If you don't know, Igor is the Head Zombie of the SS64 PvZ Universe named after Frankenstein’s Lab Assistant. If you were wondering Why Igor has this facial expression, Well, he got an allergic reaction when he was a little younger. No other explanation needed. No. Head Zombie and Igor are not related in family sense. His actual name is Issac Gore, Zomboss likes to call him Igor since he watched a lot of Classic Monster Movies. He is also the only sane man, figuratively.
