This stallion is bittersweet for me since as wonderful as he is in his own right, it was this fusion that ultimately resulted in the loss of RT’s love Spicy Cider as he fused with Royal minutes to become King Righteous Authority as shown here.  
Thankfully the 4 component boys were able to put their heads together to create an exact copy of Spicy Cider so he may live independently once and Tashie would be reunited with her one true love.
 
Anyway biases aside XD
 
King Righteous Authority is a very worthy ruler standing proudly alongside his wife and a good friend of RT’s Queen Fresh Care. How the two look at eachother when giving town speeches or hosting announcements says it all with no words needed; a love just as fierce as the other royal couple King Speedy and her majesty Queen Galaxia, the two are certainly an unstoppable pair making up for each-others weaknesses and playing off each other’s strengths. Righteous always holds an air of relatability making him very approachable among his subjects despite his proud stature and incredibly regal looks. He grabs the respect of everypony around meaning disagreements that break out in the plaza are quickly subsided by one look at those impressive flanks approaching them.
