Well it's certainly strange answering my own question, but . . .
In Blue, the only way I have come across is using the BugFrag Trader in Secret Area 3. It's not a lock, so you'll have to keep at it time after time before you get one. Some sources will say that someone in the DNN studio will trade one. This may be true in White, but it is not true in Blue, unless my ROM is a hack.
The styles in MegaMan BattleNetwork 3 Blue are: Custom, Team, Guts, Shield, Bug, and the Blue version exclusive Shadow. They will be in tandem with the four elements fire, water, electric, and wood.
Serenade from Megaman Battlenetwork 3 is a boy, as he is referred to by both Lan and Megaman as a boy, and holds the title of UnderKing. I cannot account for other characters named Serenade in the Megaman franchise, though they are likely the same gender.
Rank 2 is obtained from Bowlman in Blue and Mistman in White. Both are located in the battle terminal in the DNN studio. Just jack in, talk to them, battle them, defeat them, get rank 2.
In beach st. When you take the subway (Lan, not megaman) The moment you come out, you should see some guy near the outside of the subway. So in beach St. He is wearing a blue shirt and has brownish hair, talk to him and buy what he is selling. Hope that helps.
Oh boy. Search Megaman Battlenetwork 3 White ROM on Google and you'll get enough hits on the first page to download at least 3. But don't ask that question. Please.
Fire + 30 is obtained from the bugfrag trader in Undernet 2 using the gargoyle on HadesIsle. Blackbomb 2 is behind Flashman's security cube.
In Megaman Battlenetwork 3, the WWW ID is available from one of the Sci-Lab jobs, available from the Job BBS. I think it's the job called "Help with Rehab." Go to the Hospital TV to complete it.
Rank 9 is in HospComp 2, using the warp point in Beach 1 past the Hosp Security Cube, which is bypassed with the HospCode Mamoru gives you. There's also a blue mysterydata there.
Hospital Comp 2. But not from the hospital basement: from Beach 1 using the hospital code which Mamoru gives you.
You take it back to the ghostnavi in the principal's computer. He will forget the clue to Rank 6, BUT, (of course) Chaud e-mail's you that Rank 3 posted on the ACDC BBS talking to you. You check out the message, and go meet him in Undernet 4.
no you can only link megaman games together if it is the same number like megaman battle network 3 blue to megaman battle network 3 white
