" To add on to this overpowered SBB, Zeruiah adds all elements to attacks. Zeruiah is currently the only unit capable of attacking and providing all elements into one Brave Burst and the second unit to ever provide all elements by using BB/SBB (first is Shida). This is amazing as units will always deal strong damage against enemies. Only problem is that elemental damage bonuses do not take elemental buffs into consideration."

She's actually third. Second was Nice Burny with Super Bravest Burst.
