Hierophant Green - I have two move ideas for this stand.
Possession Grab - Grabs its enemy like Blood Suck and holds onto them with its tentacle.
Inside Possession - Goes into the enemy like Santana and can damage the inside of the enemy.
Kars - Like one idea for this spec.
Bird Form - You need ultimate life form (not in the game yet but probably coming soon). You can transform like Doppio 2 Arms and you pop out wings, you can fly using Z and its replaces J with a Feather throw. You can also spawn in hostile animals. Like a snake.
Thats all i have for now, they are not that great but i tried, ill probably add more.
