Thor (ScrapTD)

Thor (sometimes called Triple Trouble) is the last barrel in ScrapTD and costs 100 Bricks to unlock.

Strategical use
Thor is the strongest barrel ingame, and therefore the "undestructible" barrel of the game. For best damage, use it with Chrome when the Thor barrels already can get through the defense without getting killed, shielding the Chrome barrels which deal 5x as much damage each.

Trivia

 * In Scrap Clicker 2, this barrel's name is "Triple Trouble". It's not known at all why it was changed to "Thor".
 * There's a barrel in Scrap 2 with the name Thor, #102.
 * Maybe the name Thor was chosen because it's a strong barrel.
