User blog comment:ColdGrand/blackbeard's dark-dark fruit is a logia type??/@comment-2244785-20110309035446

The major strength of this particular fruit, the darkness the user turns into that swallows up everything, is also its major weakness. Since the darkness also absorbs attacks, the user of the fruit is still vulnerable to attack, which doesn't pass through the darkness they turn into. If they fail to absorb an attack in time, the user can be hurt like any other normal human being or even more, as stated by Teach. However, like all Logias, the user can still reconstruct their bodies from their own elements.
