About this AUEdit
The Omnics, artificial intelligence robots and the other kinds of robots that exist in the world of Overwatch, can have this AU an alternative to Robot AU. While the countless wars and crime ways that stared and ended Overwatch, could also have it as an alternative to War AU.
The Big FourEdit
Fans have cast Hiccup as Hanzo, for his bond and connection with dragons and with fans making Toothless the dragon tattoo on his arm. Hiccup is also seen as Junkret, because of his prosthetic leg and having a weapon of fire. Fans also see him as Genji, as the two have made sacrifices, have a connection with dragons and with fans seeing his flightsuit and helmet-like mask as Genji's cyborg-armored body.
Jack's ice powers and being part of a group that protects people, he can be cast as a male Mei or a recent recruit to the re-recruited group. He can also be portrayed Jack Morrison (A.K.A. Soldier: 76), due to their color scheme and the fact they are both presumed dead.
Because of Merida's archery skills, being an older sibling, harming a member of her family and is familiar with a story that teaches people, she is seen as a female Hanzo. The dragon tattoo on her arm can be of Toothless - for the Mericcup pairing and the How to Be Brave crossover - or as the dragon that she is partnered up with in the Viking AU. Some fans, however, switch Hanzo's dragon theme with a bear theme, so the role can better suit Merida and the themes from Brave.
Because of their goal and task that they set themselves to keep the people of San Fransokyo - so they can honor their friend's wish of helping people - and the armor suits that they wear, they are seen as members of Overwatch. Portrayed as original members or as six resent additions to the re-recruited group, that posses their own skills, armor and weapons.
When they are portrayed as characters from the game, Hiro is seen as a male D.Va, with Baymax as his MEKA drone suit. Along with Honey Lemon being portrayed as Mercy, GoGo as Tracer, Wasabi as Lúcio and Fred being cast as Junkrat.
Baymax is commonly seen as D.Va's MEKA, when Hiro is a young, male version of its pilot. Baymax can also be placed as one of the robot members of Overwatch, like Zenyatta or a male Orisa (which could have Hiro as a male Efi Oladele); while his healing program has fans viewing him as male and robotic version of Mercy.
The style of Baymax's 2.0 armor could even have fans viewing a human version of Baymax as a member of the Crusaders. As their battlefield armor and helmets are a bit like Baymax's.
Because of Elsa's ice powers and having a small, unhuman friend, fans see her as Mei; with Olaf or one of the Snowgies as Mei's assistant drone, Snowball. Elsa has also been cast as Mercy and Widowmaker.
Anna is commonly cast as the young, spunky and fastest member of Overwatch, Tracer. Along with the role of Ana.
Pitch's powers and dark appearance can easily portray him as Reaper. As both characters have been separated from their families.
Due to Dagur's history with his family - mainly with his sister -, knows how to shot an arrow and has a connection with dragons, he is seen as Hanzo, while Heather is a female Genji.
Due to Heather's history with her birth family, has a connection with dragons, having armor as part of her clothing and was able to forgive her brother, she is seen as a female Genji, while Dagur is Hanzo.
Since Beetle's human self looks very similar to one of the Overwatch characters (with hair style), that is an archer and has the same name as him, it easily portrays him as Hanzo. Overwatch Hanzo's dragon theme can be switched with a beetle theme, so the role can better suit Kubo and the Two Strings Hanzo and his Beetle self.
Vanellope can be portrayed as Tracer. As the Sugar Rush Princess's glitching ability is a bit like Lena Oxton's (Tracer's true name) blink ability.
Because of his dark clothing and wearing a mask, it can easily have fans view and portray Yokai as Reaper.
