Anime where characters use other humanlike characters/monsters with powers to fight (JoJo/Shaman King like)

Im currently watching Shaman king flowers, have seen the original of course, and wanted something similar. Characters that have or borrow power from other human like/monster characters and fight.

I think the only other anime that ive seen with something similar is JoJo (stands) Not looking for ki like powers (dragon ball/bleach/naruto etc) or non personality powers (devil fruit/ generic super strength/speed etc). I want to actually see the character that gives the power to the main characters.

Any genre is welcome, any episode size is welcome, i just need decent animation and for the anime to be finished/ongoing and not on a hiatus/cancelled
