Hi there. I see you keep adding notes like “it is unknown if...” to many pages. This is speculation, and is generally not allowed on the wiki. In the case of Fully Charged, it’s a new series, of COURSE it’s unknown! Will the Robot Masters return after being arrested? Will Junk Man join them? No one knows, but it could very well be answered next season.
Here is when “it is unknown if...” would be something to note. Say the Robot Masters ended up in jail, and the series, despite continuing, never elaborated on them, and maybe even ended before it did. Then it would be ok to leave at the end of the page’s history section something along the lines of:
“It is unknown if Guts Man was ever released from jail, as he has not made an appearance since then.” (This would be something to note if he didn’t appear for like several episodes on end without returning)
“It is unknown if Guts Man was ever released from jail, as he does not appear again after this.”
“Guts man’s fate is left unknown, as the series ended before he could make another appearance.”
And so on and so forth. But because the series is ongoing, it’s fairly obvious it’s not known at this time. I would say because this IS a MegaMan series, and I doubt they’d just leave them in jail and never use these characters again that yes, they will return.
