Which Hunter X Hunter Characters have similarities to Ranma 1/2 characters

ok i know this is super weird and these two franchise has a lot of difference lol but out of curiosity plus i love this 2 anime's

e.g Shampoo and killua are similiar at some point like their both Kawai plus they do everything for the one they love shampoo for her love for ranma and killua's friendship for Gon in which they have certain reasons for befriending them but ending up being with them all along
