Early on in the game these things are your worst nightmare. You see a large amount of water and are low on hydration and go to get a drink, suddenly this guy leaps out of the water and destroys you, basically be cautious about drinking from rivers or a oasis.
This guy is my favourite so far, right from when I first meet him, I was a noob and wandered close to a swamp well he came flying at me missed and disappeared behind me, I'm like what the neck was that, climbed a big arse rock asap and looked around, bugger came bounding back towards me and leapt straight up that rock like it was a mole hill.
Tamed the bugger and took him hunting, came across my first raptor and shat myself thinking oh rap I am screwed, nope Kappa flys over my head, collects the raptor and pile drives it into the ground several meters away, hilarious. Always fun times with Kappa around.
This Dino is often underestimated, yes they’re somewhat weak but in the early stage of the game they can destroy you, their grab attack is VERY useful for killing smaller predators, and for pvp. I suggest taking one if you’re into pvp, make sure to dump a load of points into health and damage, their weight is decent so don’t worry about it
