gizmos background:  
gizmo grew up with three older siblings, an asexual lezbian scientist sister, a bisexual moocher bother, and a crossing dressing collage brother who he adored and two moms. he grew up in a very queer environment, and this did aid him in later years. he often had to spend the night at the collage dorms with his brother when his mothers were out of town. here he like to dress up in dresses and armor and play fantasy with his brother and friends.  
he did like to dress up as a princess but he wanted to play as a prince or a knight or the dragon more, his brother pointed it out and gizmo realized came to realize he was trans and identified as male rather than the female sex he was given.
 
later years he was a co owner of a company were he designed machines with his sexual partner filthy rich.  
it was succesful and gizmos life was becoming complete when he met the beautiful mare rarity who shared his love for the fine mechanical works
