when Spike is unable to. Angel also remarked in "Sanctuary" that Buffy is "a little bit stronger" than he is, though the humorous tenor of the exchange suggests he may have been understating the difference. The Slayer's strength appears to be largely metaphysical, as it does not seem to add to their body mass and they remain buoyant enough to swim. Melaka Fray is able to pick up an overweight vampire several times her own size and body mass, lift him up over her head with both hands and throw him over a distance of presumably over 20–25 feet, with no downward arc to his trajectory (which was only interrupted due to his hitting a metal grate, which was extensively deformed on impact). The psychotic Slayer Dana is able to, through several violent shoves, knock down a metal door as well as deform the edges of a metal gate as she tore it from its hinges. Buffy and Angel often shows inconsistencies in their characters' physical strength; for example, Buffy was unable to bust open a metal door in "I, Robot... You, Jane", but casually breaks down metal doors in both "The Harvest" and "End of Days". Buffy also been successfully bound by rope or chains on multiple occasions. This has been acknowledged frequently in commentaries and interviews by writers and creators of the shows. However, it is stated by Riley that Buffy gets stronger "every day" and is inferred that she may be stronger due to the fact that she has been activated the longest. Agility and reflexes Slayers are able to move faster and react more quickly than normal human beings. Buffy has been shown snatching a crossbow bolt in mid-flight, dodging gunfire from multiple ranges and setting off a bear trap, but not getting caught in it. At one point Buffy was fast enough to outrun a raiding motorcyclist on his bike shortly after her resurrection. Faith has been shown to dodge shotgun blasts at point-blank range and Dana was able to dodge a tranquilizer dart also fired at point-blank range. A Slayer is capable of superhuman feats of agility. She can leap to great heights; though the maximum is unknown, Buffy was shown to be capable of reaching the roof of the original Sunnydale High in a very short period of time, after running up a sloping wall then flipping onto the roof.
