Serenity smiled down at the little girl who had brought flowers to her. It was a charming custom of the planet for a child to welcome dignatries to the planet and after careful scanning by a small army of techpriests it had been agreed that flowers and child were safe.
"They're lovely," she assured the little girl who seemed just a little intimidated by the hulking Space Marines who were 'reinforcing' her bodyguard of Custodes. The exact Legion that provided the force varied on a complex rota system that she had never quite grasped, possibly because none of her brothers seemed willing to explain it. She would have suspected Horus if it wasn't for the disproportionate representation of the Iron Warriors.
Actually, she suspected Horus anyway.
Serenity hugged the little girl around the shoulders, "Don't mind them," she stage-whispered. "They're just here to look after everyone."
"Weally?" And she lisped! The Anima was strongly tempted to take the girl home with her, but father had drawn that line firmly. Kittens and bunnies, yes. Human children, no. Poo.
"Oh yes." Serenity gestured with one hand, a complex code that detailed in this case exactly which part of her travelling luggage should be brought out. "They're like big brothers. Do you have a big brother?"
"Uh-huh."
"And does he protect you from bad things?"
The girl frowned in concentration. "I don't think he does."
"I'm sure he does really." The bag had arrived and been unzipped so Serenity reached inside and pulled out one of the two dozen plushies inside. They'd been a gift from someone or other who wanted to curry favour (mmm, curry) stuffed dolls decorated like all her known brothers, her father and prominent members of the Imperial Court. Most probably the person giving the dolls had incorrectly guessed her age. This one was wearing the white and blue armour of the XII Legion and carrying two swords. "Here, this is one of my brothers. His name's Angron and he protects me from bad things all the time. If I had any creepy monsters under my bed... do you ever have monsters under your bed?"
The little girl nodded, eyes wide.
"Well, if any of them tried to get me, he'd smack them good!" Serenity waved the plushie aggressively and then placed the stuffed toy in the girl's arms. "Here, why don't you keep him. That way he can help your brother if he ever has trouble."
A week later stuffed Primarch Angron dolls were the number one gift for little girls in that sector. By the end of the year, the craze had spread to half the planets in the segmentum. Three years later it had reached the other side of the galaxy. A few even reached Eldar Craftworlds although only as items for study and they hardly ever fell into the hands of impressionable Eldar children.

AN: And so, Angron becomes the hero of little girls across the galaxy...
