The War Machine is often associated with Iron Man in the Marvel universe. It was designed as a more militarized version of the Iron Man suit. Rhodey, Tony Stark's friend, pilots the War Machine. It has powerful weaponry and advanced armor capabilities, being used in various battles against villains. It represents a more combat - focused approach compared to Iron Man's suits which sometimes have more of a focus on innovation and quick adaptation.
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.
