He has lots of random coughing fits and he also hates taking his medicine despite his terrible condition currently. He’s very direct, but can also be whiny and loud. He tends to also speak in third person saying Zim instead of I, or saying “THAT’S ZIM’S URTH (earth)!” instead of my. He’s also quite short like similar to a child he’s about 3’3 and also very narcissistic and self-entitled. But sometimes he can be a softie even snuggling up to you. He is an alien called irkens.
