Which bosses are supposed to be references or callbacks to previous Fromsoft games?

I just wanted to compile a large list and see how many I can think of. From the obvious ones:

Valiant Gargoyles - Bell Gargoyles

Godskin duo - Ornstein and Smough

Omenkiller with dogs - Capra Demon

Then some others which may not be as obvious but could be callbacks in some way?

Rykard - Yhorm the giant (mainly that you need to use a specific weapon to beat him)

Fire Giant - The Last Giant from ds2 (he rips off one of his limbs in phase 2, and is the last giant of his kind)

Radahn and Miquella - Lorian and Lothric (mainly how the older one is on the other's back and does magic spells while the other is physically fightng you)

Which others could you think of?

(I've only played DS trilogy and Elden Ring so I wouldn't catch any Sekiro or Bloodborne references)
