antibody
An antibody is the self-appointed knight order of the immune system, indiscriminately attacking any protein it deems suspicious. It doubles as a morale-boosting performer, fully inspired by the oratory of vaccines. Typically hidden in the shadows, it hosts a frenzied allergy spectacle when it overreacts. Eternally torn between self-defense and self-attack, it embodies a dual personality. Permanently teetering on the knifeās edge between poison and cure, it bestows both reassurance and dread upon its host.
