[ASM & Hex] How to add Parental Bond to FireRed

Hey everyone, I'm new around here and would love to learn how write my own abilities. I've been reading up on ASM and battle scripts for the past couple days, but I am still not confident enough to begin to write anything of my own. I really want to implement the Parental Bond ability into FireRed. Could anyone supply me with the code and possibly explain how it works so that I can better learn how to do this myself?
Thanks in advance!

Dang, wish someone could help me out with this

I understand that it is probably really difficult to do and really complex

But, I have ideas. I am inspired. I am eager to learn

Parental Bond is such a cool ability! Wish Kangaskan had it all along, even before Megas — even with the nerf, it's quite viable.

I'm not much of a coder, but would love to learn together and collaborate on this @YourFavoriteEgyptian.

Let me know!
