Currently, the variety of spawns in the end is underwhelming. I propose considering adding spawns to the End that fit the following descriptions....

1. Psychic Pokemon (Drowzee, Duosion, Oranguru, etc)
2. Dark Pokemon (Alolan Rattata, Maschiff, etc)
3. Pokemon in Themes (Cats, Dogs, Vermin, Horses, Monkeys)

I will need to consider what to spawn further, because there is an overwhelming temptation to, say, find a place for every cat Pokemon when 90% of them are already placed; at the same time, however, I want to keep to a certain theme, as the player is not yet in the end-game.
