Strong Bad rules the land of Strong Badia, a barren field behind the dumpsters that is completely devoid of any sentient life. His favorite saying is (or was for a time) "holy crap", though he hates when people use the word crap when signing emails. He frequently mangles words, as seen in army. ("We're a one man army. Er, a three man one-y. Three-to-one-marny?") It has also been implied that he wets the bed, a fact that he attempts to cover up with little success. However, he seems to sleep instead on the couch in his basement, frequently mumbling video game titles as he wakes surrounded by bags of Potate.

Strong Bad talks a big line, claiming to be a criminal mastermind, a muscle man, and totally popular with the ladies, though there is little evidence of any of these claims, and no shortage of evidence that they are all untrue. Strong Bad refuses to acknowledge this however, and continues unaffected with his delusions of grandeur. He is convinced that Marzipan likes, or has a crush on, him when in fact she "really doesn't like him at all." Due to his delusional opinions about himself, much of what Strong Bad says is obviously untrue.
