The black suit may look cool, but it’s a lot more than that. The additional power granted by the symbiote also makes Peter more aggressive. His Great Power now rewards him with an Attack token for defeating Thugs (instead of a Heroic token), and even his Great Responsibility grants him a Wild token for rescuing Civilians (which can be used much more violently than a Heroic token). While Spider-Sense keeps him one step ahead of the Villain, Peter may lose control of himself if he gives in to the hostile nature of the symbiote.
