Here is the extreme tron creeper. He will kill you in an explosion of light.

Creeper's were in extinct. That's the year 2068, in that year a group of player's captured a creeper and a noob to test on. They fused the creeper and noob with dye's and glowstone. The outcome was the tron creeper. For years the player's did test on the tron creeper and finally after 7 years they created the Extreme Tron Creeper!
And the creeper blowed up happily ever after!
