Since 2012, the comics have said that mysterious machine known as the Boon not only made Ivar and his brothers immortal and enhanced their bodies but also enhanced their mind. The three brothers now have minds with unlimited storage and analytical capacity, as well as perfect recall when necessary. Even if the brain is destroyed and must later regenerate, all memories and knowledge are retained. The Boon also equips the mind with a unique form of apathy, so that emotions do not play a prominent role in their thought processes (although they do still feel them). This makes them immune to depression and other forms of mental illness, allowing them to experience eternity without losing their sanity over time.
