Feeling terribly indulgent so I’m adding a few thoughts about whatever this AU is:

• Damian’s Decidueye is originally Dick’s first pkm (gift from his passed mother), but has been handed over, boy by boy, to teach them the ropes. He is patient, mature and protective of the boys he is tasked to watch over, but as a pkm more experienced than his trainer(s), he will occasionally disobey or act on his own. Decidueye’s name is Robin and by far Damian’s most powerful pkm atm.
• Miltank is a rescued farm pkm.
• Scizor (as Scyther) was caught during a bug contest Damian entered with Bruce as father and son. Damian is reminded of that rare memory, and that Bruce loves him despite being an aloof/distant father, every times he looks at Scizor.
