Character: Female Charizard (Nintendo's Pokemon)

While this old and lovely Charizard enjoyed having lots of meal to stuff her belly playfully, she's very wise enough to defeat her immobility by building up her move (Flamethrower, Fire Blast, Solar Beam, etc. Whichever you like to think which one she used.) to keep herself as light as a feather, even if she bloats her belly even further. She sure knows how to unleash the Silver Vixen in her, lol.
