"I don't know, that's just the way I've been built, it's just a different mentality so, yeah I'd like to go in and know I'm going to cause some damage.
He added, when asked whether he respected 24-year-old Parker: Yeah, [I'm] giving him respect but he ain't beating me..."
The 26-year-old Joshua, an Olympic gold medallist in London in 2012 and also undefeated as a professional, said he would take on Parker without hesitation.
"Yeah, that fight is going to happen, 110 per cent... 110 per cent. I've been watching Parker since the Commonwealth Games in 2010. I've known of Parker since then, Parker is not new on my radar. Parker ain't this professional kid from New Zealand, I've known him since he was an amateur. I know a bit more about Parker than a lot of people think."
Joshua is respected within Parker's camp, with trainer Kevin Barry saying recently he thought the powerful Joshua had improved significantly over his last couple of fights.
However, he hasn't been in the ring with anyone as tough or as talented as Takam, and questions remain about his chin. A single power punch from Dillian Whyte rocked Joshua when the pair met last year, but Joshua recovered to record yet another knockout victory.
He has 16 in his 16 professional fights.
