| SpongeBob SquarePants|
|Voice actor:||Tom Kenny|
SpongeBob SquarePants is the main character of both the Houseters Pokemon Series and is believed to be based on the protagonist of the first generation Pokémon.
SpongeBob's main goal in life, as described in the first episode, is to be the world's greatest Pokémon Master. SpongeBob began his journey at the age of 10 as a warm-hearted and well-intentioned but stubborn, rash and amateur Pokémon Trainer. He was forced to accept the cheeky Pikachu from Professor Plankton as his starter Pokémon because he carelessly broke his alarm clock in his sleep and woke up late on the day he was set to get his first Pokémon. He was determined to achieve his goal, however, and when Pikachu saw that he was willing to compromise his own safety to keep it safe he formed a strong bond of friendship with Pikachu. This would set his course for the future.
SpongeBob is an only child that lived with his mother, Margaret SquarePants, until he left for his Pokémon journey at the age of ten. His father has not been introduced. The anime suggests that his father was once a Pokémon Trainer who began his journey in Pineapple Town, and that he is still living. In the original, he is also confirmed to have a grandfather, and his son (SpongeBob's Father) followed his footsteps. An interview with the series' storyboarder confirmed SpongeBob's Father is a Trainer on his own journey. According to the same storyboarder, SpongeBon's father may or may not be introduced in the series, depending on its necessity to further SpongeBob's maturity and development as a Trainer.
As a Trainer, SpongeBob has captured and befriended a sizable number of Pokémon over the course of the anime. His philosophy on training is that Pokémon are individuals and that a combination of trust, friendship and hard work are needed to overcome adversity. He seems to battle best with Pokémon that are similar to Pikachu: ones that are speedy and maneuverable, yet able to perform high-powered attacks; however, he is willing to work with any Pokémon that comes into his care. SpongeBob's battle style is generally spontaneous and fairly unorthodox, and his Pokémon often reflect these traits.
