Lin's Father?

It's obviously Bosco the bear...

Or is it the Denver Broncos

Momo.

Obviously Toph was bored one day and saw that Katara was enjoying spending time with her kids. Jealous and wishing to prove her superiority of motherhood, Toph summoned every ounce of strength she had to make a Giant rock penis, which she had sex with. Later, when people told her this was a stupid idea, she kidnapped a random earthbending baby and raised it as her own, claiming that her daughter was part rock, and the greatest earthbender ever (besides herself). SUDDENLY EPIC PLOT TWIST LIN THE ROCK BABY IS AMON'S SISTER WHO HIS PARENTS THOUGHT WERE KIDNAPPED THEN THEY WENT TO PAY RANSOM AND GOT KILLED BY RANDOM FIREBENDERS AND ROCKS FALL EVERYONE DIES BECAUSE STUPID METALBENDERS FORGET NTHEY CAN EARTHBEND WHILE FIGHTING MECHS!!! Also, platinum isn't that great of a metal. Especially if they had just crushed it with giant earth pillars. And thats how I got my cutie mark. Tune in next week for a story about Oranges. spoiler alert they want to kill you

The Boulder was not conflicted with tearin dat ass up

i think it was appa

<--look at that sexy beast

Pfft, Lin was probably the baby of a one night stand because TOPH DON'T GIVE A FUCK.

Then Toph raised her as a great, single mother.

Don't care who the father is.

I don't think toph knows either. She is blind after all.

its most likely a male of some sort.....

BOOMI

Toph fucked herself and got pregnant with her own sperm
