Premise
In a far distant year, the Earth was attacked by an advanced AI called the Megaspider, sent from a galaxy lightyears away to conquer the Earth. When conventional weapons proved ineffective, the world's nations were forced to come together to find a solution. Their first thought was to build their own machines to fight the Megaspider directly, but nothing they built could even scratch it. Eventually, all they had left and all they could afford was a dragonfly mech and a scorpion mech. All the world's nations could do was pray for a miracle. Then, a lone scientist discovered an amazing power source hidden in the deepest depths of the ocean. This strange energy turned out to be exactly what was needed to turn the tide. However, this also prompted the Megaspider to begin building an army. Will these Megabug Gladiators and their pilots be enough, or will the Earth fall to the mechanical menace?
