WHEN MONSTERS ATTACK! On a solo excursion beyond the boundaries of the Cats Lair, Panthro is enjoying the solitude of the wilderness and a brief respite from his responsibilities when he is set upon by a pack of giant, hostile creatures. For a warrior of his nature, this just became the best vacation ever! But as the battle is joined, the true intent behind the attack is revealed and this secret could spell doom for all the Thunderans on Third Earth! Acclaimed ThunderCats: Lost author ED BRISSON joins artist DAVE ACOSTA for an all-out slugfest starring the strongest of the ThunderCats in ThunderCats: Panthro #1 featuring two-fisted covers from ACOSTA, SEBASTIAN PIRIZ, ROBERT QUINN, and WILL ROBSON!
