This thing took a few years to build, and is the size of a small planet

After fighting Beldum, Eggyhead realized the The Collecter needed a good way to fight massive enemies. So he started working on this. With the help of Egg-Bots, and a few hundred boxes of Hot Pockets, he created the Mecha Collector. The Mecha Collector, instead of having a bunch of controls, transfers your conscious into the machine.

knifeboi: *disappointed that he couldn't help built it*

What's he saying?

It's a bit blurry

"it uh, *pant* took a while."

Collector: I can see that, but there are some improvements I can make. But the equipment needed for it is far beyond your experience so I recommend you sit down and breath for a bit

*He flies up and scans it while holding a bottle of black liquid*

*When he finishes scanning he dumps the liquid on the robot and it begins covering it entirely*

Modified venom symbiote, same as my armor but designed to cover bigger things

This will let it morph into any weapon that is needed

AND...

*It shrinks into a cube*

Portable.

Trust me, it needed this. Just a solid mech suit won't be enough to fight the devourer whenever it attacks again.

It already could shape into what you want, inside the arm is a ton of liquid metal, that can shape in to whatever you want. This thing also is portable, *presses button and the mech shrinks to a gumball size* just don't eat it.
