I'm pretty sure Auron is not the only one in the world of spira who tried killing her before, but what was different when Tidus and Crew DID kill her? Just because there were more of them? So a room full of guys COULD HAVE out muscled her at any time? Sphere Grids and Levels don't actually exist, they ARE warriors and fighters but not much more than anyone else. Afterall we have a jackass with a blitzball as one of us

Honestly... Auron probably WAS the only one who tried to kill her...

He is called the Legendary guardian because he SURVIVED the pilgrimage. We see the other High Summoners (and Seymour) in Zanarkand dome. There is only one we don't see.

They all had one person with them. Not including the 2 Yunas there have only been 4 High Summoners. Seymour made it there as well, and then almost assuredly Belgamine. That's only 8 groups that ever made it to the Dome. Maybe some others beside Belgamine lost to Sin with the final Aeon, but even so that means they aren't coming back to kill her. That's means there is only ONE other group that potentially could have been more than 2 people. If that group either had 2 or the survivors didn't try to attack Yunalesca, then with assurance Auron is the only one to ever attack her.

As for why we could win.

In canon there were 7 there.

One guy is dead so hard to kill, one is an Aeon himself so harder to kill, then the crazy physical power of a Ronso and magic power of an all time Black Mage. Finally Yuna herself was a brilliant summoner. And that's probably why she lost in canon. Yunalesca could not beat the might of the Aeons.
