Nope. He is just a mechanic.
Probably, I always thought it was a possibility. He'd probably end up breaking it more often than not though.
And what if Upgrade covers the omnitrix on it and hacks it ?
I think he can't do it .
In theory Upgrade(or a powerful Galvanic Mechamorph since I doubt Upgrade can do it to its own Omnitrix) could go onto an Omnitrix, but I'm not sure what it would add that the Omnitrix couldn't already. Manually launching the defense mechanism as incredibly powerful blasts, maybe.
Many uprig can but not jurryrig
I don’t thinks so as it’s a piece of galvan technology and most of its species are in mechanics or motor engineering,cuz if he could upgrade it then Ben would have used him to do something with the omnitrix.
Upgraded already upgraded the omnitrix in the reboot
What do you think?
