Visible Zone

The Visible Zone (ビジブルゾーン) is a rare occurrence in the Mega Man Star Force series that makes usually invisible EM Waves visible to humans due to frequency fluctuations. There is no way to predict when or where a Visible Zone will appear, but it appears to have more chances of occurring when EM Beings go crazy or start fighting each other. Humans are usually surprised by this, the Hertz that explains this phenomenon in Mega Man Star Force 2 mentioning that a human called him a ghost.
