Fenrir

[Yata7]

Straight from the mount's flavor text;

"Following the rise of Ishgard, hoarhounds all but disappeared from the Coerthas highlands. However, the shift in climate caused by the Calamity has seen the legendary beasts descend from their mountain dens once more."

So there you go. Fenrir is a single powerful hoarhound.

Huh, look at that.

Granted it's just a verbal expression of the thing we just did, and the English line "The tales do not do you justice, Warrior of Light." says essentially the same thing: "Hey, wow, I was expecting that thing to maul you to death." For what it's worth, French and German both went with the same expression as English.

I play the game in Japanese and can confirm this with a screenshot.
