[i]*sounding like Deathbattle Wiz during a scientific scene*[/i] SpongeBob has fought Sandy for minutes and put up a fight, and he even went over 3 days being constantly pummeled by Flatz, who is so damn scary he was able to turn his dad into his own slave. He also has extremely strong teeth, which he has used to crush metal chains, to climb up buildings, and even to slice cheese. He can also shapeshift, and his body's cells are completely independent of each other. He can squeeze himself into a trashcan, turn into a giant pushpin, and he can even grow extra arms, eat them, and then make them dance. But Patrick has survived flying into a sand mountain and having all his limbs ripped off, falling into a 50 foot hole, climbing out, being hit by a bowling ball back into the hole, then having a giant steel wrench being dropped on his head, and he even lives under a rock that crushes him every time he enters it. He's also has incredible regeneration. His head was completely obliterated after he ate explosive gum, and it had completely grown back in the next scene. And that time he lost all his limbs, he had completely healed in under seven minutes. Both of them suffer from the same weakness however. When Plankton snuck into SpongeBob's head to try to probe his brain, it was barely larger than plankton, who is only 1/6,000 of SpongeBob's mass. And when Patrick fell off a cliff and was decapitated, his body accidentally replaced a piece of coral, and it made him WAY smarter. Alright the combatants are set.
