#093: Haunter
The Gas Pokemon
Ghost/Poison
Height: 5-6 ft tall
Weight: 0-1 lbs
Sound: Sometimes a very mischievous or malicious sounding cackle. Or possibly just a light giggle if you’re inevitably going to become the butt of a practical joke. Normally, you can simply hear a slight hissing sound, mostly because of its composition as poison gas.
Also worth noting that on occasions, all members of the Gastly line are capable of speech. Knowing their composition was once from that of a living being, there's always a chance that they know how to talk. Beware, because talking Haunter can sadly be pretty obnoxious, even compared to other
