Ninjas. Sure, storm Shadow was cool and making Snake Eyes a ninja was interesting, but after that it was just lame.
C'mon, a Samurai? Really? In fully Samurai gear? Don't get me wrong, I loved Samurai's as a kid, but even I knew that was stretching the credibility.
Then we have Quick Kick. A guy running into battle shirtless, bear foot with some ninja stars, sword and numb chucks? I don't recall to many Kung Fu guys throwing around Ninja Stars. Fast times at Ridgemont High had it right. "No shirt, no shoes, no Dice".
Speaking of Dice, Slice and Dice was another lame idea. The only way fo the names to be "cool" is if both guys are standing beside each other, and even that's a stretch. Do they pee together as well? Storm shadow had his little red army of ninjas, that should have been enough.
Soon everyone was a ninja, including Scarlet. WHY?
To top it all off, they helped kill the line with those stupid action features.
Yes, I believe ninjas are the reason the toy line died. The original kids got older and went, wait, sword vs M16? I know who I'm backing in this fight.
