Notes:

Super Dragon Ball Heroes Chapter 12 of the main story
Super Dragon Ball Heroes Parallel Chapter 17 the other being the Chapter 7 of Universal Conflict Saga
Super Dragon Ball Heroes Chapter 1 of the Dark King Mechikabura Saga

So complicated to keep track of this. Now there are like 3 side stories excluding anime adaptation and video game adaptation of SDBH

I like the Heroes manga, so I hope they do justice to Gogeta Xeno vs. Dark Gogeta. I think Gohan Xeno will turn SSJ4 next parallel chapter.
