Oswald F. Trump

Oswald Fitzgerald Trump, often known simply as 'Ozzy', was a successful businessman and entrepreneur in North America. 
Oswald was an exact genetic match to the Great MAGA King. It is thought this was an effort by Magarra to provide a suitable 'backup' host body, should the MAGA King suffer a horrible accident. Born to Fred Trump and Mary Anne MacLeod Trump in 1946, Oswald was raised in New York, New York, with his four siblings. He took after his father and became a successful businessman, eventually launching the tech startup 'META', which would become the most profitable social media company on Earth. 
The Great META War was named after this social media site (beforehand, it had been known simply as 'the Horrible War'). This was because the residents of Earth took to streaming attacks and battles live over their smartphones, instead of running from the intergalactic warfare in front of them. 
Oswald made billions off of META, and soon bought a considerable (yet undisclosed) share of stock in J.F. Sweets Incorporated, becoming a majority shareholder, and working closely with Geoffrey Eckstein and James Fargo (although Oswald operated behind the scenes, attempting to steer the company away from corrupt and dirty business practices). 
In 40 BB, Oswald moved to Portland Oregon, and built a large mansion there, with a beautiful view of the Iron Dildo. Oswald became involved heavily in the local Baptist Church, and, after a time, retired quietly from public life, electing to donate privately to charities of his choice. 
Oswald never met the Great MAGA King, despite the two sharing so many close associates. It's thought that this was the result of an Employer's nudging, as Oswald complained during his time at J.F. Sweets of being 'steered away by a man in a suit' or 'teleported' randomly out of rooms (presumable to prevent the two Trumps from meeting). 
Oswald's home and city were consumed in the Portlandification of 20 BB, in which the entire area was hellified and vegan substitutes were lost. Oswald mysteriously vanished. Whether this was due to being boiled alive, or him escaping (or being 'relocated'), it was never determined; however, as Portland Oregon still exists, and his twin Brother was technically Immortal, it's entirely possible that Oswald F. Trump still lives.
