Brail

Like the other Combaticons. Brail was once a elite autobot soldier that was apart of the Autobot elite guard until he was fired, now wanting revenge he and his mates joined the Decepticons and taught them to be soldiers.

When it comes to his fellow Combaticons he is considered the most friendly towards Autobots. Sure he has complete hated of the Elite guard but that just it. He still has many ties to other old Autobot friends and doesn't really kill them unless he have to.

He also can combine with his teammates to form Bruticus.

History:

Brail was forged in late Nominus times, he was once an Elite guard member along with his team but he and his team got fired prompting them to join the Decepticons as revenge for them being fired.

During the war he and his team gained the ability to combine into Bruticus during Operation: combination by Banzaitron. During the ensuring battle against the Autobots, Bruticus cornered some Autobots(and Elita team) With Menasor, but was defeated when the enigma created Orthia out of Combining Elita-1's team together[Operation: Combination]

He was one of many soldiers lead by Archforce to combat Megaempress pacifist grope and defeated Megatronia.[Threat of Megaempress] While on a patrol he met the mysterious Sideways, who wanted to meet Megatron for some reason.

After ending up in Polyhex by Sideways, Brail ended up fighting him after he defeated the Polyhex armies, including Megatron himself. He particularly assisted in the fight between him and Optimus, before he had to be save by Astrotrain when Sideways flew into space with him so he could kill him in orbit[Spotlight: Brail]

He was apart of a raid of an Autobot base when he told Skywarp to use his powers to steal the "Super energon" they were after, He did this while fighting an Autobot(possibly elite guard) who felt  as if he was an Autobot traitor[The Pax effect]

He was seen battling during the Siege of Vos, where he first met Blowback who he later married. He was one of many Decepticons to end up on the Nemesis and got stuck on earth. He welcomed back brawl as Payload reintroduced the lost cons to Megatron[Hound and the WW2 transformers] 

He was taken out of his timeline by Vector prime, where he helped the member of the thirteen hunt down and kill sideways, along the ways visiting may universes and even the void before he was returned home by Physis[The Brail Paradox]

When the Nemesis went to Combatron, he was with Megatron when they raided the vaults, however he save Beta Maxx from being killed by other Decepticons[Stellar Oddesey]He saw as Divebomb gave prime a tracker which could find the Allspark[Transformers vengeance 2 of 4]

After the war he and Blowback went on a trip aboard the lost light to escape the brutality of Galva convoy, They had another trip, which ended up with him getting the Rhisling from Atlas so he could kill Exarchon, which he did.

Later he was seen at Lio Convoy’s funeral, where he received a scary vision of Mogahn the mass[The Threefold spark] He formed a group to secretly prepare for Mogahn, and when he finally came he went out to reawaken Atlas and Gaea.

He seemed to be fine that Beta Maxx went with Blowback team rather then his own team [Spotlight: Beta Maxx]During the final battle he unlocked the Powers of the Rhisling, and used it to defeat Mogahn[The end has come...]

Literary a day later he tracked down the stranded Gobots crew, who he decided to help getting home, when Cy-kill tried to restore his universe by destroying Brail one, he and Grax-treds tried to stop another threat, the Hytherion, from eating it[Transformers V Gobots]

He was at his sons wedding along with his family[Revenge of Baron Karza]He was mentioned in "The cosmic Continuum" Baron Karza wrote while he compared him to his counterpart from the Arterial cluster[The Cosmic Continuum]

Notes:

Brail is a OC character made to replace Swindle as part of the combaticons.

He shares his bodytype with Treadrook, Leyland, Roadfire and Rollbar

He's about 10m tall

Brail also has an immortal spark

Brail seems to be the second most high ranking member from the combaticons within Decepticon military command, as he's seen quite often leading battalions without his team members.

He's possible the only cybertronian who has visited the void of creation, as well as possible the only cybertronian within Suleforger continuity about the shrouding event
