Not to be confused with the "Beast Wars 2" Cyclonus I will upload, they're technically different series X3

Alt Mode: Quetzalcoatlus
Voice: Jason Momoa
Backstory:
The Predacon council selected one of their strongest, most loyal warriors for a mission of importance. A relic of unknown purpose and power to be taken far away from Cybertron and kept out of prying hands.

Cyclonus was selected for this task and given a heavily guarded temple and a transwarp drive set at ‘random’ and sent on his way.

Cyclonus came to Earth a while before Megatron or Primal having already set up a secure base before they crashed.
He stayed away from them, the less they knew about the relic the better.

He was disgruntled when one of the ‘new guys’ continued to try and build a base near his, continually missing his “leave” message whenever he destroyed the shack.
One day he found the perpetrator, a pink Carnotaurus.
Yelling to the thief he transformed and launched an attack on the intruder!.

He was a well-trained warrior, they on the other hand, fought with a brutal, feral rage that cost Cyclonus an arm. However, before Cyclonus could come up with a plan to counter the sheer bruteforce of his enemy, they collapsed, unable to continue.
Scanning them as a Predacon, Cyclonus sighed.
Honor bound him to ensure no Predacon would die a glory-less, honor-less death.
So he collected his arm, and collected this Predacon and left for home.

At the base the Predacon was force-transformed and re-energised.

When they awoke Cyclonus gave them a simple curt introduction.
He was Cyclonus and he was here to protect a relic and he was not welcome to stay for too long and endanger his mission.

Unfortunately for Cyclonus, Galvatron, as he introduced himself, seemed to think that this was now his home even going as far to state as “You owe me a place to stay after destroying mine so many times”, Cyclonus was furious and tried his best to force him out many times. It was not to be as Galvatron always found his way back in and somehow integrated himself as part of the ship’s crew.

Cyclonus gradually found he was reaping some benefit to the new lodger, he knew how to fix things with minimal supplies and didn’t pry too much into his job there.
Yet he came back to the base with injuries 95% of the time and Cyclonus would be lying if he said his curiosity wasn’t raised.

Galvatron ranted for a long time about Megatron and how bad he was, about his abandonment and mistreatment. Cyclonus wasn’t quite prepared for such a info-flood but once more felt compelled to go further into the situation surrounding them.

Investigating the Predacon base he observed their numbers, he recognised them, two at least he’d scared the red flier away once before and they had returned with the purple one claiming to have seen a monster. He’d scared them both away with a threat display but was unaware they were of any significance and still did not see anything of importance with them.

The Maximal base however was a different… He knew that face… He knew that snarl.

Unlike his stealth at the Predacon base Cyclonus let free at the Maximals charging to them with reckless abandon!
“DIIINOOOOBOOOOOOOOT!” He howled, charging the raptor off their somewhat startled feet.

It was a tense confusing few minutes.
For one who valued loyalty and honor so much seeing a friend with Maximals was confusing and upsetting to say the least.
But, as a close friend from way back he gave him the benefit of the doubt.

He heard about the mission here, he heard about Megatron, about how the fool was going strange and rather power-mad.
Galvatron was beginning to make more sense now.

Accepting and honoring his friends choice, Cyclonus promised not to harm his allies even if they came close to his temple, although he denied an offer from Primal to join them.

Cyclonus still made frequent visits to their base however. All to visit Dinobot the two being able to talk about Predacon honor and values easily, sparring and trading insults with Rattrap as they chased the rodent.

With words from a friend ringing true Cyclonus was more open to Galvatron now too, he fully accepted him in his home and let him move about freely (still not to the relic chamber however, honor bound not to). It was surprising for Galvatron, but not unwelcome and his attitude improved a lot at the acceptance.

Life was improving for Cyclonus and his friends! Yet he could feel something bad about to happen, he fretted and feared when a strange object appeared in the sky and found himself genuinely distressed when Galvatron did not return. Unable to leave Cyclonus fearfully hunkered down in his base hoping that Galvatron and his friend Dinobot would be safe.

He was overjoyed when soon after Galvatron returned!
Less so to see he had returned with two others, one being that nuisance of a red flier.

He only allowed them to stay if Galvatron watched them and kept them away from his business.

Skorponok was easy enough to handle, sad at the seeming abandonment from his former crew but glad to be alive.
Terrorsaur was a pain however and despite being fearful of Cyclonus still tried many times to “challenge the monster” and fight him and get the power of his relic.
He lost every time and ever so slowly backed off as Galvatron also fought him into place.

Life continued as it had been before the strange alien weapon appeared. Until it all changed one day.

While on a routine patrol Cyclonus caught sight of something at the Maximal base.
Or more accurately he caught sight of a corpse.

He stared at it.
For a long time.
His processor… Denied it… Refused it…
But it was true.

Rage and pain tore through his Spark and Cyclonus launched himself at the Maximal base, he wasn’t even sure if he said anything, or if it was all screaming rage.
He must’ve said something as they babbled to him as they tried to fight back, to suppress him.
“We didn’t kill him”
“He died saving the future”
“This isn’t the way to remember him!”

Unable to continue facing them Cyclonus fled, still howling to the night, grief-filled pleas to a sky that didn’t budge.

He walked back to the base, full of devastating emotions.
What kind of warrior… no, what kind of friend did not back their friend in a fight?
Energon seeped into his systems and began draining him but he didn’t care.
He didn’t want to care about anything right now.

He collapsed near his base and someone must have found him as when he awoke he was back in his room.

Still didn’t care.

He glared at the wall for days barely moving or consuming fuel until Galvatron angrily confronting him.
Galvatron hadn’t expected Cyclonus to have such a breakdown.

It took days for him to grieve, the knowledge that Dinobot would’ve told him he was being stupid somehow just making him feel worse.
Slowly but surely, he quietly found himself recovering and calming down.

The relic wasn’t the only thing to protect here, if someone he had admired and befriended for so long thought the world was worth it, then he would protect it too.

Still won’t join the Maximals though.

Personality:
Cyclonus is loyal and obedient to a fault.
He has his mission and he will stick to it no matter the problems or disasters that may come his way. It makes him easily close-minded, standoffish, unrelenting and a stickler for honor.

So when things can't be controlled he gets very flustered and confused, often trying to ignore the problem in hopes it'll go away, or try and intimidate the issue away.
If that doesn't work he ends up just kind of accepting it and working his life to refit the new status quo.
He shows a softer chattier side to those whom he trusts.

Notes/Extra:

• Lives in a cave behind a waterfall with Galvatron, then later Skorponok and Terrorsaur.
• Knew Dinobot back on Cybertron and was friends with him for a long time there.
• Wields a staff with a Falx blade on each end.
• Not sure how he’d react to Dinobot 2 or if he’s met them but would most likely be furious at the ‘insult’ to his friends memory.
• They were already getting a bit ‘close’ but after sharing more emotions after his friends death that’s what really got Galvatron and Cyclonus together as a couple as they supported each other.
