I have wanted to start up a blog on this site for a bit,and since dc is starting over i figured it would be a good chance to start. Note if there is any inaccuracies i apologize,i'm working with what i know of each character. With any reboot changes come to a character,some positive some negative. Following the currently ongoing flashpoint mini,the dc universe is confirmed to lead to a reboot,which isn't that new to dc,but this one seems to be the biggest since the original crisis about 25 years ago. They difference between this reboot and the others since the original is the sheer amount of a characters it is looking to affect at this point in time.   
 
There are supposed to be about 50 new number one issues to arrive at the end of flashpoint. This means a lot of reboots. So I am going to list some of the benefits and problems that could arise from the reboot from different characters. (Note with the unclear nature of what stays and goes some things may be wrong)
 
Superman 

• He doesn't have to deal with the political uproar of his changing his citizenship. As a Canadian i liked the story,why just help one country with all his power. But it matters not,because if he is rebooted he will probably go back to being the all american hero he is known for. For those who liked the story it could be a negative,but the character will have less political stigma.
• This may end up being a good way to adapt to the lawsuit for his character rights. Depending on the result of the lawsuit,the character could end up in a varied amount of situations. With the reboot they could change superman into something a lot more malleable if something were to happen. Once things are resolved they can begin adding a lot more of his status quo.
• A reintroduction of his rogues gallery. Many people are not fans of some of his rogues,long time readers can point to a good story for those rogues,but they are not well known. The reboot could serve to reintroduce the characters,building up the threat level to those that may have not been previously seen as a threat to superman,and getting new readers acquainted with some of the others. 

• The possibility of no Lois. See the reaction to one more day for more on this matter. Ruining the relationship of two long standing characters is rarely warmly received,and doing it by reboot/retcon seems to anger people more. Heck the last season of smallville focused a lot on setting this up,there was a whole show called Lois and Clark.
• No superboy? Conner Kent is a well loved character,with superman's seemingly more youthful appearance,and the nature of a reboot,the character may be fazed out,and that would be wrong.

• If your a fan of Bruce as the only batman,your in luck,that's a huge possibility. 

  

•  Honestly the bat family has more to lose than gain in this situation
• Batman Inc. may die before it begins,which is a shame for something with such buildup.
• Dick may have never been batman,or nightwing for that matter if they make him robin again.Years of character development down the drain.I really hope he is at least Nightwing at the time of the reboot.
• Same for Tim,he just came into his own,only to possibly return to being robin or not being in the picture at all.
• Oracle could go back to being batgirl ( which would ruin all the stuff with cassandra cain) and lose much of the character she gained after being paralyzed.
• Again it could all go unchanged but i'm speculating at possible results of a reboot,and these are possibilities that are uniquely caused by the reboot.

• Barry Allen fans are in luck,a lot of focus will probably be heaped on the character.
• The reboot itself would not affect him much. 

• This mostly pertains to Wally West,but since focus has switched to Barry at around the same time of this reboot,he could be outsourced,possibly never becoming the flash.
• Wally has years of backstory,including his family at stake,and has been active longer than barry,so he has gained many fans over the years that may be upset.

• The events of recent green lantern stories have been confirmed to still have happened,so little will change with the Lanterns.

• Possible renewal of interest in the character
• The possibility that he may move beyond the superfriends version in the mainstream.
• A possible greater exploration of the world of atlantis.

• His time in charge of Atlantis and various other plot elements released over the years could be put in jeopardy.

• Some lesser known characters may get the chance to shine,while others may be buried by it.
• The switch of writers among the issues could seriously affect the quality of each character.
