7th...dammit.  The doppleganger one had me for a while.

Yeah I found everything on the one pages this quest is about with exception of the Copy Cat ones. I have no idea about anything related to this publisher, so could someone give me some "for dummies" level hints

" @ComicMan24: Try checking out some of the characters that ol' Robbie-boy created. Dude never met an original idea he didn't rip off. :D "

19th or as I'm gonna refer to it as: In the top 20.
 
Something I noticed about a character while I was searching away...
 

Doppleganger one has me completely stumped.  Any suggestions?

Just started on the quests :|

" #1!!!   Isn't it nice to have a quest where none of the answers are Supes, Bats, Jean Grey, or Iron Man.  "

" Doppleganger one has me completely stumped.  Any suggestions? "

"Gah, Liefeld probably can't take a crap without copying someone else. "

#49 to finish

Still need copy cat :\

Man that was hard enough! I spent ages trying to figure out the Copy Cat category...

"Still need copy cat :\ "

Got the quests thanks to help. :D
Also level 29 now.

Finally a quest in

Another hint for CopyCat is the member of Youngblood that is a Captain America ripoff 
 
I, too, was shocked that Fighting American didn't count towards this section of the quest, but then again Rob-o did that ripoff while under the "Awesome Comics" imprint, rather than the Extreme imprint

Took me longer than expected...I was searching for an answer I already had...should really check what i spam, i couldn't tell anyone an answer, im not sure what worked and what didn't lol

#83 to finish.
