I thought these were just really cool…
I’d give credit, but I honestly found these just floating around. But the Marshall Lee one I found on Tumblr from mordake.
Thanks to Slackerific on Tumblr the credit for these drawings go to:
The Marshall Lee and Prince Gumball are both by Sscindyss
The Bubble gum is by Steinlo right here on tumblr.
The Marceline is by Conniiption
The Iceking is by Branflakes2
