Notes:

The idea here is that, being a Kryptonian, she was already a being of unfathomable power. And here the Infinity Gems aren't worn externally, they were implanted into her. As a result her body has absorbed so much Infinity Gem energy it has caused her body to increase in mass from the surplus power, like an overcharged PSP battery that has swollen up. But don't worry she won't suddenly explode, afterall she wasn't made by Sony…

Also if you're wondering where the Soul Gem is? Well, I kind of already gave it to someone else….
