Sophih,
If you go to ebay.com, and search 'megaman manga' or 'rockman manga' you should be able to find something there. Check back from time to time if you don't see what you want.
I believe that they span from X1 to X7-the 6th I have yet to see for myself and I have only seen one or two of X7.
Mostly X1-3, sometimes X4. Most commonly the one that has Zero's face on it showing his hair without his helmet. He has half a forehead of bangs-but I guess there has got to be a tradeoff somewhere. Occasionally I see X5. Now there's a whole lotta MMnetwork, originals, and mixups.
Careful, while ebay is generally ok when you have the hang of purchasing, and eventually selling, there are con artists and creeps out there, as well as the less-than-ethical types who don't either give you anything, don't give you what you paid for as adverised, or service is lousy. for the most part it's ok. just watch those sleaze bags.
Oh yeah, there's plenty of action figures here and at other REPUTABLE places
like
Toywiz.com
toyattack.com
Toycup.com
and maybe
animedavesworld.com
Some like toywiz will offer incentives to join-like discount coupons.
There are probably more places for comics like right at the publishing source(s). I don't know who these are or if they sell directly. sorry.
I'd be careful elsewhere from ebay and these stores-especially if you have issues about perverted hentai. Some people-probably most people into anime 18+ like it. (most aren't very well drawn) Hentai comics of the legends series seems to pop up most. They're common in Japan. I guess those people must really be stressing with no life to be so obsessed. Dounjishi i think these are called. Still there's ID fraud, weirdos, and the like.
(If you're into it-take a a few drawing classes-don't potentially waste $ on something that may eventually be lost or stolen anyway and won't be worth squat (except frowns and laughter) for collectibility when we get old-the skills will last longer and you can make whatever you want to. )
For the rest of us, HOWEVER, I think we're all content with our imaginations and speaking to each other through forums and the music (THANX MUCHO!). More decent that way I think.
Anyway, of action figures there are amreican and japanese styles. Then there's just simply the EXE battle network types.
You'd be LUCKY if you found any original series megaman AFs. There's the later produced manga types which are more common, and lastly there's the OLD originals AFs and minifigures which are HARD TO FIND! These originals look like the original cartoons which came out around the same time. I have ONE 1994 protoman AF, and 4 minis--NOT FOR SALE!!!-- in my collection; Roll, Dr. light, cutman, and gutsman. I just wish they made an original gemini man with a buster arm with either a red laser or a blue LED. (not a bad idea with a plastic molder...)
Good luck and happy megaman shopping Sophih.
