with sand.

Who said he can't summon the sand by himself ?
Characters like walter summon water for example by themseves, too ... Or Freeze ice

or he does an earthquake to knock all enemies wich are on ground.

That would be a nice idea!
