more than likely, you are one of the people that actually like Andrew Dickman/DN sama/ AWD's work. I did too, until the Rockman NEO fiasco. he "changed" RMNEO into a "completely original work". If you saw what the redesign of some the characters, you'd be screaming "That's bull!" like I am.
and that's not where it ends with NEO either. the fans of RMN (myself included) were working on the game he wrote the script for. but he never once thought to correctly elaborate on the characters' bios, and left everyone guessing. this is the point where things got hectic.
As an April Fools joke, one of team members recolored the NEO spritesheet pink and called it "Neo-ette" and sayed it would be a second character. Dickman took it seriously, and that's when he began getting ticked.
He called the RMN game project off, saying "I am tired of people making assumptions about my characters, and adding ideas." what were we supposed to do? he gave us barely anything to work with in the first place, so all we could do was make assumptions. He wasn't even doing one damn thing for the project. it was a "by the fans for the fans" type of game project.
fortunately, one of the leaders of the original RMN project, Moonlight MK2, wasn't going to give up so easily on the project. thusly, the project has come back, but this time nothing of Dickman's will be used. completely original material, and a new main character and name: Rockman Nova.

Another thing about him: he's a ripoff artist. "One Knight's Tail", a comic he's making, closely resembles Rocket Knight Adventures. And another flash and storyline, "Tail Chasers" is F-Zero with Motorcycles. and yet another flash, "Rotojin", is a ripoff of Medabots and Megaman Battle Network.
That's pretty much the major reasons I hate the bastard.
