benefits

SCP-021 does confer some benefits to its host. The tattoo has been proven to accelerate the release and re-uptake of epinephrine and decrease lactic acid buildup, providing boosts of strength, confidence, and pain tolerance in stressful situations and reducing the usual after-effects of weakness and fatigue. In addition, the tattoo seems to have some beneficial effect on the host's immune system. Aggression profiles in hosts are generally higher than average, though whether this is a direct effect of the tattoo or simply a reaction to the constant pain remains to be seen.
