The character description is quite humorous paired up with that picture of a cute doggo lol.
In context it's talking about the Star-vaders and their invasion of both Cray and Earth, which are the reason the Liberators exist. They were formed as an emergency group tasked with fending off the invaders.
And considering what they look like...
Yeah, they're pretty scary. Throw a few higher up Star-vaders at an entire army and they'll just shred through them all; not for sheer strength(if anything they're actually pretty weak in terms in physical strength) but their ability to "lock" and completely immobilize entire armies is the scary thing about them.
"A good offense is a good defense" is true and all, but if the enemy can outright cripple your defense and render you helpless... that's not good. The fact they have easily billions of foot soldiers that they can just throw at the enemy, along with their ability to
"Яeverse" enemies they defeat(bringing them to their side until they're defeated again or break free of sheer will, like Beast Deity, Ethics Buster did) doesn't help either. It took the entire combined military strength of Planet Cray just to hold their own against the first wave, let alone the weird dual timeline second wave. It didn't take very long for the main weak point of them to be found though... just find a way to unlock all of your allies and they become very easy to defeat. Blond Ezel did it first, but when Dragon Empire agreed to let loose the Seal Dragons(a group of criminal dragons so deadly they were sealed deep underground with some of the most advanced sealing techniques known on Cray instead of a normal prison), a few of them, with their advanced knowledge of seals far beyond that of an average person, were able to do it with ease. Not all of them though.
But that's enough scary lore, considering now I've kinda cursed the thread. Lmao.
