The Graviton item is a power-up in de Blob 2. When collected, Blob is transformed into a sort of black hole that sucks in enemies and certain items. It's also what powered the Hypno Ray when Blob defeats Comrade Black and overloads the machine with colour; thereby overloading the powerup and causing it to go out of control.
With a Graviton power-up, fighting isn't really required. Just roll up to enemies and they'll be sucked into you and lost.
It may be good, but like all power-ups cannot be sustained for too long. Don't grab it unless you know you can make it count.
The Graviton power-up isn't seen much in the game, as it only appears in one or two levels.
Ability[]
Slam a Graviton to transform Blob into a black hole that pulls in all enemies within a short distance. For example, if you're in a tight spot with little to no room to dodge attacks and hardly any paint points, you can slam a Graviton to charge through. A Regen power-up could also do the trick, but there may not be one close by.
