JUST THINK ABOUT IT!!!
I think when Upgrade sacrificed himself, he simply merged with the watch. And to avoid glitches or a paradoxal feedback from the Omnitrix (or just Ben upgrading it to the point it overloads and explodes), it deleted the DNA sample so there wouldn't be any error coming from the system. Just a theory though
That's a pretty solid theory. We'll probably get an explanation once (if) Azmuth is re-introduced to the series.
azmuth has already been introduced (only his voice) in closed captioning on tv if you go on alien worlds it says azmuth:bla bla bla and so on.
Sucks because Upgrade was the one alien you could do the most with. I also hate how this Omnitrix can only store 10 active aliens at once without glitching. Also stupid that Shockrock stops appearing after he can enhance other aliens, meaning Ben only has 9 aliens now.
Heres what it is an idiotic writing decision because here is why they did that they wanted to give ben a new alien but he is called “Ben 10” so they decided to have the non-sentient DNA sample sacrafice itself even though there where 2 reasons Ben is called Ben 10 1 because he is 10 years old and 2 because he started with 10 aliens.
Ben is called Ben 10 1 because he is 10 years old and 2 because he started with 10 aliens.
True, but most people forget it when he aged and got more than 10 aliens available in OV's Omnitrix. All they remember is his last name "Tennyson". I too hate how he can't have more than 10, but hey, no aliens are a one-off thing, so we'll see Gax and Upgrade again someday (maybe even Rath)
Here's a theory: Maybe, Shock Rock is a Galvanic Mechamorph's true form. So, when a mechamorph absorbs the right energy, the mechamorph turns into... whatever Shock rock is. Maybe an Electronic Mechamorph.
Decent enough theory, but doubtful that we'll ever get a proper answer given the episodic nature of the reboot. The days of serial storytelling for Ben 10 have passed unfortunately, so it's unlikely we'll ever get a real answer.
