Perhaps Harry teams up with his friends in this fanfic. They could set up a clever trap for the Death Eaters. When the Death Eaters fall for it, Harry uses his magic to blow them up. It could be a situation where they are lured into an enclosed space and Harry's spell detonates, causing chaos among the villains.
In the 'Harry Potter Blows Up Death Eaters' fanfic, it might also be that Harry has some sort of magical object or artifact that gives him the ability to blow up the Death Eaters. This object could have been hidden for years and he just discovers its power. He then uses it in a crucial battle against the Death Eaters, turning the tide of the fight.
