I've already done this alien before, but only with Windows Paint!
But I wanted to draw all my self created aliens again, better quality and with showing their special powers.
This one is Crabshell, the 2nd alien of my own Ben 10 aliens.
It's from an waterplanet, so it's hydrophilic and not used to walk on land that much.
By pumping water into it's body, it can use it as a jet or even a water gun.
It's armor is so hard, nearly no physical attacks can deal damage to it.
I do not own the rights on Ben 10 or any character, but I own the rights on this drawing and on this alien. So please ask me, if you want to use it!
Enjoy... or not
