This Virus, This Creature

Can you guess what it is?

The sharp rifts,

The heavy base,

Blasts away the anxiety,

Without leaving a trace,

Its roar gives me confidence,

Rejuvenating my body to full health,

Its thunderous stomps scare the demons away,

I gain its electronic power,

And blast everything in my way,

This Virus spreads quickly,

The Creature, resembles a beast,

It gives everyone it contacts, power,

And won't stop until death has deceased...
