Okay. The way I see it, all 3 of those Shredder's are in the same place at once because of a Time Window malfunction while they were trying to send Serling back to the future.

Thanks pal.

This is really quite good! Thank you all who contributed!

Wow. This is very interesting. Kudos to those who compiled it and have shared it with us. It's awesome.

Thank you, it was very fun to work on. I'm about to start another watch-through of the series sometime next week, hopefully I can pick up on a few new things.

A few small additions.

I put in the events of "Time Travails" as 1406, and gave the founding year of the EPF a hard 1870 as clearly stated by Bishop in "Bishop's Gambit".

Also gave Hamato Yoshi the birthyear of 1953, based upon the notes of Lloyd Goldfine and Peter Laird stating he is 16 in 1969.

Cool. Thanks for sharing that, Nines.

Small change, but after watching season 4, I feel like that season goes on long enough to pin point the TMNT's 18th birthday as taking place in early season 5.

There are a few glitches in the time-line. Inconsistencies and of course paradoxes.

In the flash-back (fathers and sons) it is shown that Splinter is aware that the shredder is indeed an utrom. But in season 2 when they are in the memory pods he seems to act completely ignorant of the fact.

Then there is the small matter of the time spent by the turtles in all their time-travelling adventures.

Like in return of savanti, they spent three months in the past, but when they returned they returned to the exact same point they left. So did they age three months or not. It is a paradoxical question.

There are a few more. But these two come to mind.

Another reason why I hate season 5. Splinter seemed way too clued in on everything, when he should have been almost as lost as the turtles were.

My "no-prize" explanation is that after Splinter found out that Shredder was an Utrom, he contacted the Ancient One through the astral plane and got the whole story from him then.

I don't know why he wouldn't have shared all that information with his sons, but it's the only logical explanation.

Lol yeah, so the Turtles are actually a few months older than they are by Splinter's count.

This isn't something I thought I would have cared about, but interesting, nonetheless. And I can respect the amount of work put into it. Good job, dawg.

Thanks man, glad you liked it.

Does anybody know what year O'neilTech was founded? I just watched through Fast Forward not too long ago, but I didn't pick up on that.

Another interesting fact is TMNT 2K3 seems to subscribe to a single linear time stream. Which creates it owns paradoxes. Don was very particular about not polluting the time stream. But the very fact that they made it to the future and gain some info, however miniscule it was did indeed pollute the time stream.

Also since it seems that they follow a single time stream as opposed to the many worlds theory, it would not matter what the turtles did or did not find out while they were in the future, as once they travelled back, all the events that will happen from then on will have incorporated all the things they do know. Single time streams have to be self consistent.

Then there was the episode timing is everything, where Mike and Raph from the very near future, tell their very recent past selves to go home and look for an envelope and ask their selves to do the same when they get to the future. This seems to create a causality problem. Which version originated the thought/knowledge the first. It appears to be cyclical reasoning. They only know about the envelope don mailed from the past from themselves. Which seems to create a contradiction.

Then there was Serling travelling back to the past to meet the turtles as kids. Although there do not seem to be any contradictions here. Another example of a linear time stream.

One quick question while we are talking about timeline.

In the first episode of BTTS, the turtles encounter three shredders going at each other. Did that event actually come to pass or was it one of those cases where TMNT did subscribe to many worlds and alternative histories theory?

One other being when Don is transported to a bleak alternative future. Where, "there is no hope, there is only the shredder".

But Splinter visited the Ancient one soon after Yoshi was killed, when the turtles were still children. It was then Splinter uses the phrase Utrom Shredder. This according to chronology happened before season 2. Though this incident was revealed in season 5.

Then splinter acted as if he was unawares about Utrom Shredder's true identity in season 2.

I guess the only logical explanation is that it was just a continuity error in the script. Whether it was there deliberately or not cannot be answered without input from the writers. Or maybe the writers just chose to say to hell with it and went ahead and wrote the script for season 5.

It's just a constant loop. I love time-travel! lol

Personally, I think it was an alternate future. But if it did actually happen, I bet it all started when they tried to send Serling back to the future. Something went wrong with the time-window and somehow those 3 Shredder's were all brought to the same time.

Definitely an alternate future based upon Donatello disappearing in "late season 3" and not being there for the events of Exodus. I'm sure that mission would have gone to hell without old Don.

That's often the nature of the flashback episode though. I just chalk it up to the fact that that's how Splinter was differentiating the two Shredder's for the purpose of the story being told to the turtles.

Yeah, that whole season was just a wreck. Which is a shame, because the writers did such an epic job leading up to it with the late season 4 sub-plots.

Yeah Splinter mentioning the Utrom Shredder in the flashback was a plothole. Sadly the writers probably didn't realize they were writing something from the past when Splinter didn't know that Shredder's identity.

It can be shrugged off I suppose, just a continuity glitch.

Turtles Forever
 

Is Turtles Forever really a part of the official storyline? Isn't it just a "what if the TMNt from both shows met"?

I'm pretty sure Turtles Forever was supposed to happen. I was originally was going to be a two-parter of BTTS.

Of course not. When it aired on TV as 3-episodes, its official number destination was 158, 159, and 160.

And why the hell are people debating whether Turtles Forever was canon anyway? This is silly.

Uh... Yeah. "What if the TMNT from both shows met not long after the events of Back to the Sewer."
