Mainly because it just sounds freaking amazing. I'd love to see the art department work one of these out!
And on a more competetive note, Dragons are pretty risky business in this meta, as are bugs with the ubiquitous Stealt Rock. On the flipside, Dragon is an amazing attacking type, and the Bug type has some niches I'd like to see explored.
Please don't let this be bug/dragon. Outrage and Draco Meteor have always been used in OU and by this we learn nothing. Bug/Psychic fits the risky role better. A bit miffed about Electric/Psychic not getting to the poll.
