The wall of bricks!!

I use a mixture of zerglings and hydralisks to attack the wall.
All burnt. Pure phailz on the attack.

I use the Fire Staff to transform the clock I got smacked with into a papulatus
Pap is not fire based. You did summon the bombs, as those are fire based.

I use Change of Heart from Yu-Gi-Oh to take control of the Stormbreakers. I order them to attack (using their electricity attacks) the wall that is wet since it was hosed down. Only one Stormbreaker does so. Wall is lit resistant. (-10 HP) They return to original owner.

I activate my trap card!
Trap activated. A large pap bomb spawns, and if it blows, everyone and everything except the wall is screwed. Luckily, it is stationary.

I build evolution chambers on ClawofBeta's creep and research upgrades for the Hydralisks and Zerglings.
Bear in mind these chambers must be above the "ground", as digging under will kill you and them.

I morph sunken colonies and spore colonies to defend the hydralisk den, hatchery, evolution chambers, and spawning pool. I also morph my hatchery to a lair so you can upgrade further.
Sunken Colonies are destroyed due to Nowhere's "glitchery". Some of Pap's bombs blow up the den. Everything else is left as is.

I fire layzors.
Stormbreakers block layzors. Being lit immune, they win.

I upgrade further.
You upgrade further. Since I only know basics of Starcraft, you'll need to fill me in on that one.

I also hire a team of Taurospears to drain the moat, and if that is successful, to attack the wall. Taurospears have 18k hp, are poison-immune and fire-resistant, and take little damage from the moat. The job offers them great pay and benefits, and they have pledged absolute loyalty to me. They have access to a large supply of construction tools.
Stormbreakers take them on. They are stronger, and as Taurospears are not lit resistant, they are taken down. they do kill 2 Stormbreakers, though. (SB HP= 5000)

I also summon some Weapon and Magic damage Cancels, a la Monster Carnival, to protect all summons on our side.
Applies to bombs, too.

I drain the moat with an invicibile Drainer (Nothing can destroy it.)
A bomb blows it up and makes it malfunction.

I get 500 People to simply throw bricks and hammers at the wall.
They manage to knock a brick loose. (HP -5)

This is the best place to use a successful IMPROVABILITY DRIVE.
Wall HP returns to the standard 1,000,000. The wall also gains offensive skills. These will be revealed as time passes.

~The wall uses Dispel! No Cancel Bonuses for you! >.>
~Wall drops an enormous brick on the Zergling camp. Goodbye to the spawning pool and Spore colonies!

Stormbreakers=5000
Wall HP= 1,000,000
Other characters, effects, and objects:
~Nowhere. dfehrfbsbja.
~The wall is 4x its original thickness and has been reinforced with steel and magic enchantments. (+200 wdef, mdef, and avoid)
~A moat filled with butane surrounds the wall. The moat is on fire/ has molten glass, spreading aerosol poison to those who come nearby.
~The wall has been hosed down and is fire-immune.
~The wall has been struck with a lightning zapper, making it lit resistant.
