Also, don't forget that Erde has access to only raw material, very crude and of low quality. I'm pretty sure that one hail of rockets from Edmund would flatten any wall build by Erde in seconds.

Also, this is a good point. About the only materials in the ground sturdy enough to withstand any sort of punch or bomb from these characters is corundum and diamond. Access to diamond would require Erde traveling down about 100 miles to get his hands on the raw newly formed and large enough to utilize diamonds. There aren't enough diamonds on the surface of the earth to utilize in the way Erde does. Corundum is also not a super prolific material. 

While Erde has range, I made sure to make it so he's fair to fight. Yes, he can make a thousand pillars of stone and dirt. But no. That's not going to slow down any high tier. Any attack that could stop a high tier is also certain to be avoided by that high tier. 

Example: 
Ripping a vein of iron out of the ground to trip Green's Mech. This would trip the mech and allow Erde access to destroy his foe while he is on the ground. Using the numerous stone tendrils to pull it into the earth before it can get back up to resist. Then using the pressure of the dirt to crush him. 

BUT.

If Green's mech saw it coming, it would just accelerate fast enough to rip right through the vein. Rather than letting it trip him.
