An ogre-like being, Heat Miser's mansion is a volcano. He comes from Southtown, USA and has a brother named The Snow Miser. His voice actor is George S. Irving. George was originally on Underdog. It explains why unlike Snow Miser, he touches anything and it melts. Heat Miser becomes powerful to audiences of his movie, The Year Without a Santa Claus from 1974. He also, was in a Miser Brothers Christmas, where we are introduced to Tinsel, Bob and North Wind. He sings a ragtime song, that goes like this:
Lyrics of his song
I'm Mr. Green Christmas, I'm Mr. Sun, I'm Mr. Heat Blister, I'm Mr. 101, They call me Heat Miser, whatever I'll touch starts to melt in my clutch, I'm too much!
(Yet to come)
How he is not like Snowmiser
Mister Heat Miser and Mister Snow Miser (or Cold or Freeze and Hot) are liking their Christmasses warm and frozen. One wants it white and Heat Miser wants it green.
