A team that could not die?
That sounded like figment of fantasy. Death was an inevitable end for every living being. No matter how avoided, this circle of life was never in continuity, rather it's movement edged towards an end where life ceased to flow. Nevertheless, it can not be denied that that clutches of death had some how been defeated by some beings, but in such grounds, the rarity of this happening was spontaneous. Self-generated not by speech, nor mere actions, the occurrence of immortality was a chain reaction triggered by a desperate alterations of one's mortality.
When immortality was reached, even the existence of time is defeated. As not even time was able to leave a mark on that which could not age.
