I hope I'm not too late to this.... but I have a scenario....
A noob trainer stumbles across a rare/legendary pokemon, and tries to catch it. The Pokemon who is being targeted is disgusted by the noob, and repels all efforts on the trainer's part to catch it. The rare/legendary Pokemon makes clear that it has a date with another Pokemon, that it was headed to before the noob trainer spotted it.
As it walks away, The noob throws a master ball, catching the poor Pokemon. When it is immediately is summoned, it points out that the noob should not have had the master ball this early in the game, but the trainer just smiles and shows it their action replay cheat device.
The next time the rare/legendary Pokemon is summoned, it is in battle, with an embarrassing nickname. At this point it is fed up, and turns on its trainer. It beats up the noob, and captures them in a pokeball. Then it walks off, muttering about being late for its date. The End.
Does this sound neat?
