Effect: The user covers part of their body (or the entirety of it) with steel scales to dramatically increase both their offense and their defence. More resilient against regular flames.

Training/History - Well, lets just say Tibodico was in a fight, and it wasn't looking good. There were two men, both higher rank then what he was. He was out powered, and out numbered. With no other options, he turned to defence, nothing left to do, but to try and keep himself alive for as long as possible. The two men seemed to be using some sort of sword magic. Evading was just too much work, so a new tactic was in order. One of the attacker suddenly got behind him, about to slice poor Tibodico. In a last minute effort, iron like scales erupted from around him. However this was not enough, the sword seemed to cut straight through with ease, how it happened was beyond the blind boy. It seems his scales were no match compared to these people. They continue, slicing, stabbing and inevitably, slowly killing. He was being slaughtered. It would have all been over then and there if it weren't for Metsu crying, her tears seemed to push Tibodico over the edge, never did he want for her to be sad. His anger raised to the point beyond return, its not often that he gets like this either. Reaching into his pocket he pulled out an iron bar, eating it speedily. With his magic power now restored,he again used his Iron Dragon Scales. Pushing more Magic power into them then before. And it must have worked as well, because the next attack stopped dead on his forehead. Sure it still hurt, but they would never know that. With his anger still rising, he charged forwards, attacking the two with his bare fists. Easily breaking a few bones. His strength had increased as well as his defence. After finally calming down, the two ran. And Tibodico immediately went back to Fairy tail to get his wounds treated. Today was a very good lesson indeed.
