The Spor-o-mega part
The Spor-o-mega is a Spit weapon used to battle Zarkhator in the final battle in Spore Hero. It is different from the other spit weapons in-game in that it resembles a grey bulb with blue crystals sprouting from it, and it is the only creature part in Spore Hero that doesn't come with Spore.
The Spor-o-mega needs to be charged before firing while fighting Zarkhator but when in battle with something other than him it does not require charging, and acts as a normal Spit level four weapon does. The amount of damage the Spor-o-mega does in regular combat is also less than what it does in the battle with Zarkhator.
