If one wants or needs another designation for a larger than life character I suggest, among other possibilities:

Antaeus, Atlas, Beowulf, Grendal, Colossus, Goliath, Mammoth, Samson, Thor(ston), or Titan.

[PS, I would be patial myself to Beowulf. :) lmk]

Probably edited for spelling, grammer, punctuation, or typos.
