ScrewAttack loves Nintendo for those who don't know. You guys should convince them to hire me. Lol xD jk but you can if you really want to.
Sonic beat mario in one of the other death battle, but yeah they tend to have a thing for nintendo.
The Shield from Ocarina of Time to now was very durable but it was until Skyward Sword that it was mentioned that Shield cannot be destroyed whatsoever, an example of that would be when walking to Death Mountain as a kid and using your shield to protect you in Ocarina of Time)
