Okay I couldn't get the concept of fat kyle out of my head, so here he is! Call it an AU, because I'm bound to doodle more at some point ahaha

About Fat Kyle (the "what if" desc.):

Kyle has a lot more self-confidence than Chuck, so were he the one in the relationship to be gaining more and more (or if they were gaining together), he'd grow more and more full of himself with every pound. Kyle wouldn't need reassurance from anybody; he already knows he's hot. The bigger the flamingo, the bigger the ego--that's how it would go. He's the kind of bird who stares back aggressively when stared at in public.
He's the kind of bird who would slap his ass or smack around his love handles or moobs to get a rise out of gawking passersby.

Kyle is also a very tactile bird who loves touching and begin touched by his partner. The more surface area available for touching, the better, really. Kyle would absolutely bask in the pleasure of Chuck sifting through his heavy rolls and would demand cuddles and attention and time in bed whenever together. While Chuck is bashful and sometimes giggly when it comes to belly rubs, Kyle would be aroused by it in a rather gluttonous and lustful way.

Thin Kyle is pretty down to Earth, albeit cocky sometimes, but fat Kyle brings out his sinner sides of exaggerated Lust and Vainglory/Pride. Chuck is more balanced and wholesome no matter what weight--while he does change, he never strays too far on the wrong path.

So, what do you think of fat Kyle? ;]
