So, the outcome of this Battle Royale for Gunnar Söderberg personally would definitely depend on the environmental factors. If we're talking a Hunger Games scenario where there's a lot of terrain and stuff, Gunnar might stand a chance. He grew up in the frigid frozen north, and would probably survive pretty well if he could sneak around in the snow and leap out of icy trees to take people out. He also spent some time playing in Florida, so he is okay in humidity and swamplands. And if there were wild animals there amongst the terrain he would probably do pretty well because he is a friend to all creatures and could ask the animals to maul people for him. If it was just an empty arena of weapons and death like in Gladiator, though, Gunnar would probably die pretty quickly because he's been in about five fights in his whole life and it's just not his skill set.
