With the death of a member of the Fantastic Four, the series is about to end. We know there will be an FF series but it looks like there will not be a Fantastic Four. Why is this? Can't the team continue with someone else? Would replacing the fallen hero simply be too painful? 
 
Marvel has released the following image from the final issue of Fantastic Four. 

Update 

Will Spiderman succeed in pushing Franklin off the roof?! Will Sue ever find out how to properly spell She-Hulk? find out in the final issue of Fantastic Four! 
 
But really, this looks very interesting cant wait to read this.

Fantastic Four lost its appeal a long time ago.

looks like spidey is gona give some advice to franklin about losing an uncle

" Will Spiderman succeed in pushing Franklin off the roof?! Will Sue ever find out how to properly spell She-Hulk? find out in the final issue of Fantastic Four!  

Man, Mr Fantastic(?) doesn't look too good. He's probably been keeping himself busy after what happened.

I smell an emotional speech involving Spidey's favorite catchphrase.  "

Ok, Hickman says they are going to FF But not the Fantastic Four, so what are our name choices?    Future Foundation?  Fantastic Family?  Fantastic Force?
 
They have already promoted Future Foundation ...
  

 
And The Fantastic Force has had two incarnations, the first occurred when there was a death in the Fantastic Four (sound familiar?).

 
And ended with Reed's return to the living....
 

 And so ended the first Fantastic Force. The second Fantastic Force was a reboot of the New Defenders, who were introduced in Fantastic Four 558, and come from 500 years in the future who were originally lead by Reed and Sue Richards (who both stopped aging).   



 
It is interesting that Logan recommends the name Fantastic Force, but if you look at "old Sue", she is clearly wearing a Fantastic Four outfit.
It is probably fitting to become the Fantastic Force for a while until Johnny Storm's re-ignition. 
 
If Ben were to leave the FF (and become a full time Avenger), then Reed, Sue, Franklin and Valeria could become the "Fantastic Family" and still use the "4", but the is little chance in Hell Ben would leave the kids now that Johnny is dead.  If anything he will be overly protective, as he will be feeling guilt for their uncles death.
 
So even though it is obvious and has be done before, I think Fantastic Force it will be. At least for the next 11 issues or so.

i dont like it when marvel does this. watch, a couple years from now whatever FF series is going is suddenly going to start back up w/ these numbers to come out with a 600 issue or whatever. 
 
i can see how this book was underselling though so i guess it makes sense. although i heard it was amazing

Why does the Invisible Woman, if that is her, look like she is 12 ?

what a burn...

see spidey's creeping in already!!!

 Alex Power led the "Power Pack" team, which Franklin was a member when he was younger.  Super kids. Valeria was right to cross him off the list.

"@DEGRAAF: It's Probably She-Hulk, Storm, Black Panther and Wyatt Wingfoot. They were all members of the Fantastic Four at one point or another. "

They should call themselves the "Terrific Three" now...

This makes me more excited for the next issue then I was and I thought that was impossible. 

"Will Spiderman succeed in pushing Franklin off the roof?! Will Sue ever find out how to properly spell She-Hulk? find out in the final issue of Fantastic Four!"

It's only a matter of time before he comes back from the dead, they never stay dead for long in comics.

Spider-Man wants to join, so he talks with the F4. That really is obvious with Spider-man on the picture. I wonder if Spider-man remembers that the F4 are non-profitable (hopefully) and it looks like he's also in his original suit. Maybe he lost his job (again).

they should go get Iceman.  That could actually work.

The repercussions should be as powerful to read as the "death" issue was.
 
Reed not only has to deal with Johnny's loss but now must 'solve everything'.

It shouldn't last!!! Fantastic Four would’ve reach’d #600 soon. I think they’ll do the FF thing for 11 issues (about a year) then come back with #600. And as for the images, Spider-Man talking to Franklin makes complete sense with the effect Peter’s uncle passing had on his life (in and out of his costume). Valeria whipping away the list of potential members might show the fact that she has to deal this on an emotional level and not just an intellectual one. And finally, the list points out that this has really hit the family and they WILL NOT be taken by surprise again with any threat and might even represent a change in strategy to possibly become more preemptive concerning threats.

They should get Batman.

Spider-Man shows up to console Franklin Richards, according to a solicit I had read for #588.  As for Valeria, it said nothing about her.  The last picture in the teaser image is what has ME curious.  Is that Reed?  If not, who the hell is it?

Franklin will develop his powers and becomes the fourth member... :)

Doctor Doom should be the fourth XD, as Namor is with X-men.

Fantastic Four has been part of my reading for nearly 25 years. It has not always been good. So ending this title is a sore spot for me. Johnny dead... as far as i go it really isnt an issue. He was the only one whos loss is not going to shake the world. At one time or another they have been replaced for better or worse.  
Happy ? no .. interested....maybe. Angry?  yep

Johnny isn't dead. 
Hickman left it wide open to bring him back. 
When we last see Johnny, the Negative Zone hoards have descended upon him.  Then the portal closes before we can see what happens next. 
The easiest thing to do was say that Johnny waited until the last possible second and went super-nova on them.  And now, after crispifying the monsters, he's stranded in the Zone and potentially powerless. 
It would only make sense for Reed and crew to go back and see if they can recover whatever, they assume, is left of Johnny.  Upon re-opening the portal, they find him sitting in the middle of a pile of ashes with a huge smile on his face...saying, "What took you guys so long?" (or something like that). 
If that doesn't grab you as a possible way to bring Johnny back, just remember...Marvel is planning to reboot the movie franchise.  There's no way they'd do a Fantastic Four movie without the Human Torch.  They might get away with it in a cartoon (and they did...WAAAAYYYY back), but not in a live-action feature film.
