History
Thor was an alien who disguised himself as a primitive human and allowed himself to be frozen in ice and discovered by humans. He was discovered by Joe Bolton and transported to the USA. He was moved to cold storage and was accidentally thawed out when a fire broke out. He went on a rampage, escaping into a nearby park. Bolton followed and fell into a frozen lake. Thor and his crew retrieved Bolton's frozen body and took him back to Jupiter as an example of a human specimen.[1]
