WATCH: Two HUGE Monsters Meet In The Ring & One Guy Sleeps

We all love a battle between two titans of epic proportions, and especially ones that end in savage knockouts…

When it comes to knockouts by division, super-heavyweight and heavyweight are the ones to watch. Even a stiff jab can disconnect a fighter from their consciousness when competing at 265 pounds and above.

It’s over to the world of kickboxing for the subject of today’s article. Raul Catinas, now a mixed martial artist, was one of the most feared strikers in the kickboxing heavyweight division.

Raul Catinas KO Ricardo van den Bos (video below)

‘Iron’ Raul Catinas fought against fellow giant, although much larger, Ricardo van den Boes at ‘Superkombat.’ The two Goliaths of the K-1 world collided, with devastating effect.

The knockout came early in the first round, and will surely go down as one of the most brutal in kickboxing history. Check out the video of Catinas’ brutal knockout victory on the Youtube player below:

Wow, now that was a nasty knockout for sure. When talking about incredible kickboxing knockouts, you can’t forget a guy like Alistair Overeem. Now competing for the UFC, ‘The Reem’ is arguably the most decorated striker in MMA.

Coming off a rather embarrassing and one-sided loss to Stipe Miocic at UFC 203, Overeem is arguably the most dangerous K-1 heavyweight of all-time. It’s easy to forget this when you see his current form in MMA.

Alistair Overeem

This awesome K-1 highlight video of Alistair Overeem perfectly displays how dangerous his striking really is. Made by Youtube user ‘MBish,’ this Alistair Overeem K-1 highlight has nearly 200K views.

Let’s help him get over that 200,000 views mark. Check out the video of Alistair Overeem crushing his K-1 opponents. ‘The Demolition Man’ was at his finest while competing in Japan, albeit a little bit ‘juiced’ too.
