Echidna (Fire Emblem: The Binding Blade)
The "Hero of the Western Isles", Echidna, from The Binding Blade is like a feminine warrior-woman straight out of an American comic book, which is rare for Fire Emblem. Her main weapon is also an axe, making her an even more rugged character. Her personality is similar to a caring older sister of sorts, but sadly, her Strength isn't very high, which is a little pathetic. You could probably use her if you haven't properly raised a good axe unit, especially because she has high skill and speed, meaning she'll easily land hits. And if she can equip Armads, her weakness in Strength and Defense will be covered, which is definitely useful. Overall, the decision to use her ultimately comes down to personal preference.
