The Wily Firewall is an advancing wall of fire originated from Torch Man's stage in Mega Man 11.
The Wily Fireball is as big as a screen and advances from a direction to another, stopping when the player character goes to a disconnected screen. It will kill the player character and enemies, ignite Oil, detonate TNT, and melt Ice Blocks. Its initial point, its trajectory and its speed can be defined in the Level Builder.
- When announcing this level object, WreckingPrograms did puns around the word "Firewall", on its sense as a wall of fire and as protection against virus in software.
- The 8-bit sprites for the Wily Firewall were designed by Schmidkalkan.
