Reader Nathan asks: "Do you think we'll ever be able to build robot mecha like the Gundams from the Japanese anime series Gundam or the Valkyries from the Japanese anime series Macross?"

So to comment on what Warscythe and bigwilly262 said. The gundams where made of something called gundanium. It was lighter than any other alloy and about 1000 times stronger. Tanks couldn't even touch them. And I think there were so bigg because there only competition were other gundams. They had to carry huge weapons around like the beam rifle pictures above and a huge heat sabre (sword). And it didn't matter how big of a target they where because of there armor. They also travel great distances very fast due to there size.
