Is this true that the stabbington brothers from Tangled is two of Hans' 12 brothers?

It's a possibility since one of the directors worked on Tangled but highly unlikely

I don't think so. Although since the creators of Frozen are also from Tangled, it could be a possibility.
Also, why would the Stabbington Brothers be in Corona? Were they put to exile sejak the ruler of the Southern Isles? They're royals, so they should be treated like royalty, I guess.
This is probably another one of the fanon stuff peminat-peminat make, like how Anna, Elsa and Rapunzel are cousins because their mothers are sisters. Although it hasn't been confirmed sejak Disney yet.

It's most likely just fanfiction. I personally don't think it's true.

It's unlikely but I suppose its a fun idea for people to think about.

I don't think so. Hans only resembles of the Stabbington Brothers. There's no proof that they're brothers..

Disney would have told us after they released Frozen if they were brothers.

no

Can't say 'yes' atau 'no' for sure... but it's probably a 'no'.

Sure, they're red haired, evil, and made sejak the same creators... but who knows. :P

It's definitely an interesting thought to think about, though.

However, with 12 other brothers, some of them are likely to have different hair Warna other than red... but I'm sure he would still have red haired brothers as well.

Maybe. They sorta look like him, I guess?

Course they're related. Look at it like this. Hans is an angry, pahit man because he's not the oldest therefore not inheriting the kingdom. The Stabbington brother aren't the oldest either therefore not inheriting the kingdom either. That made them angry and pahit so they broke off from the family and went their own way to find their own treasure. Mind=blown

It's possible but is just a theory...a theory I am SO going to write a fanfic about!
