In the lead up to the Majin Buu painting I posted earlier, I endeavored to draw all forms of Majin Buu in any official media with any actual design. I only had to count out his absorption of Broly and Cooler in one of the psp game since they just used the Super Buu model and picture. Similar to my ronin warriors drawings, they acted as assets in case I ever wanted to do a video on the character, as using stills from the anime and manga would lend my content open to content strikes and the like. I did make that video, speculating about Buu's biology.
As such I have a sort of BuuDex that numbers in the 30. It was around this time that I would transition from using number 2 pencils, to using H,F, & B pencils.
My personal top 3 design wise Innocent Buu Puar Absorbed, Kid Buu Kibito Kai Absorbed, & Majin Satan.
The Super Buu forms from Budokai 2 were a little difficult due there being no official art or game stil, so I had to pause game footage to get some references to use. I very dumbly didn't correct the graphical flub in the Frieza form so my drawing of this form has extra love handle fat.
