In some fanfictions, Naruto could potentially be depicted as a 'war machine'. Fanfiction often takes creative liberties with characters. Some authors might explore a darker or more militaristic side of Naruto, where his powers are used in a very aggressive, war - like manner. However, this is a departure from his more typical characterizations in the original series.
In some comic arcs, War Machine does end up paralyzed. It often depends on the specific plot and events unfolding. Sometimes it's a result of intense battles or unexpected circumstances.
Yes, there might be. The Naruto fandom is vast and creative, and it's not uncommon for fans to create crossovers like this. You can try searching on popular fanfiction websites such as FanFiction.net or Archive of Our Own.
War Machine isn't a pure true story. It takes some liberties and combines fictional elements with loose inspiration from real-world situations to create a compelling narrative.
