Update of the site!
Update of the day on DBM website:— Comments: On "Reply to" and "Edit this message", the button now changes and sends you to the form.
— Comments: "Spoiler" button wasn't working on the profile page, now it does.
— Swipe was added to change of page recently. Now it's working only when the comic page is actually showing.
Some fans speculated that Gero saw Trunks kill Freeza, and seeing that much power, decided to make his cyborgs stronger. It's wrong because Gero didn't know about SSJ when Goku transformed in front of him. So he didn't see the fight against Freeza.
This page gives my personal explanation. In fact, the cyborgs are weaker in the future, because they are 20 years older and are worn-out.
This explanation is DBM canon, but nothing supports it (nor contradict it) in any good DB source.
