Kathril

Kathril, Aspect Warper is a legendary nightmare insect from the plane of Ikoria.

Kathril, a cunning insectile nightmare with powerful shapeshifting abilities, lurks in the peaty marshes of Indatha. It uses the shifting, adaptive tendrils on its body to mimic other creatures and delights in deceiving would-be predators. Many a monster hunter, seeing only a big bug, has ventured after what he thought was easy prey, only to met his end at Kathril's mandibles: the planeswalker Vivien Reid hopes that many more will.

Whether hunter or hunted, Kathril chooses when it is seen.
