"Plankton is the only likable character left on the show"
Well then, excuse all of these horrible deeds he has done in the modern episodes.
* Forced everyone into a brutal sled race that led to their near-deaths at the hands of a claymation yeti
* Destroyed the peaceful Jellyfish Fields to build a superhighway over it, sending jellyfish to attack savagely
* Imprisoned dozens of civilians in a gladiator arena and later in a cave
* Enslaved peaceful cave dwellers to do his bidding
* Teaming up with several known criminals and even supervillains
There is nobody likable on SpongeBob anymore.
