There's more to Black Ops 2 than simply killing fools and earning prestige levels. Among many other things the game has to offer, there's also the emblem editor which you can use to express your creativity.
The best thing about the editor is that it allows other players to view your emblem when you kill them or disable their score-streaks.
In many ways, having an emblem is so much cooler than being able to spraypaint the ground in CounterStrike or having a Steam avatar on any number of PC games simply because having a well-designed emblem practically requires you to be creative and having the patience to come up with a kickass design with the limited number of tools available.
There's a lot you can do with those tools, limited as they are, and you're ultimately constrained only by your imagination. You can always splatter your emblem with pictures of guns and nuclear symbols, but the more creative among us have decided instead to recreate popular memes or repurpose well-known images, such as making Ironman in the form of an Angry Bird.
If you keep your voice chat on, you can expect to receive a lot of praise for your emblem in the lobbies. It's nice being appreciated for your work.
Without further ado, here are some of the coolest emblems in Black Ops 2.
