#but Jason (post resurrection) is less fundamental to Bat stories than Tim is in general

[zahri-melitor]

In the alternative, where you posit Tim never existed or say Tim appeared in ALPOD and was rejected by the public, you have to square with the fact that:

Robin 1993 is one of the longest continuous solo ongoings in DC that DOESN’T belong to the lead character of a family, at 185 issues (it might be THE longest, actually: Jimmy Olson clocks in at 163 issues before a major title change, Nightwing vol 2 has 155, Lois Lane is shorter again at 137, and I can’t think of anyone else who touches them).

The only reason Robin 1993 occurred was because Robin I (and then II and III) sold so well.

There’s an argument to be made that if Robin I and Robin 1993 hadn’t been successful, we might not have got a Nightwing solo ongoing when he was returned to the custody of the Bat office.

Now imagine what the Batfam looks like without Robin or Nightwing as ongoing books. You almost certainly never got anything more than minis or extended minis for other characters not named Bruce Wayne. That’s what happens if you delete Tim from existence.

(And that’s before you discuss how Tim’s ‘team up Robin’ habits created the thing we call the Batfamily today more than any other character can claim)
