Why do so many people think Jason Todd is Red X II? (Teen Titans, 2003)
I know this has probably been mentioned on the internet a million times but I recently watched the series and I just have to say that I don't understand how this theory seemingly became so widely accepted as "Canon" when it doesn't make sense like at all.
Quick note: I'm not saying people can't like the theory, not at all. Also I know the TV show's area in the general mainstream canon is already hazy as is. I'm just yapping because I don't have anyone to talk about this with.
General sequence of events relating to Dick and Jason as 'Robin':
Dick Grayson becomes 'Robin' around 9-12 after his parents die and he's adopted/taken by Bruce.
He serves as Bruce's sidekick in Gotham until about 15-16 when he leaves and creates his own team.
Dick abandons the 'Robin' Moniker at 18-19 to become 'Nightwing'. He was 'Robin' for 6-10 years
Around the same time Dick becomes 'Nightwing' Jason is adopted/taken in by Bruce, becoming the second 'Robin' around 12-13
Jason stays 'Robin' until his death at 14-15, having been 'Robin' for only 1-3 years. He was dead for 6 months and then stayed with the League of Assassins for 3.5-6.5 years
Around 19-21 Jason returns to Gotham as 'Red Hood'.
Given that in the show the main Teen Titans team seem already well established in their identity as the Teen Titans but Dick is still using the name 'Robin', I'd say Dick is likely 17-18. If the show is following the general sequence of events above Jason likely hasn't even met Bruce yet, let alone been given any of the training needed to do any of the stuff Red X II does. Not to mention Red X II is seemingly built exactly like Dick or at least close enough to be mistaken for him which is a problem for the theory since generally Jason is six years younger than Dick.
The theory just doesn't make sense when looking at any of characters general lives at the time. No version of the events make it possible for Jason to be Red X II. The only three things they have in common is their direct tie to Dick, a red and black color palette(which Jason would only get years later), and the word red in their monikers.
This was longer than I intended but if you read all this, thank you!
