Tadelsa

Tadelsa is the het ship between Tadashi Hamada and Elsa from the Big Hero 6 and Frozen fandoms.

Canon
As Tadashi and Elsa are from different series, they have never met in canon. Even though a few Disney crossover video games could have the two cross paths with one another or get them added in the same team, by the player's choice. Both Elsa and Tadashi are older sibling who care a lot for their siblings, Anna and Hiro. The two also lost their parents.

Fanon
Tadelsa is considered to be a popular ship in the Frozen/Big Hero 6 crossover fandom. The ship is also part of the  and its sup-fandoms. Since Tadashi is a scientist he would probably be fascinated by Elsa's abilities and may want to learn more about them, leading to Elsa having a better understanding and control over them. Fans also see Elsa being drawn to Tadashi's caring nature as he helps her to see that her powers don't make her a monster and how she can be more open around people. Other people see the two bonding over them being orphans who had took it upon themselves to watch out for their younger siblings. Since some fans include Anna and Hiro, as well as Olaf and Baymax, in group Tadelsa fanwork. The crossover ship has also been rivalled with Tadanna or have it shipped beside Hiranna.

There are times where the ship is set in Arendelle, but are mostly set in San Fransokyo, where Elsa is commonly seen as a SFIT student that Tadashi takes a shine to. Since the ship is commonly placed in a Modern AU setting. A few manips also have Elsa in Go Go's clothing or a BH6 armour suit. Along with some fanwork featuring both of them wearing Japanese style clothing. The AU's typically have Tadashi part of BH6, while Elsa is typically a civilian girl. The AU of Tadashi gaining power over fire has also featured in the ship, since Elsa has ice magic and it isn't uncommon to ship couples of fire and ice together. In a few versions of a Frozen AU, with the BH6 characters, Tadashi is sometimes seen as Elsa, while in Big Hero 6 AU with Frozen characters Elsa is sometimes seen as Tadashi Hamada. Since there were a few Frozen Easter Eggs and references in Big Hero 6, it got a few fans like to start believing that their films could somehow be linked. Just as many believe that Frozen could also be part of the Tangled universe, that is also believed to be connected to the world of BH6.

On AO3, the ship only has 14 fanfics while fanfiction.net has 42 with only 17 placed under pairing. Its fanbase on Deviantart and Tumblr, however, it a bit more larger than it is on the two fanfic websites. With the art relating websites having a group and a few blogs on Tadelsa.

Even though many Tadashi ships circle around the Tadashi Alive AU, there have been Tadelsa stories that do have Tadashi die. While having Elsa as his grieving girlfriend, or simply his best friend who had secret feelings for him. Some versions of this idea have Tadashi's ghost visit Elsa, so he could help her find peace from his passing. A similar idea has also been used in a few other crossover ships involving Elsa. As she carries the guilt and pain of losing the people she loves, who have either been harmed by her powers or had failed to save them.
