So I got an idea while looking at Bosco's Mecha Knight and later fighting the Collector: How about we make a gigantic friendly mecha knight that delivers supplies to Vaelyn and friends? However, he's pretty much a walking tank without a cannon. That's where you come in.
You gotta escort him all the way to the Core Terminal from Emberlight while keeping in mind that he'll die over time because of the shock he inflicts. He carries one of those mega supply boxes on the back and I guess it would be quite logical to put it the day after the supply pack delivery mission pops up. You can pick an arcade gate yourself, however you can't pick the gate with FSC in it just because. At the Clockworks Terminal, his health is fully reset and he cannot shock himself anymore until the next level.
Also, just because I feel like, make the Mecha Giant cower in fear when next to enemies. Elephants are afraid of mice, right?? Right?? Additionally like the Impostoclaus, make him shout stuff when he's hit. The Mecha Giant can also poop out oil when he's scared.
