Wild buffalos at Uda-Walawe national park, Sri Lanka.

Water buffaloes are notorious for for their strength. They have been domesticated and used in South Asia for millenia. They are also very stubborn, very impulsive and stupid. They stick together as herds. They are dangerous animals to meet when they are together as a herd, in the jungles.
