Thundering Return of Thundering Doltson

Rockhoof, upon his rescue, has returned to his home after hearing what it was like after so many years, only to find to his horror that it is a deadlocked land of war against his descendants in the Great Helm and the returning Thundering Doltson, who has discovered something that made him quite nearly-unstoppable. He has gained a magic enchantment that makes him literally invulnerable, invincible, gave him Herculean strength, and has turned many other Minotaurs into godly-bound foot soldiers out to take revenge for the loss of the Minos Stone and Minotaur magic since the death of his father. As Rockhoof escapes with his life and the Minotaurs are in the process of hunting him down, he asks the Mane Six and Lodgers for help, but even then, Thundering Doltson proved that he's no longer a COMPLETE dolt as he destroys the Friendship Castle, and aims to do the same to Canterlot, and the Crystal Empire, thus destroying the capital and the source of all love in Equestria, crippling them and leaving him with a good enough stepping stone for revenge. With help from the onocentaur whose power Doltson stole to make him thus way turned into a battlemage named Coal Seam, they may have a chance to stop Doltson once and for all.
