Clembrane

Clembrane is a character from the Invader Zim series.

Clembrane is a failed clone of Professor Membrane created by Zim in the past as part of an aborted plan to swap him out with the real Membrane and have him ground Dib forever. Zim gave up on him, not because the clone obviously looks, sounds and acts absolutely nothing like the real Professor Membrane, but because the clone couldn't make pudding just the way Dib likes, even though Dib doesn't even like pudding. Nevertheless, Zim does find a use for Clembrane in his plots eventually.

In the XP4 fics, Clembrane debuted in the XP4 Heroes of the Multiverse.

Appearance
Clembrane wears the same lab coat outfit as Professor Membrane and has the same scythe hairstyle, but beyond that they look completely different. Clembrane is taller, and much more bloated than the Professor, his head being swollen and orange, with a stitch-mark in the middle of his face.

Also, his eyes are visible and always open (as opposed to Membrane, who always covers his eyes with goggles), and his left hand is much larger than his right. He also has a small hump on his back.

Clembrane also has a slight resemblance to Nightmare Dib as he had the same lobotomy scar on his forehead and a similar big head and mouth.

Personality
Clembrane is very upbeat and happy, albeit very overbearing. As he's convinced that he's the real Professor Membrane, he genuinely cares about Dib and Gaz, wanting to spend time with them and even being willing to turn on Zim to protect them.

Clembrane is so convinced that he's the real Membrane that if anyone tells him otherwise he throws a massive tantrum, rolling around and smashing everything in sight.

Also, Clembrane is obsessed with pudding. He's constantly shown making it, and serves it to Dib and Gaz at every opportunity.

Trivia

 * Justin Roiland was meant to be Clembrane's voice actor, with Jhonen Vasquez providing the current voice as a placeholder, as Roiland had a busy schedule and they weren't sure if they could get him. They eventually got him for the movie, but the crew had all fallen in love with Vasquez's Clembrane voice by then, so instead Roiland was relegated to the role of Foodio 3000.
 * Clembrane's creation is ironic, as there was meant to be an episode prior to the series' cancelation in which Dib was to discover that he was a clone created by his father.
 * The fact that he is a (failed) clone of Professor Membrane heavily implies that Zim somehow got his DNA in order for the cloning process to be made possible.
 * Ironically despite having an obsession with pudding, Clembrane was never seen eating any.
 * Its unknown if Clembrane is set to appear in the comics.
