Probably the darkest Pokemon movie for me (that’s not the first with Mewtwo killing all those people in the lab or the Volcanion movie, I just liked this movie more.)
What gets me tho is that Kodai pretty much kills Zoroark, between her exhaustion and ordering his Pokemon to attack her/electrocuting her himself. She legit died from all that, with Celebi intervening to revive her.
Plus, he strangles Celebi, holds Zorua hostage and tells its mother that he’ll kill it if she comes any closer (electrocuting Zorua to prove his point), and threatens to kill Ash (“No one will know what I did here today. I was only trying to stop the evil Pokemon, Zoroark.”) What sets him apart from Alva for me is that it feels more personal between him, Zorua/Zoroark, and Celebi, despite his actions being on a smaller scale.
