Got to say, shadowgear6335 managed to create an awesome theme of bytes. As he showed the Hardrive, it inspired me to try a Byte combiner. Although the combiner failed, I decided to go on to build what I planned the combination to be: A Firewall. Credit for shadowgear for the inspiration.
Firewall is an Exabit combination, similar to Hardrive, which bypasses the evolution of Exabytes, for advanced defense against system invaders.
They are formed only if there's a necessary need for advanced defence, when Exabytes can't hold off the invader.
When they're formed and the threat is over, they start patrolling around the system, to protect the database from whatever danger there is.
Although they are slow, their stretching arms and large size help them block almost any threat.
Their function is simple, so it is possible that the Firewalls sometimes make mistakes and block a wrong target. (I wish I'd had a byte here to show a practical image :D)
Firewalls do not have any weaponry. Their defending is completely based around their shields and brute strength.
This is pretty good, and cool idea. You might be pleased to know that I am also making a byte creation like that of shadowgear. Its theme is, well, if shadowgear made protective bytes, what were they fighting against? You will soon see.....
