He appears in Savage of the Sword #36, Conan the Barbarian #112 and #115 I believe.
Hey Xai! Welcome to the forum. Biblically, the Anakim were a tribe of giants living near Gath, in Philistia. They were possibly (somehow) descendants of antediluvian giants. They were the Rephaim, or, the "descendants of Repha". Besides Goliath, there were Ishbi-benob, Lahmi and Sippai. What story does Othbaal appear in?
This is my source.
Thanks for your reply
