Yggdrasil from Norse Mythology is a large tree that holds the nine realms (Left Foot {Helheim} Right Thigh {Vanaheim} Right Foot {Niflheim} Left Thigh {Jotunheim} Center {Midgard} Left Arm {Muspellheim} Right Arm {Alfheim} Head {Asgard} Back {Nidavellir}
Around the Legs is Níðhöggr and on the back of the head is an eagle whose name has been lost and perched atop him is Veðrfölnir {a hawk}) I didn't have to do much research since I love Norse Mythology anyway. this is not based on the Marvel movies other than loosely Nidavellir because otherwise, it was not unique enough
