Personality/Bio:
 
Blueberry Curls was married, rather young, with the wonderbolt Silver Zoom. From this love was born a little pegasus, Cloudy Daze. However, Blueberry Curls soon discovered that her husband had another life with the bourgeois Lyrica Lilac, who had given birth to a little girl, the same year as Cloudy Daze, named Silver Spoon. À la révélation de cette double vie, Blueberry Curls partira dans la nuit avec Cloudy Daze et s’installera à Canterlot. Arrivée là-bas, elle se trouvera très vite un travail auprès de la célèbre Sapphir Shores et rencontrera son garde du corps, Lockdown.
 
A few years later, they settled together, and Lockdown raised Cloudy Daze as his own son. He never liked spending time with his father, who disgusted him with wonderbolts and celebrity. Unfortunately, he was quickly noticed, for his flying speed and aerial acrobatics. However, he refused to join the elite and entered the school of pegasus managing the weather, and graduated as a cloud hunter.
 
Relationships:
 
The relationship with his mother, Blueberry Curls, is a classic mother-son relationship. She educates him in such a way that he does not end up like his father and that he has better respect for other ponies and himself.
 
With his father, Silver Zoom, the relationship is more complicated. Until his majority, he had to spend some weekends at home, with the only thought of going back to his mother. His father doesn’t care about him and prefers to talk about his career.
 
Cloudy Daze hates his half-sister Silver Spoon, who always looks down on him, being more fortunate than him. She likes to demean him and remind him that her father lives with her and not with him.
 
Her mother-in-law, Lyrica Lilac, does everything to have her son-in-law in her pocket. She likes to be appreciated by everyone, and doesn’t understand why Cloudy Daze hates it.
 
Lockdown was the best father for Cloudy Daze. He loved her, and protected her as his own son. Moreover, Blueberry Curls is happy with him, which makes him appreciate his father-in-law even more.
 
His best friend is Pound Cake, whom he met during his years in flight camps. They see each other quite often in Ponyville, and his friend’s sister does not leave him indifferent.
