Astonishing Tales (1970) 20-A

"The Final Battle!"

Ka-Zar finds himself engaged in battle with an over-confident super-villain who talks way too much, at an A.I.M. castle headquarters.
The presumptuously named Victorius has the Savage Land sovereign at a disadvantage. It falls to S.H.I.E.L.D. agent Bobbi Morse and Ka-Zar's pet sabretooth tiger, Zabu, to save him from an assured death at the hands of the self-made Super-Soldier Victor Conrad has become.
Zabu literally brushes aside the Plunderer in a castle corridor and ignores a nervous, vacillating Gemini. The tiger lunges at Victorious, only to succumb to knockout gas.
Bobbi further distracts Victorius to throw the vial of Super-Soldier serum in Ka-Zar's direction. Playing the noble savage, he refuses to use it to enhance his strength and endurance - preferring to beat Victorius with his own natural fighting prowess.

Final issue featuring Ka-Zar and the conclusion of the "Savage in the City" storyline.
