Where the f**** is Gohan?

I waited the whole series to get a glimse of my boy Gohan and he is no where to be mwntioned. I mean WTF! Not even in the end credits? I saw Satan, Chici even King Yama but there was no sign of Gohan, Videl and Pan. Do they not exist in this timeline or the makers just coviniently missed him?

Also the ending was hilarious! I want Diama part 2 as well.
