The Thunder Dome is a community-created cosmetic item for the Demoman. It is a helmet with five spikes across the middle from the front to the back and a visor. It is very worn, with chipped paint and a big dent on the right side.
This item has three styles, named "Bombin'", "Chargin'", and "Jumpin'". The "Bombin'" style paints the sides of the helmet team-colored with an orange or yellow stripe (depending on the team) following the spikes, and also makes the visor either orange or yellow; the "Chargin'" style paints the helmet black with a white tire-like stripe following the spikes, and makes the visor team-colored with some cracks on the left side; and the "Jumpin'" style removes the dent and the spikes, paints the helmet orange with two white stripes running from the front to the back, adds the Demoman's class emblem to the sides, and makes the visor the same shade of orange as the helmet.
The Thunder Dome was contributed to the Steam Workshop.
