Stone Wall is a type of characters whose defensive capabilities by far exceed their offensive ones. In terms of the VS Battles Wiki, this means that their Durability tier is significantly higher than their Attack Potency. This is an opposite term for Glass Cannon.

For example:

• Robbie Rotten can survive attacks from Sportacus, but he himself is only Athlete level.
• Individual members of The Stone Army can take hits from The First Spinjitzu Master, but struggle against characters with Large Town level durability.
• Botamo can nullify attacks from Son Goku, but is barely able to knock him off-balance.
