Tower Defense X Bosses, Ranked

Bosses are the final enemy that you will battle in each game mode, and they are all different. Some are immune to certain attacks, and others have weaknesses you can target. Bosses placed in S-tier mean they are the strongest and most powerful, and D-tier are the weakest and easiest to beat.

S-tier Bosses

  • Eradicator MK | Custom - The Eradicator MK | Custom is one of the strongest bosses to face. It has an Annihilation Sweep ability, which allows it to kill a group of targets quickly. If it enters its Energized Fury phase, it can heal all of its Shield and Health back to the maximum.

A-tier Bosses

  • Eradicator MK II - The Eradicator MK II has two 6 barrelled rotary medium machine guns attached onto each of its arms as well as two 2x2 rocket pods on the shoulders, and a 1x2 on each leg. It has a 50% resistance to fire, and a 30% resistance to explosives. Its attacks deal high damage, so make sure you come equipped with the right skills that can counter its fire and explosive resistance. (Using Warship is the best way to counter the attacks; having a Bottom Path Railgunner tower will be the best chance of defence.)

B-tier Bosses

  • Eradicator - The Eradicator uses a 12-Shot Burst Attack and a 3 Shot Rocket Burst Attack. The 12-Shot attack can be dodged by placing cheap towers around the Eradicator, making it shoot them instead. A great tip to remember is that the Eradicator can be frozen, and Patrol Boats can be used to overwhelm it. With the right skill and timing, this boss can be beaten quickly.

C-tier Bosses

  • Exo Santa - Exo Santa has a very high HP pool but its damage output is low. You can use missile Troopers to take it down quickly (although not cost effectively) or you can use Laser Gunners, Railgunners, or Juggernauts.
  • Nightmare Exo Santa - Nightmare Exo Santa has a high HP and a low damage output. It uses a Festive Spray to deal damage but it has a very long cooldown period. By repeatedly using Juggernauts, Railgunners, or Laser Gunners; you can take it down quickly.
  • Revived Plague Doctor - The Revived Plague Doctor has a lot of health but it is still an easy boss to battle. You can freeze this boss by 20+ through using Cryo Blasters, and you can counter its explosive and bullet resistances by using Juggernaut and Laser Runner.

D-tier Bosses

  • Super Revived Toilet John MK I9X - The Super Revived Toilet John MK I9X is one of the slowest moving bosses you will face. Although it can spawn Eradicators to stun your towers, the Super Revived Toilet John MK I9X can be easily stopped by using quick moves and high damage skills.
  • Plague Doctor - The Plague Doctor moves slowly in comparison to other bosses. It can be frozen by using a Cryo Blaster, and it can be slowed down (even more) by placing expensive towers in its way, as it takes longer to destroy them.
