Foulspawn
From Lexicanum
Foulspawn was one of the most diseased and disgusting of all Nurgle's Champions. It was said that the sight of him was so horrifying that hardened warriors who saw him were rendered incapable of any action while they gagged and wretched in disgust. Nurgle was deeply fond of his unsightly Champion, and eventually blessed him with the reward of Spawndom. Many Chaos Spawn die within minutes or hours of their transformation, being killed by their former followers, slain in battle or expiring as their impossibly mutated bodies give out under the strain. Such was not the fate of Foulspawn, however. He not only survived, he grew and prospered. By some strange quirk of fate (or equally strange whim of Nurgle) Foulspawn was able to survive by ingesting and absorbing the fleshy tissues and bodily fluids of living creatures, which he achieves by grabbing his victim with his sticky, toad-like tongue, and then swallowing the still living creature whole.1 2
