You know I think Shards character could have need so much more character development. Like for all the trauma and insecurities he had/has to endure ... in a world, which hold (atleast a little) grudge against artifical life ... due to Eggman.
He was a famous killer robot. Mocking animals ... maybe killing them?? I know Sonic universe ... kid friendly and stuff, but these sharp fingers aren't there for nothing ... He might was causing a bad future, where every living thing is a robotic slave ... he saw how the Eggman Empire could have been. And now he tries everything to adjust to the "good side". Finding a place in the world. Seeking for forgiveness and a chance to prove himself.
Maybe he even can't move on from this. Alwayd playing the brave clown, while he's actually scared and frustrated. He probably stuck in his past. Always confronting himself, blaming himself ... Everytime he looks in the mirror he might not even see his current appearance ... just this menacing stare ...
Also, what I believe to recognize is that Eggman seems to got softer over the years. You know like in the beginning he hated nature, life itself and Sonic (of course) so much, that he just wanted to destroy everything. But nowadays it seems he has fun challenging the rodents. It's more of a game ... So I thought it would be interesting if his designs were gettin "softer" too.
And Shard might has the trauma of failing. Never won a battle alongside Eggman. Never enough for Eggman. Constant failure. Everytime reprogrammed. Everytime upgraded. Yeah of course does he want to constantly prove himself.
And yes then there is the fear of abandonment. One mistake and you're just scrap. Trash. You will be left to rot. Nobody will help you, repair you and give you a second chance ... and with Chuck exactly giving him this second chance, he might be really afraid that this hedgehog, this father figure, will also leave him, when he fails.
Oh and then maybe sometimes ... old habits sneak through. I also think there is this fear to go back to his old ways. No control about his "darker side".
I just love these redeeming characters. They try their best π
