It is not clear how Kree physiology differs from human physiology. Their skin is typically blue and their eyes red (with exceptions on both counts), but they otherwise appear to be human. Some have demonstrated superhuman strength and durability, but cybernetic enhancement seems to be common in Kree society, so it's not clear which of their superhuman attributes are technological in nature. Superhuman healing ability does appear to be an inherent trait, however, and extracts from their tissues can be used to induce rapid healing in humans.
Kree technology is far more advanced than Earth's. They have advanced space flight, weaponry, medicine, and communications. Cybernetics appear to be widespread and accepted in Kree society (and in their region of the galaxy in general).
The Kree were embroiled in a prolonged war with the Nova Empire, but they have negotiated an uneasy peace. They appear to be engaged in an ongoing conflict with the Skrulls, who they are trying to wipe out. They have a space fleet of undetermined size. At least some of their warships are armed with missiles designed for planetary bombardment.
