Here's my Lego Hero Factoy Brain Attack MOC, Zack Quickfire XL! Here's a picture of him.
Here is why he had the upgrade:
Hero Factory realises that this great hero could not fight properly against the brains and gives him a proper brain attack upgrade. Now, he has the flame shield from Furno and a more advanced version of Furno's sword. Now, he is able to help the Elemental force fight off a lot of brains!
