Terrance and Henry brothers AU except Henry has been masterminding Terrance’s tyranny reign so that they both can take the Toppat Clan for themselves
If Terrence was a wolf in wolves clothing, then Henry was the wolf in sheep's clothing. Terrence and Henry found out young that together, they could find an equal balance to their timeline powers. And with that knowledge, the two of them easily rose through the Toppat ranks.
And soon Terrence was second in command with Henry his right hand man. Terrence just needed to get rid of two people, Sir Wilford IV the current leader and Reginald Copperbottom one of the most dangerous minds on the Airship.
Getting rid of Wilford was easy, a raid goes absolutely wrong and uh oh spaghetti ohs, no more Wilford. Reginald was the hardest to figure out. And then Henry got a devilish idea.
Reginald kept screaming that he didn't know where all the Government stuff came from in his room. But the Toppats don't deal kindly with Government dogs. All that could be said was what was left of Reginald was thrown into the incinerator as the humane option and that the silent one called Right was a deadly force of Toppat loyalty.
Terrence continued to lead the clan for many years, with Henry preferring to stay in the low light as second in command. But then something happened. A strange energy started seeping out of Terrence, making it dangerous for even Henry to get near.
Henry tried to use his timeline powers to try to go back to a few days ago, but he found it didn't work. And when Terrence tried to forcibly tap into his and Henry's powers, a bright light engulfed both men.
Terrence and Henry were wiped from time and space. The actions they had caused still happened, but the two now no longer existed.
Right became leader of the Toppat clan, his loyalty and brains bringing the clan into an era if peace, ending the Tyrannical Terrence's long reign.
