Mr.Thunders
Striker
Don't think he had a definitive plan with it. He could set it up well, use clever techniques and callbacks to what's been said in the show previously to make it look a certain way but also leave it open ended. The fact that he's never came out since it finished nearly twenty year ago and said he died or didn't die kinda goes along with that as well.
Always thought part of the reason he left it open ended was in case the show came back in any way in the future then they weren't gonna do it without Tony.
Iirc the creator said something like "we all die" at the end.
