A photograph has been snapped of a man-sized kangaroo flexing his massive guns while hugging a soft toy bunny.

Roger, an alpha male at the Alice Springs Kangaroo Sanctuary in the Northern Territory, was gifted his new friend by a fan.

Sanctuary manager Chris Barnes said the kangaroo quickly became attached to the bunny, but soon tired of it.

'Roger received the bunny from a fan. I thought Roger would probably like to play with his soft toy,' Mr Barnes said.

'When I gave it to him he snatched it off me really quickly and proceeded to attack it, giving it a "bear hug" and wrestling it, even hugging it and kicking out as he would do in kick boxing match, he's an expert kick boxer.'

But Mr Barnes and his team made the mistake of trying to take it away from him.

'After about 10 minutes of not giving up his bunny Roger lost interest in it, but when I tried to take it off him so he tried to attack me instead, which is a daily ritual for us,' he said.

'Baby kangaroos are often found still alive in the pouches of dead kangaroos out on the roadside,' he said.

Being an alpha male, Roger is often very protective of the female members of his group.
