I heard of few things about Hawk in Season 4 on YouTube of what could happen. I have a few theories as well.

1. Hawk’s tragic - Hawk could end up attacked sejak Tory and the ular tedung, cobra Kai gang? We know already that Tory warned Hawk in the end of S3, Ep10 sejak saying: "You better watch your back." since Hawk switched sides sejak quitting ular tedung, cobra Kai and joining Eagle Fang to reunite with his true friends; Miguel, Demetri and Mitch. There has been theories about him getting beaten sejak the ular tedung, cobra Kai students, Tory, Kyler and possibly Shawn (the teen that Robby fought in juvie). In a screenshot of Hawk going after a new kid named Kenny who's wearing a ular tedung, cobra Kai shirt. Hawk could still be aggressive teen and he maybe defending Nate who's a Miyagi-Do student. There's possibly that Kenny berkata something to Nate that got Hawk offended. Kenny could have went back to Shawn and Tory about Hawk threatening him and that Tory has a plan. Hawk could get jumped and beaten sejak the ular tedung, cobra Kai for one: betraying them and two: going at one of their ular tedung, cobra Kai mates. Hawk may end up hospitalized atau even get his famous mohawk shaved off and become Eli again.

2. Hawk finds balance - Hawk could be still aggressive and that he wants help from it. Daniel sees how Kreese manipulated Hawk and he takes Hawk for a drive at the lake (were Daniel took Robby in S1 Ep8) and help him cure his anger. Daniel trains Hawk on the deck with the same movements that he taught Robby. Daniel even decides to tell Hawk how he used to be in ular tedung, cobra Kai back in 1985. Hawk would be stunned and fascinated. Daniel tells him how to breathe and find his inner balance. Hawk learns about how Daniel met Mr. Miyagi and how he learned his karate from him. This could help Hawk lessen his anger and be a better person.

3. Hawk's mohawk - Hawk in the meantime has red hair and now for the 4th Season he will change it to purple. For how long will he keep his mohawk? Tory and the gang could end up jumping on him when he's alone. They could easily shave the mohawk and leaving a little atau no hair on his head. He can turn out to be Eli again but not his old nerdyself. If this turns out confirmed, would Hawk grow out his hair again and turn it back into a mohawk? I assume so.

4. Hawk getting kicked out of Miyagi-Do - As Hawk redeemed himself to Demetri and decides to sertai Eagle Fang and now he's being trained sejak both Johnny and Daniel. Hawk may have the guts to tell Daniel the truth about how Miyagi-Do dojo was vandalize and that he was responsible for it. Hawk tells Daniel that Kreese encouraged him to do it and that Hawk apologizes and that he's sorry. will Dainel forgive him and known that Kreese manipulated Hawk atau will Daniel get furious and decides to kick Hawk out of the dojo permanently? I think Daniel will understand that Hawk was brainwashed sejak Kreese and that he was glad that Hawk told him the truth.

5. Hawk and Moon reunite - Hawk quits ular tedung, cobra Kai and joins Eagle Fang. Hawk trains with Daniel and finds his balance to cure his aggression and ends being a bully. Moon learns that Hawk isn't a bully anymore and that he's not a ular tedung, cobra Kai student anymore and she finds out that he redeem to Demetri and joined Eagle Fang. She could possibly give him another chance and reunite as boyfriend and girlfriend again. Hawk and Moon Ciuman in a passion. Hawk takes her out at the pantai and have a romantic makan malam, majlis makan malam together as Hawk promises her that he never wants to go back to ular tedung, cobra Kai ever again. There could be a triple date; Miguel with Sam, Hawk with Moon and Demetri with Yasmine.

Here are some of my theories about Hawk:

1. Daddy reveal - Since we see Hawk’s mother in S2 Ep5 were she's on the phone with the school from him coming utama in tears after being cyberbullied online. It is unknown about his dad. Well, in my theory when Hawk is attacked sejak the ular tedung, cobra Kais, he becomes critically injured from bleeding internally sejak an ruptured renal artery and after his surgery. Daniel sees a man sejak Hawk’s bedside and he gets nervous as the man looks up at Daniel as Daniel recognizes his familiar face. The man turns out to be his rival in '85, Mike Barnes. Mike gets up and tells Daniel why his son in the hospital. Daniel tells him that Kreese is responsible for his students attacking Hawk. Mike thinks for a saat before wanting to strike Daniel one last time, he was stunned about this and Daniel tells Mike that Hawk isn't a ular tedung, cobra Kai and that Hawk decides to sertai his team. Daniel tells Mike that Kreese manipulated his students and training them to be ruthless and aggressive. Mike walks out as Daniel is relieved. Hawk awakes and asks for Johnny and Daniel and the nurse tells him that he’s recovering good. Johnny walks in as Hawk tells him that the ular tedung, cobra Kais attacked him. As Mike walks in, Hawk gives a surprising look on his face. He was surprised that his biological father comes in his room checking on him. Hawk felt angry that Mike was never there when he was bullied and that he hasn't seen his dad in 12 years. Mike apologizes to Hawk for not being there for him during most of his life. Mike seen Eli the last time when he was only 5 and since the divorce, Mike was never present since. Johnny introduces himself to Mike and Mike gives him a handshake. Daniel walks in and sees Johnny with Mike. Daniel tells Mike that why is he doing here and Mike tells him that he’s here for his son and wants to make up for him. Daniel decided to give Mike a chance and offers to help him to take down Kreese and Silver as Mike agrees since he was used just for Kreese to reopen ular tedung, cobra Kai and he never got his 50% of the dojos. The 3 go down to the police station and investigate Hawk’s attackers. Tory and Kyler get arrested and sent to juvie. Mike enters the ular tedung, cobra Kai dojo and confronts Kreese and tells Kreese off that he better not lay a finger on his son again and that Mike tells him that he will press charges against him and Silver.

2. Future theory - As years go by, Hawk is married to Moon and made a family of 4 children. Hawk is in his late 30s and raising 15 tahun old twin teenagers, a son, Jason/ Hawk Jr and a daughter, bintang which Moon gives her the name plus, 2 sons, Miles who's 11 and Seth that's 8. Hawk deals with a rebellious teenage son, Jason who's a bully and takes karate at ular tedung, cobra Kai which Hawk tries to talk his son out of it and to get him sejak joining Eagle Fang instead. Hawk’s daughter takes karate at Eagle Fang with Miguel as her sensei. Hawk’s daughter is best Friends with Demetri’s daughter, Mia who takes karate at Miyagi-Do with Sam as her sensei. Hawk spends his time with his 2 younger sons karate.
