The Holo Defense API is a security system designed by the Haltmann Works Company. It serves as an antagonist and boss in Kirby: Planet Robobot.


Kirby encounters it in Resolution Road. The Holo Defense API initially does not attack, instead summoning holograms of past bosses Kirby has faced to fight the puffball. However, after all four of its holograms are destroyed, the API begins moving unpredictably around the stage. After Kirby hits it several times, the API will fly violently into several pillars around the area before exploding.

  • The Holo Defense API's crystal-like appearance makes it resemble another boss in the Kirby series, Pix from Kirby 64: The Crystal Shards.
