Why is Heihachi's hair black in Tekken2?

And he has white hair in the other series?

He didn't want accept that he's old.

Was he stronger back then when his hair was still black in Tekken 2??

Probably. When your hair loses it's color it means you're getting older, tus weaker.

Heihachi was in his late 40s early 50s during Tekken. During Tekken 3 he is in mid 70s so yeah.

Maybe age had something to do with it? IDK just a possibility.

Seeing as he was still able to destroy Jack robots with his fists then I wouldn't say he hasn't been severely weakened.

To be honest I think he has gotten stronger with time.

That too.

Does it really matter? At least he has hair.

Hair dye?

It's called getting old, your hair goes grey...
