When enraged, Necroxorus will fire off beams of light from its tusks. These beams of light are incredibly sharp, and can slice through buildings.

Each slice of Necroxorus's tusks sends out destructive laser beams as strong in power as the tusks themselves. While it becomes pained when without light, it also causes its impurities to harden and form into tough armor that lines its body.

Their sturdy tusks will stay sharp even if used to cut steel beams. Light is apparently the source of its energy.
