14 More Marathon Boss Fights That Will Test Your Limits

King Krusha K. Rool – Donkey Kong 64

K. Rool has always been a headache to fight in the Donkey Kong Country series due to the multiple phases that one has to go through without dying. He’s no different in Donkey Kong 64, except this time it’s a five round boxing match. Each round requires a completely different strategy (since a different Kong family member is fighting) and losing on any will start it all over again. All in all, it’s a good 15 to 20 minutes even if you’re moderately skilled.
