Dragonball multiverse is the one of my favorites online comics now.
I like the ideas of the tournament (it sounds like Marvel's "What if...").
btw, I was surprised the battle of Pan and Bojack (I'm not going to spoil this...).
I know other Dragonball online comic called "Dragonball AF" drawn by Japanese guy.
His artwork is amazing, but compared with "Dragonball Multiverse", he draws really slow (like 1-3 pages per a month), and besides he sells his Dragonball AF works to other people (which doesn's respect to Akira Toriyama).
I quit reading "Dragonball AF" now...
