Sorry this took so long to get out...but life sucks so that kinda slows things down.
Anyway...
Grammar
The grammar in this story is pretty good for the most part. There were only a few typos and misuses of commas. The only thing that I'm super nit picky on here is the titles. The words in the titles should all be capital, except two or one letter words. (Except I and And. And has three letters but it can be lower case. I is one letter but it can be capital.)
Example: My Undead Mummy and I

Plot
The plot of this story follows Sierra Storm has she deals with the loss of Jason Todd, who in the end isn't even dead.
All in all the plot was pretty okay. I'm not a big fan of the whole "plot twist, I'm not dead" thing, but I guess this story kind of made it work. I'd suggest more slow scenes though. In the flashbacks there were lovey dovey scenes, but they usually only happened when Jason and Dick were arguing or when the group was fighting a villain. This doesn't exactly make me feel for Sierra when Jason is allegedly killed.
If there were a couple of slower scenes, I think it would be easier to connect. For instance, Jason buys her flowers or the two go on a movie date where they open up to each other and spill some secret not even their best friends know. It would make their relationship feel more real and heart wrenching when it's over.
The last nitpicky thing I have for this part is the way that Jason comes back to the good side. (So to speak.) It seems rather random to me. I know Sierra is supposed to have talked him out of being evil ot something, but it just doesn't feel believable to me. Maybe add a scene where he is seen struggling with the thoughts after the conversation?

Oc
Sierra Storm technically isn't an oc, but the way that she was written in this story is completely original, so I think it counts.
Now, I'm not really the biggest fan of other people's ocs. I get annoyed by them very easily...Sierra does at least one of the things that annoy me.
Taking down an enemy like this is just lazy writing, in my opinion. Especially with the way this guy was described. Even with super powers it should take at least a good five minutes to take this guy out. Sierra does, in fact, have powers. Ice powers. But she doesn't use them here. Even if she did I'm not sure it would make much sense, unless she had super strength. (For one thing he must weigh a ton, and there's no way someone so much smaller than he is could lift him this way.)
I imagine this scene is probably meant to show off Sierra's bad assness, but it just makes her appear majorly op to me.
Another thing: Sierra always seems to know how to get out of trouble. She's arrogant because of her powers, which would make a good character flaw. But having her easily escape every bad situation makes the threat kind of boring and...basically not even a threat. Having a few times where she's completely clueless might help with that.
Other than that, I think she's okay. She's kind, heroic, feisty, angry, sad, all normal people things.

Cannon Characters
Admittedly, I'm not very familiar with the comic versions of the Bat Family. But from what I've seen, they're pretty in character.
Bruce is brooding (as usual ) and insisting he do everything on his own.
Dick is a flirt but has a good heart
Etc etc

Writing Style
So, the writing style was pretty neat. Lots of detail. Detail is good. Only two things that I'd suggest here, honestly.
One) Sometimes, you get carried away with the dialogue and just assume the reader can figure it out. This is a lot of work, and it makes reading the story difficult and uninteresting. Whenever there are more than two people speaking, make sure to tell the readers who is speaking, otherwise we will get lost.
Two) Italics for Flashbacks. This is by no means wrong. I've done this one myself in the past, but I would suggest trying other methods as well. I've heard from several people that reading too much italics is a pain. So, it's best to just keep that to a minimum. I'd suggest putting the date at the top, so the readers know exactly what time period the events are taking place in and you don't have to use too many italics.
