Armageddon boss

An extremely powerful boss, high in both stats and specials, many won't survive this.

Specials
Yes, I'm having to use bullet points for the amount this has!
 * Ability to spawn creeps when traveling, happens every 2 seconds. (-.25 seconds for every difficulty level).
 * When it dies it spawns a group of creeps, intensity is defined by difficulty stage.
 * It can fire a beam; this slows down towers by 10% (+10% for each difficulty level).
 * Also boasting 2 High powered machine guns (3 at mk2+, 4 at MEGA+).
 * AND able to fire a beam that slightly repairs other creeps.
 * AND If it destroys a tower/other item it has a 3% chance to convert it to his team, so it fires at your turrets or whatever its effect is. (Gains +3% chance for every difficulty level))
 * ALSO has a shield that can absorb some more firepower, if its not hit in 3 seconds the shield starts to repair (although the internal damage stays) (-.25 seconds before regen for every difficulty level)
 * TO TOP IT ALL OFF, Takes 10% increased effect from beneficial (to the boss) effects, and 10% less effect from harming (to the boss) effects (gains 10% for each difficulty level)
