Alduin the World Eater ain't playin' around. That dragon's got the power and guard to back it up. With a beefy power score of 40, he could wipe the floor with First Sister Yumi, who’s got a weak power of just 5. Sure, Yumi's got a nifty bag of tricks with her ice powers, but Alduin's got the kind of destructive might that ain't gonna be held back by any of that freezing nonsense. He can call down meteorites from the heavens to rain down chaos and destruction on Yumi, while she's busy skating around trying to get a shot off. Her ice arrows and cold winds won’t hold a candle to Alduin's raw strength and aerial agility. Plus, that unique thu'um of his? That’s like unleashing the fury of the cosmos. When it comes to battles, it’s all about power and ferocity, and Alduin’s got that in spades. In the end, Yumi might freeze herself up nice and pretty, but Alduin would be the one taking the win, just devouring all in his path.
