Cyclonus

Once, Cyclonus was a great king of the Vector dynasty kingdoms and ruled the area which would become the city-state Vos, but by the modern day however he now just a menial non-important bot who works for the warlord Megatron.

Cyclonus, by himself is extremely loyal to Megatron. As a former ruler himself he acts as an advisor to the young bot(to him) in ruling the Decepticons, having assumingly controlled a kingdom until the Quintessons came to Cybertron.

He the partner of Tailgate, who is his queen.

History:

Cyclonus was forged just before the age of Wraith and ruled the Vector Dynasty along with his queen Tailgate until the Quintessons came and overthrown him with other kings when they took over Cybertron.

When he heard of the Alpha Vanguard resistance he joined them and become good friends with the Warlord Galvawar. He was part of a trio also consisting of Galvawar and Scourge who Nova prime sent to reawaken Trypticon[Quintesson Revolt 2 of 3]

When the Quintesson revolt was won he went into obscurity until he was recruited by the Decepticon Megatron During the Sentinel era. He was one of many Decepticons to be on the ancient warship the Nemesis and got stuck on earth.

He was mentioned along with Tailgate when Banzaitron was talking to Soundwave about his date to Moonheart[Shatter glass concept/ Best body 2 ]Along with Soundwave, Hotrod and Optimus, he was involved into going to Cybertron's core and putting the Omegarus keys in to restore Cybertron[Transformer vengeance 4of4 ]

Notes:

He's a fusion of Armada Cyclonus and IDW 2005 Cyclonus

Tailgate and Cyclonus may have upgrades over the years to keep healthy, because bots that old usually wore down as their components eventually start to break down.
