One possible plot could be that Harry gets his metal arm during a battle with Death Eaters. The arm could be magically enhanced, with runes inscribed on it that give him new abilities like being able to sense dark magic from a distance. He then has to learn to control these new powers while also dealing with the prejudice from some in the wizarding world who see his metal arm as something 'unnatural' in a magical setting.
In a 'Harry Potter has a metal arm' fanfiction, the plot could start with Harry being experimented on by a rogue group of wizards who are trying to combine magic and Muggle technology. The metal arm gives him the ability to communicate with magical creatures in a unique way. He then uses this newfound ability to gather an army of magical creatures to fight against Voldemort. Along the way, he has to overcome the doubts of his friends who are initially skeptical about his new - found powers and the metal arm.
