“Unlike many superheroes, Batman has no superpowers and instead relies on “his own scientific knowledge, detective skills, and athletic prowess.” Batman is physically at the peak of human ability in dozens of areas, notably martial arts, acrobatics, strength, and escape artistry. Intellectually, he is just as peerless; Batman is one of the world’s greatest scientists, criminologists, and tacticians, as well as a master of disguise, often gathering information under the identity of Matches Malone. He is regarded as one of the DC Universe‘s greatest detectives.”
“Rather than simply outfighting his opponents, Batman often uses cunning and planning to outwit them. In Grant Morrison’s first storyline in JLA, Superman describes Batman as “the most dangerous man on Earth,” able to defeat a team of superpowered aliens all by himself in order to rescue his imprisoned teammates.”
