In The Elder Scrolls 5: Skyrim, you can kill a dragon and use its stolen soul to power your Dragon Shouts. This on its own is fairly awesome. The thing about Skyrim is that it also features a race of cat people, the Khajiit. And hey, there's another notable pop culture icon that features shouting cat people: Thundercats.
One tech-savvy fan, YouTube user Voraxith, saw this connection between the two and mashed them together with a Skyrim mod that converts his Thundercat emblem-wearing Khajiit's Storm Call shout into Lion-O's "Thundercats, ho!" battle cry (via Destructoid). THIS right here is why all of us should be playing Skyrim on PC.
