Think of it kind of like a pokemon nuzlock game. However, unlike the game the as the MC levels up he gets more slots for new pokemon on his team. Hans was the starter and Heinz is in the second slot. Since it's a nuzlocke when the pokemon dies it's gone. So Heinz I (zubat with a tough nature) died and Heinz II (zubat with hasty nature) took his slot on the team and evolved into a vampire (golbat) and eventually became a sacred blood (crobat).
But heinz II was his own slot? And the window said that heinz I could be resummoned after a week or sum?
Why is this a crazy good explanation
I think what happened was he had the option to wait 7 days to respawn Heinz I, but because of the kids he didn't want to wait so he just summoned Heinz II instead.
Ohhh this make sense, thank youuu
Re-reading this after a while, so where does Heinz I go? Did he canceled the creation after Heinz died and just use Heinz II? So he could use the extra slot? I keep thinking about it lmao
