Robotman I wouldn't mind seeing again but his story is fine how it is.

Agent Kalaschnikov and Gilbert are good villains I would really like to see them again, especially considering Kalaschnikov is a female villain and those are quite rare in this show.

Evil 17 is possibly dead and Justine is not really my favourite.

Either Robotman or the Roboboys

I would have liked to have seen what would have resulted of Gilbert saying he'd "design an even better robot".

Bro ikr? The anticipation killed me back then

Oh did you watch the show back when it was first airing?

I first saw it in a rerun. I always wanted a Roboboy of my own back then because of that
