For a guy with a napoleonic complex, you can't really say Cloud has a dull side to him. I remember getting a laugh out of his "Miss Cloud' stint... and I I remember using the sackboy costume the most when I play Little Big Planet.
Sephiroth: HHAHAHAHAHAHA!! I Knew Cloud was emo But Seeing him in a dress Is Priceless! Cloud: Shut Up! How would you feel if you were in that situation! Seph: Probably Just Killed them Before they get a chance Oh wait that's right Already did! especially Aerith! HAHAHAHAHA!! Cloud: I'm gonna Kill you! Seph: cloud Obviously You can't. Cloud: I did it twice! Seph: And yet I Still Come back. Cloud: damn you!
