they say juggernauts' armor is one of the best in the marvel universe, the Ruby of Cyttorak gives its wearer super human strength and an almost indestructible defense. the wearer is almost immune to damages (including physical and mental).
guyver is from another universe, its like an alien that attaches itself to its human host and gives him super speed and strength. with the combination of an alien relic ship, normal guyver's ability is enhanced to gigantic guyver. it gives him ability to fly and move at high speeds, high frequency swords, and my favorite: the giga-smasher! (a pure energy blast coming from the chest).
two alien weapons that gives the wearer super powers.
which do you think will beat the other...
strength and defense vs. strength and offense
