The Supersons isn't a story of Damian's redemption or development on the contrary it ignores a lot of his redemption and development.
The Supersons is a story of Jon Kent becoming a hero despite being paired up with that awful Wayne kid.
Damian doesn't grow in the Supersons. Her doesn't do anything we haven't seen him do before and he isn't anymore heroic. He's actually less.
Even Maya who was with Damian on his year of Redemption is written as not seeing Damian as all that heroic. Maya! The one who said that Damian's R was about Redemption. Even her ignores everything they did together in RSOB.
Supersons was about Jon becoming a hero, the boys learning to get along [Dini already wrote that story and better for Damian] and having adventures together.
The only thing Supersons does for Damian's redemption is predict that he isn't redeemed. It shows that all that nonsense about Damian's redemption is just that nonsense because Jon doing bad in the future is due to Damian.
The book threw Damian under the bus majorly for the sake of Jon.
I find it odd that fans claim Damian is regressed in Rebirth aside from Supersons when the reverse is true.
Tomasi and Percy are two writers who regressed Damian's development.
Percy's Damian at least made new strides and was far more heroic than Supersons. Wanting to make friends, follow in Grayson's steps, learn to lead, was more mature and more than anything else he was ready to lay dowe his life for his new team shortly after meeting them. Percy's Damian was also trying to save The Fist because it was the right thing to do not because he was being petty and wanted to prove something to Batman like Supersons Damian was.
Tomasi regressed Damian to spotlight a new character and his Damian wasn't especially mature or heroic.
The truth is that Damian in Supersons is the only version that is regressed. Of all the writers who wrote Damian since 2016. I can point someway they have added something new. Some growth. supersons Damian is the only one who has gone backwards and not forward.
He doesn't do anything we haven't seen him do before.
If Tomasi wants to do a story about Damian's redemption/friendship then Maya is the better character to use since she is the one character that symbolises this.
Maya should have been the guest in this celebration of Damian as Robin not Jon.
Damian's Robin is indeed about suffering and continues to be all about that. Tomasi is making the same mistake Tynion and Synder did with BRE though on a smaller scale.
