This just happens to be my first AR fic in any form, so please don't hurt my feelings. Oh and I don't own Young Justice, Teen Titans, or Alex Rider. I wish I did though…
The two boys, at first, looked exactly alike. Both were blond, had blue eyes, and had the exact same facial structure. Even as they grew older they didn't change, and very few could tell them apart. But after the two turned fourteen, something other than their appearance changed. One was always missing or sick, the other was always falling asleep or seemed too tired to do much of anything.
Neither was ever around when something big happened. Like that time London was being held hostage by a super villain and one of the two went missing and then showed up after everything was over.
Their names were Jonathan Alexander Rider and his twin (younger) brother Ian Thomas Rider. The sons of the great Alexander John Rider, who had gone missing seven years prior to where we begin this narration. He disappeared while on a 'business trip' for the 'bank' he worked at.
Since then, his sons had been taken care of and (at Alex's request in his will) trained (secretly and unknowingly) by their surrogate Uncle Ben and his wife Jack. As the two boys grew and changed, so did their bond.
One boy, John, was recruited by MI6 at age fourteen. The new head (Mrs. Jones), had given John a choice- accept or we ask your brother. If he says no then we'll go find another person to help up with their not so little problems. John and Ian were too alike and John knew that Ian wouldn't say no to MI6. To save his brother, the elder boy became a spy. The other boy, Ian, became something quite a bit different.
Ian became a superhero.
Unknown to the two boys, their mother (who had died giving birth to them) had been a Meta Human. Her powers had included the ability to take normal human attributes and enhance them into something completely superhuman. Speed, stealth, strength, psychic abilities, and coordination became deadly weapons in her possession.
Her sons inherited this power.
The two boys soon became widely known in their positions of choice. John was whispered about as Agent Devil, the Destroyer's son. Some even went as far as to call him Alex Rider when they dealt with John. This highly pissed him off.
Ian became Angelicon, one of NightWing's four protégées. Every night he used a hidden Zeta tube in London to meet up with his friends and go on patrol in Gotham. The criminals that met him became terrified of his shadow and would flinch at the very mention of Angelicon.
This story picks up just after John and Ian turn sixteen, as some rather unsettling news reaches the Justice League's and MI6's ears…
