In this episode, Steve goes in search of some of the most powerful predators on the planet. At historic Warwick Castle, we meet the stellar sea eagle, world's heaviest eagle. Our eagle Nikita is an expert at lifting fish up to one third of her body weight out of the ocean to eat. To demonstrate this amazing ability up close, Steve has one of the coolest pieces of tech in Deadly history - a time slice rig. Using this, Steve is able to analyse Nikita's predatory power from every angle. Next, Steve goes head to head with one of the strongest land predators - the bear. Bears aren't just strong, they are incredibly agile too. During the summer they have to catch and eat up to 30 whole salmon before hibernation. Steve puts this to the test by wearing a bear suit and being drenched in water - can he catch as many salmon as a hungry bear? On a mission to find the world's most powerful punch, Steve tries his hand at boxing with a fairground punching machine. He is no match for our professional boxer Isaac though, who gives Steve a few punching tips. However, when it comes to powerful punches, nothing can beat the peacock mantis shrimp. Despite being only six inches long, its punch has the same power as a bullet. We see in incredible CGI what a human-sized mantis shrimp could do to our boxing machine. Steve then reveals its secret superpower - it doesn't just hit with its punch, it also creates a shockwave of energy in the water. Steve supersizes this and blows up a fish tank full of water with some plastic explosives. Finally, Steve comes face to face with his favourite animal in the world - the wolf. At a special zoo in the UK, Steve meets a real wolf and a hybrid wolf, and puts their pack and jaw power to the test - can he win a tug of war with our wolf using a real deer's leg. We then head to the quarry, where Steve shows us how a wolf uses its powerful jaws to hang on to prey by trying his hand at a bucking bronco.

In this episode, Steve finds out which Deadly Predators have the best weapons on earth. Using the latest CGI, we bring the colossal squid to life, test the strength of its tentacles, and show how its mighty beak could slice through a car like butter. When it comes to weapons, snakes have some of the best on earth. Steve goes in search of the adder, the UK's only venomous snake and an endangered species. Then he sets out to blow our minds by showing us the fastest snake on earth: the diamond rattlesnake. By filming it in super-slow motion, we get to see just how impressive it is at catching prey. Then we have the crocodile, one of the planet's ultimate predators. Steve puts it to the test, but this time it's not about its phenomenal bite, it's all about its ability to hold its breath. Steve puts himself through his paces to see how he compares to a crocodile - in the battle of the breath hold, who will be crowned king? And, finally, an animal whose weapon is silent but deadly - the barn owl. They are the ultimate stealth killer, able to completely surprise their unwitting prey - but just how quiet are they? Steve heads to a sound studio to put this to the test, and the results are mind-blowing.
