Powers
Runs after Defenses (cannons, AT, etc.) and lights them on fire, then runs to the next and lights on fire until it dies. When it lights the building on fire, it doesn't do damage, just the fire burning it does. It is able to do damage to a building without the troop doing physical damage to it. The defense can still work until the defense breaks.

Details
-Other troops see the fire and avoid the building to prevent catching on fire as well.
- It takes as long for the building to catch on fire as long as a WB to drop its bomb.
-It can't burn down TH, Army Camps, and Lab. (Too Big)
-Destroys Freeze Spell effect and takes longer to burn, also freeze spell takes out Pyro effect

Un-Decided Powers
-Pyro twins, have one with shield (to protect) (Can't shield from behind only in front and sides) other lights on fire
-Let them/ it jump over walls
-Instead of ground troop it is in a Balloon Dropping flaming sticks? Name would be Air Pyro
