Sword Art Online vs The Matrix

Connection:

Both were once normal and ordinary computer geeks and nobodies in real life that got trapped in a virtual reality and turned into black clad warrior fighters and powerful heroes with a variety of weapons and abilities from said digital/cyber/virtual world

Both are the chosen saviors of said worlds and eventually free everyone from said world by overcoming that world's "god". Their most notable trait being their uncanny ability to influence people around them

Both of them met their love (Asuna and Trinity) who they've witnessed dying once

Both their virtual reality names are more popular than their birth names (Kirito's real name being Kirigaya Kazuto and Neo's real name being Thomas A. "Tom" Anderson)
