Negative energy seemed to have two dimensions of abilities. The first ability was abstract, reversing moral concepts.
The second dimension of the ability was more absurd, as it could grant Martin superpowers in comics and various Marvel settings. He could even release energy waves or transform them into cold weapons, and he could even share these abilities with his subordinates.
However, when this energy was completely transferred to others, it became less absurd. The energy would heal the new possessor but might not retain its original power.
Of course, in Lille, perhaps because Martin and his negative energy in this world had not yet become so powerful.
Lille could clearly feel his mind becoming clearer. This feeling was akin to the first time he used the Lizard Serum, when the activity of his brain cells initially increased.
