Unknown Virus

Well for my flash class, I'm working on my final project and wanted to make Space Invader like game.
The game story sets in the future where the entire computer system in the world got corrupted by viruses and one Anti-Virus company developes a drone and sends it to the cyber world in hope to eleminate the viruses to stabilize the world again.

This is the main enemy or more exactly final boss of the game named Unknown Virus.
Mainly because it doesn't have its own stable form, so this boss was impossible to analyze as "in game" story.
In addition, there is no origine of the boss, so in game, no one knows how it became exist or who created this.
Since it is a final boss and has unstable forms, what kind of powers or attacks does it have?
This boss is certainly the most mysterious, yet dangerous one to fear.

Inspired by Unknown boss from Space Invaders Infinity Gene.
