Olimar's son

Olimar's son is a standard young boy. He seems to be fascinated by his father's adventures and seems to envy him. He is addicted to video games and enjoys them more than studying, in contrast to his sister. Judging by some of his mail, he must be in his teenage years and is anxious about girls. He always yearns for his father to come home and doesn't like when his mother becomes strict because of the pay bonuses, asking his father to come home to fix the mess. He seems to easily be won over, as he asks if he should send in Olimar's bonus check for a piece of spam mail.
