Santa-NK1 is a Hardmode mini-boss that spawns during the Frost Moon event. When below half health, the face and beard of the Santa mask will be torn apart to reveal a rather morbid mechanical skull underneath.
Santa-NK1 has four different attacks, all of which occur independently of each other:
- Santa-NK1's chain gun periodically fires bullets at the player. Its rate of fire increases as its health lowers, going from 3.75/sec (initially) to 7.5/sec when below 25% health.
- Santa-NK1 randomly drops large spiked balls on the ground that deal very high damage (120-150+ with Chlorophyte armor in Classic Mode). These increase in frequency as Santa-NK1 takes damage.
- Santa-NK1 will randomly fire a barrage of missiles which can travel through blocks at a constant rate of 5 per second. These barrages become more common as Santa-NK1's health drops.
- Santa-NK1 will also randomly launch a barrage of presents high into the air which rain down via parachutes, causing contact damage to players. These travel through blocks, and are fired at a constant rate of 6.67 per second. These barrages also become more common as Santa-NK1's health drops.
All of Santa-NK1's attacks either increase their rate of fire or increase their chance of occurring as its health drops, as described above; the specific effects are listed in the following table. Note that these changes happen as Santa-NK1's health passes the listed thresholds, and are not continuous; thus, for example, its chain gun firing rate will be 3.75 bullets/second at 100% health and also at 75% health, but as soon as its health drops below 75%, the rate of fire will increase to 4.29/sec.

- The spiked balls can nearly one-shot players in 大师模式, due to their damage being 480. This is by far the most damage dealt by a single attack in the entire Frost Moon event; it is also stronger than most other bosses' attacks, even dealing higher damage per hit than the Moon Lord's Phantasmal Deathray.
- Santa-NK1 has a higher chance of dropping loot in later waves. See Frost Moon for more details.
- Players should note that his present launcher and rocket barrage attacks are highly inaccurate.
- If you have obtained the Razorpine and Golden Shower then you can hit him with the Golden Shower to lower his defense then fire your Razorpine at him. This is highly effective with Spectre armor with the Spectre Hood as it fully heals you no matter how low you are.
- This seems to be even more effective on the because the Spectre Hood still has its old stats, which increases magic damage, instead of lowering it. 版
- 双足翼龙怒气 is even more effective at lowering Santa-NK1's defense.
- 其英文名字“Santa-NK1”是对 Santa（圣诞）和 Tank（坦克）的混成词“Santank”的玩笑，当此敌怪首次发布时曾经用过这个名字。
- The face and mask may be a reference to the "Terminator" film series, as the Terminator has a metal frame and an outside 'skin'.
- It is one of the only three bosses whose map icon does not change after entering its second phase, the others being the Brain of Cthulhu, and the Queen Slime.
- There is no Pumpkin Moon equivalent to Santa-NK1, unlike the other two Frost Moon bosses (Everscream and Ice Queen), who each have counterparts in the Pumpkin Moon event (Mourning Wood and Pumpking, respectively).
