"We're under attack, No. 6 Base is under attack, requesting support."
The alarm blared in a loop, and inside a massive base, a giant gorilla was wreaking havoc everywhere. This gorilla wasn't particularly large, standing only a bit over three meters tall, and was even smaller than most of the war machines.
But this gorilla was indestructible; attacks from various weapons seemed to just tickle it, and it paid no mind to them at all.
The gorilla's every attack released a powerful shockwave, shattering even the toughest of ground combat tanks with a single blow. Buildings that were supposed to be structurally strong disintegrated after just one hit, leaving nothing behind.
Surrounding weapons and mechs were futile against it. What's more, this seemingly slow gorilla had the ability to move instantaneously, always disappearing and then reappearing in another location, each strike devastatingly effective.
