Stealing Team Rocket's Shadow Pokemon and ensuring a NPC can identify them as rescued former Shadows

Shadow Pokemon in this game don't break the rules of the game in some absurd way, they are not "Shadow-Type" Pokemon who resist all attacks and hit all types Super Effectively. They keep their usual types and usually keep their moves, though there are some powerful enemy-only Shadow Moves for Shadow Pokemon to use. Only fundamentally evil people can use Shadow Pokemon, anyone else who captures them and rescues them purifies their hearts instantly. Wild Pokemon in my game have their offensive stats multiplied by 1.5x and their defensive stats multiplied by 3. Shadow Pokemon in my game have their offensive stats multiplied by 2 and their defensive stats multiplied by 4. Shadow Pokemon are an excellent mechanic for letting the player capture powerful battle-ready Pokemon during standard gameplay, and it's better than separating the acts of battling and catching into battling powerful enemy Trainers and catching nonthreatening Wild Pokemon. Defeat a Wild Pokemon or Shadow Pokemon for a guaranteed chance to catch that Pokemon. Or join Team Rocket and catch all the Pokemon of every Trainer not in Team Rocket. This game wants you to earn your victories and the Pokemon you catch in and out of battle.
