If Batfamily members were part of the Avatar (The Last Airbender) universe. Which element would each be able to bend?
It’s probably been done before by other creators, but I will write each one of my headcanons and why I think they’d bend that element. You’re free to think otherwise about these.
Water: as Uncle Iroh explained to Zuko, water is the element of change. The people of the water tribes are capable to adapting to many things. They have a sense of community and love that holds them together through anything.
•Dick - had to evolve many times in order to fit, whether from an orphan to a billionaire, a sidekick to forming his own team (the titans), or even moving cities altogether and becoming his own hero.
•Bruce - the original evolving character. He had to adapt from having loving parents to being an orphan. From being a one man show to having sidekicks and a whole team formed of superheroes. Whether he realizes it or not. He’s build a community around him to help the people that are part of it, feel loved and understood.
Earth: Earth is the element of substance. The people from the earth kingdom are diverse and strong. They are persisting and enduring.
•Cass - to begin and try to explain how enduring Cass is would be a whole essay on its own. She was raised from the minute she was born to be a living weapon. Endured years of abuse towards that goal. And much like Toph, she concentrates, analyses and concludes before she attack.
•Jason - I know Jason could arguably be added as part of the fire element as well. But he’s been one of the Batfamily members that has had to endure a lot. His parents abused and neglected him, he never adapted to Bruce’s moral code, he was killed by the joker and brought back only to be another soldier for the League. He is strong in more ways than just physical strength and has never stopped persisting about what his beliefs are, even if that has created a breach with his family at times.
Fire: Fire is the element of power. The people of the fire nation have desire and will and the energy and drive to achieve what they want.
•Damian - a lot like Zuko, Damian’s drive and will was at first conducted by anger, superiority and desire for power. But the more he has immersed himself in achieving his own goals, and not the ones that were imposed to him by other people, he has been one of the most strong willed and powerful members of the Batfamily.
•Kate - Since childhood, Kate has been someone that felt she lacked power over her own life. The kidnapping, the loss of her mother and sister, her expulsion from the military, and overall control of her destiny. But this hasn’t stopped her from achieving what she wants. The will she has is enormous.
Air: Air is the element of freedom. The Air nomads detached themselves from worldly concerns and found peace and freedom. Also, the apparently had pretty good senses of humour.
•Steph - having to detach yourself from your own blood is something incredibly difficult. But Stephanie proved this can be done in order to achieve freedom when she took the mantle of spoiler and helped Robin and Batman take down her own father. She forged her own path.
•Alfred - One of the greatest characteristics from air nomads is their ability to remain peaceful. With every single thing the bat kids have put him through, he remains one of the more sarcastic and empathetic members of the family, and also a true guide for each of them.
Non-benders: Having no bending abilities has never been an impediment for the people of the four nations. We’ve seen them being great combatants, logical thinkers and overall, people that had earned their place amongst the people that seem to be ‘most powerful’.
The following three are listed as non-benders is mainly the result of their efforts to prove themselves in order to be a part of the Batfamily.
•Tim - His own strength has always proven to be his intellect. No combat, threats or anything physical at all was needed in order for him to use his mind to act as the greatest detective of this family and find out Batman’s identity. His brain has proven more useful than any violent action. He earned his spot inside the family.
•Barbara - Much like Tim, Barbara proved her own way into the family. She started out as a potential casualty in Batman’s book, but she quickly proved herself to the family. Even after being incapacitated to deal with criminals hand to hand, her logical thinking has helped the family perhaps even more with her role as Oracle.
•Duke - after losing his parent’s sanity at the hands of the joker, Duke also proved himself with the ‘we are Robin’ movement. He couldn’t care less about how powerful anyone else was, because he knew that what the movement represented was far more important than walking amongst heroes.
*All of the above could arguably be moved from one element to the other, but this is my personal headcanon.
