Thor (ScrapTD)

Thor (sometimes called Triple Trouble) is the last barrel in ScrapTD and costs 100 Bricks to unlock. It was introduced in the 1.1 update.

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.

Overall use
Thor is the best barrel if not, the most sturdy barrel in this whole game.

You should 100% upgrade this bad boy to level 10 and above because it's a tanky beast which can be one of the most dangerous and hazardous barrels in this game if you combine it with Chrome and Not Too Fresh.

Just like Chrome, you can use aggro abilities like freeze or speedy barrels to make it devastatingly powerful or possibly the "calamitous" rush for your adversary once their Defense Boost is down.

And considering how strong it can be, it's just unkillable, invincible, immortal and indestructible simultaneously once you spam this barrel with ease!

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.
