Frezidius was also made in a nuclear snow attempt but this was different from Ice Hedorah
Frezidius was made by the second attempt against global warming this one was more stable causing the existence of Frezidius instead of another Ice Hedorah. Frezidius is shy but can lash out when cornered. Frezidius' only weakness is... Torcanos! (A mixture between a volcano and a tornado) To break it down Frezidius is a better version of Ice Hedorah by far.
