Yes... Code Geass is an anime which aired years ago.. But it's one of my favourite.
So i'm giving credits to this
Fabulous anime :)
If you don't know about Code Geass, I can tell you EVERY thing about it. Okay, just joking, it would spoil all the fun :) . Here's a pic :

The middle and almighty one - Lelouch . He has many fangirls :) (Yes, I am one too!)
Code Geass is about a Britannian (Lelouch) who vowed to destroy Britannia because of a promise he made to his friend , Suzaku.
(Suzaku is at the Bottom-right). After Suzaku was shot for disobeying orders, Lelouch was given the power of Geass :

After a series of events, Lelouch becomes the infamous masked "Zero" - who fights against Britainnia ; And Suzaku becomes the pilot of a new prototype Knightmare, Lancelot - to fight against the 11s , those who rebel against Britannia.
Lelouch was exiled from Britainnia when he was child, and lived in Japan with his sister - Nunally .
He began to grow an immense hatred towards his father , the ruler of Britannia , and Britannia as well.
He is VERY smart even though he always skip classes.
And of course.. really handsome as well ;)
I think that Code Geass is a pretty cool anime because of it's original ideas.
They even have those "Knightmares" that look somewhat like Gundam. (COOL.)
Even though the first season is nice, I would recommend you to watch Code Geass R2 right after you watch this.
IT IS TOTALLY AMAZING. So , I really recommend all of you guys to watch this anime. It's really cool.
I like it when they say "All hail Britannia!" . Sounds really awesome.
WHAT ARE YOU WAITING FOR?~ Watch it !
Or you could watch it again if you already have ;D
