Stantler (the Big Horn pokémon) are another sadly nearly extinct pokémon. Stantler are annually hunted in poaching 'contests' for their illusion-creating horns, although these 'contests' have been banned in nearly every part of the world; some law-escaping criminals avoid these and hunt the Stantler anyway.
It has never really been understood the way Stantler can use their horns to create illusions but I have my own theory: In my theory I believe that, due to the way homo sapiens interpret coloured images, we have a massive gap between what our brains can actually properly 'show' us without, as you may say, 'skipping' or 'cutting corners and what is a true image.
"Doesn't make any sense", you may say, but that's exactly the point... the image that is caused by Stantler quickly shaking its antlers back and forwards doesn't make any sense to the brain and therefore the brain replaces that image with one it sees 'making more sense'. This is why you may see a totally different image and sometimes scary image in place of the shaking antlers. Although some believe that this strange phenomenon is caused by the antlers warping reality in the air that travels through and around the antlers as it shakes them. But what completely baffles me is the fact that this 'antler trick' works on other pokémon with better eyesight than us!
Imagine walking through a calm quiet forest, in the distance you can see a herd of grazing Stantler. Peace seems to fall over you when suddenly gun-blasts seem to burst from everywhere; you look ahead and see the peaceful Stantler are all dead! This is what it is like to be in a forest during a Stantler hunting session. It is absolutely horrible, especially for the Stantler. Usually the hunters only kill and take around three Stantler due to the Stantler's amazing ability of illusion as stated before.
"Not the best fighter", you may say as you see a Stantler. Yes, they may seem dopey and weak but I bet you haven't felt the full force of a Stantler's buck or kick. Amazingly Stantler a very springy muscle compound joining the head and body; this muscle-like tissue stops the head from recoiling after a Stantler bucks it's head, this is why a Stantler's head can continuously buck without recoiling back. A Stantler's eyes may seem very dopey and droopy; making Stantler seems poor sighted. But don't be fooled! This is somewhat of a disguise for predators; in truth, my studies have proven, Stantler have very good eyesight for an animal of their low status in the food-chain. They can detect the slightest muscle twitch or insect scuttle from 100 metres away.
In conclusion, if you want a reliable battler that will always be out to make its owner happy, you should capture a Stantler... although I do ask you; when/if you retire from being a pokémon trainer you should donate your Stantler to a breeding group or a wildlife rehabilitator squad. Remember; pokémon are not toys and can't be replaced when they disappear.
