Sprite animations featuring Mario and Sonic aren't something new on the site. This includes even the way you displayed them here in a dragon ball or anime-esque presentation.
A little tip as well, NEVER EVER FLIPPIN EVER use the nintendo logo or sega logo(or any trademarks for that matter, that's the R thing in the circle) You are 10x more likely to get DMCA'd(though that is uncommon here to my knowledge) simply because a company can actually lose their trademark if they don't control who is allowed to use it, where they display it and what form it is displayed in. That being said they also aren't actually affiliated with you in making your sprite series so it's pointless credits.
However, none of this is why I gave you a low score.
There isn't too much to the animation. there are a ton of sprite sheet loops and even more still of the characters doing nothing(though I do understand that is very anime) but just makes the video lacking. As an intro it is very long(again I know, anime) which can suck if you see it before EVERY episode you will make and frankly the fact it's a swf means you also CAN'T skip it. Like at all. I'm sure someone out there could do some html voodoo shit but it would probably take most people longer than the intro itself lasts.
Also because you used the Dragon Ball Super opening I'm sure you are aware "The World's Strongest" is also a movie title in the series and I believe you also could probably come up with something better and more fitting that describes this series(I honestly have no idea what it's about yet. Looks like SMBZ to me).
Lastly another point that reduced your score for me was that it's an opening. That's great you put a lot of work into it and all, but if we'll be seeing this opening inside of future animations by you, I don't see a reason that it needs it's own place on the site.
I'm not going to blam your submission because I feel you are probably proud of your work(which is what Newgrounds is all about) so I'll simply give you a lower-middle score to represent what I've summed up here, hope you take some advice from mine and other people's reviews(because " FEEDBACK IS MUCH APPRECIATIVE!") and leave the blamming and saving to everyone else on the Under Judgment portal tab.
