Stryfe was created in 1990.

How Darth Stryfe died is still unknown but it's been revealed that his death was on Coruscant in 138 ABY (138 years after the Battle of Yavin in the first film)

Philip Summers (grandfather), Deborah Summers (grandmother), Christopher Summers (Corsair, father, deceased), Katherine Anne Summers (mother, deceased), Alexander Summers (Havok, brother), Gabriel Summers (Vulcan, brother), Jack Winters (Jack O'Diamonds, former foster father), Jean Grey-Summers (Phoenix, wife), Madelyne Pryor-Summers (ex-wife, deceased), Nathan Christopher Summers (Cable, son), John Grey (father-in-law, deceased), Elaine Grey (mother-in-law, deceased), Sarah Grey-Bailey (sister-in-law, deceased), Aliya Jenskot (daughter-in-law, deceased), Tyler Dayspring (Genesis, grandson, deceased), Stryfe (clone son, deceased)

I think the Nerf N-Striike Elite Retaliator is good, because it uses the clip system, which is the system you are most likely going to use. Also, the gun is shoot-prime-shoot, or single-shot, so they don't have to deal with holding the flywheel trigger for a second before firing. :-} But, this gun does NOT have slam fire, but it comes with a barrel, stock, and foregrip, so basicly you are giving them the essentials to Nerf! Plus, it has a handy primer indicator which turns orange when primed. If you want semi-auto, the Stryfe Mission Kit is good too. And, if you want to go to the very basic level, the Strongarm (aka Elite Maverick) could be a choice as well. Sorry for the long answer. :-D

On the outside they're pretty much the same size; however, what you don't see is that the internal plastic stem on a Streamline (aka a Clip System dart) is longer than it is on an Elite (as well as Suction and Dart Tag darts). That means that the barrel post can't go as far into a Streamline dart's "hole" as it can on the other kinds of darts.

In other words, even though they're the same size on the outside as Elite darts, the old Streamline darts will NOT work on most Elite guns (I believe they may work on Elites like the Hailfire, Stryfe and Stockade, which use flywheels to fire the darts, but will not work on the Retaliator, Rampage, Rough Cut, Strongarm, and other guns that rely on air plungers).

Elite Darts, on the other hand, *will* work on guns designed for Streamline darts.
