Yesnt. While we are by far the most Powerful Guardian in the solar system, there are beings and organizations that we would be hard pressed to try and defeat. The Vex still haven’t revealed the entirety of their strength and force, and with beings like Panoptese, the Undying Mind, and Atheon, it’s clear that they could pose by far the biggest threat to us should we finally face their full power. Then there is of course the Echos. While we may be directly more powerful than an Exho, the Echos grant powers that would otherwise bypass our own power. Like when Maya Sundaresh controlled the Player Guardian. Sure, we could break out eventually, but that doesn’t change the fact that we were controlled. In a Direct confrontation though, very few being could hope to fight us. We are more powerful than Savathune, and while Xivu still has her War Powers and ability to grow in strength due to it, she is now Mortal meaning if we end the fight fast enough, she has no time to grow stronger than us. Of course, there is also the Traveler, but that bugger is on our side. Even if it did take our Light away, we still have the Darkness.
