Well guys, I'm back with another theory! Hopefully it'll be a bit better than my last one. Anyways, today's theory will be about Yu-Gi-Oh. Or rather, it's about Yugi Muto. Now then, onto the actual theory part! I think Yugi is actually stronger than most people think, and I have proof for this theory! The proof is actually the Millennium Puzzle. Throughout the Anime (and the manga), you can see Yugi wearing the Millennium Puzzle. If the Puzzle is actually the same weight as gold, then that would already make it pretty heavy on its own. But, if the Puzzle is actually lighter than gold (since it's technically not made from actual gold), then that wouldn't serve as solid proof. However after a while of wearing the puzzle on its original rope, Yugi switched it out for a heavy duty chain so it would be harder for someone to take. As more evidence, Yugi spends practically the whole Anime wearing the Puzzle, and he doesn't look tired from wearing it at all. So even if the Millennium Puzzle itself is light, the chain he uses for it must be quite heavy on its own. Seeing as how the original Anime has been over for a while, we probably won't get any solid evidence for this theory. But, I have still included a couple pictures of Yugi wearing the Puzzle on both the rope and the chain to help support my theory. I'll also leave Yugi in tact for any fans of him that might see this. Enjoy!

In this picture you can clearly see that the Puzzle is on a rope.

 

 

However, you can see here that he switched it to a chain.
