Would you like a Groovitron or Morph-o-ray to exist in real life? Or maybe just an Omniwrench or Hoverboots? Or even a Personal Hygienator? (Or a crotchetizer? 
) etc.
Let's discuss.
The Omni-Wrench. Gimme, gimme, gimme!
I just love that thing.
clank with all his upgrades, altough that's not really a gadget…
groovitron, yes.
Tesla claw!
hoverboots, and of course omniwrench( Millennium 12)
If ratchet could build a space ship with just omniwrench, then yea invent that please
The Omni-Wrench, hoverboots, a set of Infernox armour and the rift ripper. I love the idea of my own personal, portable black hole storage :oui:
