3. Black Widow Commandeers A Chitauri Flier (The Avengers)
Marvel StudiosNow, this move could have ended up with Black Widow having her arms or face torn off but, as it ended up working out just fine, it was actually rather awesome. It occurred during the epic battle of New York City, when the Avengers realised that they needed to reach Lokis portal to stop the invasion of the Chitauri. Unfortunately, Loki's portal was way up on the top of Tony Starks tower. This would be easy enough for certain characters (Thor, Iron Man...) to reach, but they were otherwise occupied. It was therefore left to Black Widow, but the large number of Chitauri warriors were preventing her from getting up there on foot and, as a result, she opted to take a potentially suicidal route to the the portals power source (saying itll be fun!). Carefully watching the Chitauri fliers zooming past overhead, she used a bunk up from Captain Americas shield to grab onto one of them mid-flight, despite the high speeds that could have ended up with her being badly hurt or killed. She boarded the flier, killed the alien pilot and commandeered it.
