A quick study
Jarvis, Tony Stark’s long-suffering virtual assistant, is a pretty useful fellow. As we find out in the MCU series Agent Carter, he’s based on Howard Stark’s butler. He provides many comic moments for the movies, from his very first outing in Iron Man.
In The Avengers we see that he can distinguish himself as a quick learner even in the middle of battle. As the aliens are attacking the group of heroes from all angles during the final battle, Hawkeye notices that they’re not that great at turning corners, and Jarvis changes strategy to help Tony defeat them, leading to the team’s eventual victory.
