Transformers: Forged to Fight Wiki

Grindor is a Movie Decepticon Brawler.


Although he's a brawling, close-combat specialist, Grindor lets his missiles do the talking in his helicopter alt mode. Note that he tends to get angry when reminded about the time when Optimus Prime 'probed' his optic sensor.

Grindor is a basic Brawler bot who will deal more damage the more Power the enemy has (and amplified if awakened). Due to his high health and Special Attack denial, he can be used in very long fights. However, he can't gain Melee buffs, though he gains bonuses against anyone with high Power.



Grindor's tough armor, health along with Critical Rate Debuffs makes it hard to take down high-leveled Grindors. Careful evading and endurance should help in defeating him though. Grindor uses his Melee Special 1 often, so dash back from his predictable Special Attacks, then quickly counterattack. If his Sig is awakened and you have a lot of power, make sure to dodge his attacks! They deal a lot of damage, especially through Special II, and Special Attack Denial also is another reason to dodge these things.

He is a very tanky bot health-wise. Instant energy attacks, damage over time and powerful Armor Breakers (even more so when the Armor Break can be permanent) will be your friend, as Grindor has no answer to these.

Even more so when he is on a Security Module, or an Utility Module which grants him more Armor, like the one in Rulers of Kaon, in which he becomes absolutely impervious.

Rulers of Kaon

As stated above, unless you have an anti-armor bot or abilities that bypass defensive buffs like Dark Burns, Grindor becomes near-invincible and cannot be hurt regularly. However, if you have abilities that can get around that, Grindor turns out to be one of the easier fights in Rulers of Kaon. Just prepare for a long fight as Grindor's massive health pool will take a long time to drain.

Strong Match-ups


  • Anyone with power rate buffs will feel the force of Grindor’s perforation damage and before they will know it and they will have their specials disabled.
  • Bots with strong specials like Mixmaster will have no chance at all from using the specials 2 and 3.
  • Hot Rod generates a lot more Power because of his signature ability. Grindor gets stronger the more Power the opponent gets, enabling him to deal a lot of damage.
  • Arcee will be prone to Grindor's Perforation and Crit Rate Debuffs.
  • Kickback’s dinner relies on Critical Hits, and Grindor serves Crit Rate Debuffs.


  • Robot Resource - Defenders gaining a lot of Power through this Module will feel the full force of Grindor's Peforation Damage and he can disable the opponent to use even the special 3 when having full power.

Weak Match-ups


  • Anyone who Armor Breaks and Armor Pierces will put Grindor to sleep easily.
  • Galvatron, Megatronus and Megatron (ROTF) deal pretty strong energy damage, which will ignore Grindor's tough armor.
    • Megatronus in particular also has an Armor Break and gains power very slowly, and Grindor won't be able to make full usage of Peforate. Though he can disable Megatronus' Special Attacks.
  • Dinobot’s particular skillset make him adept at cutting through the armor of this thick-skinned helicopter.
  • Megatron will ensure Grindor never toughens up.
  • Grimlock’s burn debuffs and devastating specials will ignore Grindor’s tough armor.
