Sigma – Overwatch

It is not long now until Sigma, the newly unveiled hero reaches the live Overwatch client. Due to an experiment gone horribly wrong, Sigma has become a volatile tank that can take flight, manipulating the gravity that surrounds him. Providing him with the capabilities of overseeing and protecting his allies.

We take a closer look at the eccentric astrophysicist Dr Siebren de Kuiper visuals, skills and his story of how he has become the hero known as Sigma.

Dr Siebren de Kuiper aka Sigma

After spending most of his years devising a way to harness the power of gravity, Dr Siebren de Kuiper performed an experiment on the international space station. Believing it will bring him a step closer to a breakthrough of his research. However, Dr Siebren de Kuiper was exposed to a mysterious power from a black hole he inadvertently created, causing psychological damage.

Shortly afterwards, the eccentric astrophysicist noticed he was able to control the gravitational forces at will. Once he landed back down to Earth from his failed experiment on the International Space Station, the government stepped in and took Dr Siebren to a secret facility where was quarantined and studied upon.

The project Code name was “Subject Sigma.”

After many years of being locked in isolation studying “Sigma” unique powers, the facility was broken into by evil crime syndicate Talon. He offered Dr Siebren to join his team unaware of Talon true motives.

Sigma has now honed his skills and has become a deadly weapon for the syndicate.
