SIMD (standing for Suck It MUGEN Database) is an original character with the sole purpose of making the editors of the MUGEN Database "rage", as stated in the ReadMe file included with the character.
SIMD's idle animation is made up of eight different layers of animation in order to make it difficult to extract as one whole animation. Seeing as the MUGEN Database puts the animated idle pose of a character in the gameplay section(s) of a character article, the creator of SIMD (GozioLog) made it so this (in his/her mind) couldn't be done, though has been proven wrong, as shown below.
In M.U.G.E.N, as stated above, SIMD has been created by GozioLog. The character lacks any form of sound file, and is made up of very simple, unshaded sprites.
Blatantly made on the basis of being a hindrance rather than an actual character, SIMD lacks any form of collision hitboxes (aside from the ones on his "Death Sphere (Inner)" projectile), thus rendering him invincible to regular characters. He cannot move, jump, nor crouch, and his only form of attack is an automatically activated, cheap, projectile-heavy attack that fires the aforementioned "Death Sphere (Inner)" projectiles at 0, 45, 90, 135 and 180 degree angles and surrounds SIMD in a purple, sphere-like projectile. Due to the aforementioned lack of collision hitboxes, only certain characters like ONI-MIKO-ZERO with complex coding specifically designed to deal with such characters can defeat him.
This character does not have any special or hyper attacks.
This character does not have any palettes, and as such, runs off the palette of sprite 9000,0.
