Transformers: Forged to Fight Wiki

Thundercracker is a Decepticon Brawler.


Often fighting in the shadow of fellow Decepticon Starscream, Thundercracker loves a good battle…but only against a worthy opponent. He hates fighting against humans because it feels like unfair victory rather than true combat, and Decepticons aren’t forged to fight by overpowering the weak.

Thundercracker is a melee and ground combat specialist. He is most effective against Bots who use ground vehicles as their Heavy Attack (ie. Optimus Prime, Wheeljack, Prowl) and especially Bots who apply lots of debuffs, especially damaging debuffs (ie. Scorponok, Drift). If the enemy is a ground vehicle, dashing in while the enemy attempts to use a Heavy Attack deals more damage; well-timed blocks effectively parries a Heavy Attack.

He is the only bot who can’t score a Critical hit (which actually puts him in a good position against Bonecrusher), but he can purify any damaging debuffs (and Backfires and Dazes) with Heavies, making this Purify one of the most powerful in the game. If you're inflicted with a potentially powerful debuff like Venom Backfires (especially over 3 stacks as they can Shock), just use a Heavy and you're good!

The best way to gain Melee Buffs is a Special I. After using it keep on attacking the enemy to keep his Melee Buffs active for long enough.


Don't inflict too many damaging debuffs nor spam Heavies (especially if you're using a Bot with a ground vehicle mode) as you'll only give Thundercracker Melee Damage Buffs (which refresh per Melee Attack he hits!). If he has recently tagged you with a Special I, try to avoid further hits to make his Melee Buffs lapse.

Choose some powerful aerial fighters like Megatronus, Cyclonus, or even Starscream. Thundercracker won't have any attack bonuses against Bots with a flying alternate mode.

Try not to use Heavy Attacks while he's above 15% health - It is to be noted that his Block can't be broken until he is below 15% Health.

Strong Match-ups


  • Thundercracker is one of the most potent counters to Bots with Damaging Debuffs.
  • Drift's many Bleeds will only be Purified and turned into Melee Buffs.
  • Bonecrusher's passive Bleeds rely on enemy Crits to activate, something Thundercracker can't score. Also, any Bleed Bonecrusher inflicts will be Purified and turned into Melee Damage, putting the walking cactus in a... dire situation.
  • Scorponok's powerful Backfire and Daze debuffs will be Purified. No more instant Shocks nor missed Ranged Attacks. (This also goes for Barricade and Jazz, who both have powerful Backfires)
  • In a rare case of a Brawler being superior to a Tactician, Thundercracker has bonuses against Optimus Prime's Bleeds and the fact the Prime is a truck means he will have increased damage.


  • The Harm Accelerator's potentially harmful effects will be Purified when Thundercracker is in his Aerial Alternate Form.
  • Melee Bleed - These Bleeds will only turn into Melee Buffs AND Heavy Attack Burns.

Weak Match-ups


  • Megatron can steal his ally’s melee buffs so Megatron will be the one ascending.
  • Starscream will Nullify his comrade's many Buffs.
  • Galvatron, Megatron (ROTF) and Megatronus all inflict instant energy damage and will blast though Thundercracker like he's nothing and Megatronus in particular has the relic of obedience which means Thundercraker will not gain enough buffs in order to defeat Megatronus.
  • Grimlock’s melee buffs and high special damage will take the brawling jet down.
  • Kickback will T-Clog Thundercracker and disable the Purify, leaving the brawling jet prone to Kickback's diet.
  • Bots with any Unblockable Attacks (ie. Cyclonus, Duped Dinobot, and Duped Mirage) will break through Thundercracker's powerful Block.
  • Meanwhile, Beast Ancestor (Tantrum) makes the attacks of Beast Wars Bots unblockable, so add Beast Purification (Optimus Primal) and Thundercracker will get a taste of his own medicine when his debuffs are purified.
  • The Enforcers Synergy will prevent Thundercracker from Purifying Motormaster, Kickback and Ramjet's many Debuffs.


  • NEVER use this bot against Ly-car-thropy because only Critical Ranged attacks can defeat the opponent.

Recommended Modules

Pair these mods with Thundercracker on your base!

  • The Transwarp Cell will increase the chances Thundercracker will Purify. This is most effective against Raiders whose Bots inflict lots of Damaging Debuffs.
  • The Exo-Filter will enhance Thundercracker's Purify and give him even more Melee Damage Buffs.
  • The Laser Guidance Module will turn Thundercracker's Heavy Attack into a nightmare, especially if he had Damaging Debuffs that were Purified.
  • Strange Refractor allows Thundercracker to stun while blocking, allowing him to deal more damage.
  • Thundercracker is a melee specialist, the E.M.I. Module will keep enemies close to him so that he can keep pounding on the enemy with strong melee damage.
  • The Superconductor 1000 will increase the likelihood of Thundercracker's Melee Gains.


Thundercracker was exclusive to his Challenge Mission, his Crystals and his Arenas. He is the second "Exclusive bot" in the game, the others are Bumblebee and Nemesis Prime.

Outside of these things, he was also obtainable through Nemesis Prime's Crystals and the Generations Crystals (joy!)

Thundercracker Challenge

For two weeks, Thundercracker could be obtained through his challenge.

  • Trouble Brewing, Rising Danger - 2-Star
  • Critical Challenges - 3-Star
  • Thunder Struck - 4-Star

Featured Thundercracker Crystals

On April 11, 2019, Thundercracker crystals appeared in the Energon Store as part of a bundle, then during the Thundercracker Arenas for regular Energon purchase:

  • Stormy Sky Crystal - 3 and 4-Star Thundercracker
  • Aerial Assault Crystal - 4 and 5-Star Thundercracker

Thundercracker Arenas

Starting April 18, 2019, 3-day Thundercracker Arenas had a chance at a 3~5-Star Thundercracker:

  • Aerial Duel (3-Star)
  • Worthy Opponent (4-Star)
  • Superior Combatant (5-Star)

These Arenas are structured like the old Arenas of Featured Bots. That means only 30 grinding Commanders can get these Thundercrackers!

Obtainment as part of Nemesis Prime's Featured Crystals

As part of Nemesis Prime's release, Thundercracker was made available in the Dark Matrix and Doppelganger Crystals for a week starting July 11, 2019, giving Commanders another chance at him (though it's all down to luck!)

General availability

From March 27, 2020, Commanders around the world felt joy as Thundercracker amongst the other two "exclusive" Bots were added to all Bot Crystals.

(For a 5-Star, you need to collect 170,000 Titan Fragments.)



  • He is a repaint of Starscream, in-game and toy-wise.
  • Thundercracker appeared in the background of one of the earliest promotional images for the game.
  • There was an issue where Thundercracker did not purify Burns and Backfires (not Scorponok's Venom Backfires) upon using a Heavy Attack. There was also an issue where Thundercracker would successfully Block Ranged Heavy Attacks from Ground Vehicles. Both of these issues were promptly fixed.
  • Like Starscream, he does not have his handheld gun.
