Heimdall is one of the secondary protagonists in the Mighty Thor series as his comic book debut was in Journey into Mystery #85 in October of 1962. Heimdall is a noble loyal warrior of Asgard and is the brother of Sif and he is mainly known as the guardian of the Rainbow Bridge to Asgard known as Bifrost. While Heimdall is a skilled and strong warrior the reason why he is the guard of the Bifrost bridge is that he has exceptional hearing and vision in which he can spot invading armies coming in from several miles away. However Heimdall normally has to stay at the bridge at all times (and has only occasionally been allowed to go anywhere else) as Heimdall uses a horn known as the Gjallerhorn to alert Asgardians when their realm is in danger.
