You're viewing the these images and thinking to yourself "I've never seen that stuff happen in the Dragon Ball manga!" Well you're right, you haven't. No it isn't a new work by DB creator Akira Toriyama, but it's the work of Gogeta Jr. and Salagir, two harcore DB fans. Dragon Ball Multiverse is a fan manga, taking place 20 years after the events of of Dragon Ball Z.
DBM is an excellent fan made manga. I should know, I just spent the alst hour and a half reading the first 119 pages. The art is so close to Toriyama-san's that you'd almost think he drew this himself. The manga is filled with many of the over the top DB fighting elements you've come to expect from anything baring the DB name.
As the title suggests, there are multiple universes in this manga, meaning there's more than one Goku, Vegeta, etc. It can be confusing at first but once you start reading, you'll get to sucked into to care about keeping track of who is from where.
For my money, this is easily one of the best fan projects to ever come out of DB. If you're a fan, you definitely need to check out DBM. I think you'll be pleasantly surprised.
