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 (if duped). Due to his high health, he can be used in very long fights. However, he can't gain Melee buffs.


Grindor's tough armor 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.

He is a very tanky bot health-wise in the game (in a way), so instant energy attacks will be your friend.

Strong Match-upsEdit

  • 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.

Weak Match-upsEdit

  • Anyone who Armor Breaks and Armor Pierces.
  • Galvatron, Megatronus and Megatron (ROTF) deal pretty strong energy damage, which will ignore Grindor's tough armor.
  • Dinobot’s particular skillset make him adept at cutting through the armor of this thick-skinned helicopter.
  • Megatron will ensure Grindor never toughens up.

Trivia Edit

  • His vehicle mode is a modified Sikorsky CH-53E Super Stallion Helicopter.
