Buff 100kg kangaroo in Australia can knock you out in a fight

Standing almost two metres tall and weighing at least 100kg is this extremely buff kangaroo that looks like it can knock you out in a boxing match.

A gardener said he was walking his dog when he came face-to-face with the huge animal bathing in Boodjidup Creek, Margaret River in Western Australia on Oct 10.

Jackson Vincent, 27, saw the "huge roo" standing in the water and added: "He was one of the biggest I have ever seen".

Photos of the kangaroo that Jackson posted on Facebook rapidly went viral, with netizens pointing out its "bodybuilder-like muscular shoulders, biceps and chest and threatening posture", reported The Telegraph.

Jackson also said: "His claws were really big - they were as long as my hand. That for me was even scarier than his muscles, they looked nasty.

"I definitely wouldn't like to take him on in a boxing match."

According to CGTN, experts think that despite the kangaroo's amazing physique, it had most likely jumped into the water because it was afraid of the dog.
