NONE of the characters from those silly tween sitcom on Disney channel would EVER provide anything useful to ANY Sentai team. And yes that includes Raven's lousy self-centered psychic powers and Phil's stupid futuristic gizmos that no one in their right mind would try to invent...or at least sell as a commercial product.
So you're telling me, when Tsubasa failed to get rid of Nai and Mea as Vancuria using a specially created weapon, a couple of annoying teenage girls are going to succeed with a cross and some garlic?
Seriously, now you're just sounding desperate.
Okay, I suppose I should dissect your Aba story now, since I'm bored and awake.
Length-wise, each chapter is by far too short. Not much else to say than that.
Your grammar and usage is really off. First thing, you suddenly switch back and forth between the past and present tenses. That is quite a big problem. You need to pick one tense and stick with it. Past usually works best. Second, when someone says something, you should start a new line. You don't just blend it in with the rest of the paragraph, like you do repeatedly. Third, you don't describe much. Yes, many people who are going to read this have already seen Abaranger, but you still need to describe stuff. Descriptions add quite a bit of substance to a story.
Not to mention the fact that I really don't get what's so special about "That's So Raven" that warrants a team-up with the Abarangers.
The normal anti-vampire stuff doesn't work on them! Don't you get it? It's a RULE of that particular universe.
I have an account on Fanfiction.net (same handle in fact) and, while I haven't posted anything in a LONG time, I regularly visit. I'm a huge consumer of crossovers for that matter.
You just don't try to turn a sitcom into an action show unless you end up giving those brats powers of their own.
Even there what self-respecting mentor character would do that?
Arnold, why is it so hard for you to grasp that normal stuff wouldn't work on Nai and Mea? They're not normal vampires.
More reasonable answer:
Said Sentai would find out the location somehow, bust in and lay the smackdown while said parents thank their lucky stars and think about getting back to their families alive and unhurt. Sorry to be blunt, but your idea is just unfeasible. Fanboy/fangirl ideas are all well and good but this is just too whack.
If I was the Sentai, I'd realize that training the kiddies would amount to time-wasting AND babysitting. By not concentrating on the crisis at hand, I'm just exposing the parents to more danger. Let's say I'm one of the rugrats, then.
"My parents are in danger, will you train me and not rescue them straight away? It doesn't matter if it takes at least two years to become a hero like you, as long as I can help you rescue my parents a couple years from now!"
Finally, if I was the parent I sure as hell don't want to see my kids exposing themselves to danger. If they did that, you can be sure the first thing I'd do after tearfully hugging them would be to ground them into retirement.
Guh. My brain hurts.
