Bert

Bert was a traitorous member to Sesame Street...he was Rank XI in the organization. He wielded a scythe and the power of flowers, because he was very girly. For some strange reason, his flower attacks were highly lethal.

History
He was the lord of Castle Honeydew. He decided to bring his buddy Ernie with him so that they could plot the death of Elmo and seize Organization Sesame Street XIII.

However, Miss Piggy, Oscar, and The Count would also visit the castle in order to investigate. They had been assigned by Elmo in order to do so.

Realizing that Miss Piggy was learning about his conspiracy to assassinate Elmo, he decided to have Miss Piggy fight Sora to the death, hoping that she would lose and vanish into ice and darkness. However, Miss Piggy chose to send Sora to Twilight Town in order to discover his nobody Roxas.

Since Roxas could kick his butt with his eyes closed (since he had two freaking key blades), Bert sent Rosita to murder Miss Piggy, who roasted her into delicious bacon. However, the bacon was rather cold, so she had to heat it up first. Luckily, for her, that was rather easy.

However, shortly after Miss Piggy's death, things would start to go wrong for Bert. Rosita broke the vials that he was using to brainwash Sora. This aggravated Ernie and he decided to stab Sora to death with his knives as well as electrocute him to death.

However, Ernie ended up being brutally murdered by Sora. This left Bert alone to carry out his megalomaniacal plans.

He decided that he would seize Sora's heart for himself so that he could take his key blade.

He later returned as a member of the Barney Gang.
