I'm liking the new characters so far. I can see them being way more psychotic than the previous crew though. Rex only gives a shit about the princess, Basil is a murder sex bot that wants to kill everyone, and Luna appears to be stone cold about murder if it results in research. Artemis is a lot more positive but I'm not sure she'll be much better, especially under Rex's tutor-ledge.
It'll end up hilarious regardless though... And we've seen how characters can change drastically from season 1.
An idea for Eugene that could be interesting. Would be fun to see Eugene have regained control of himself and is now living as a giant slime planet with a ditto face.
Where as Mother Slime sent off groups of slime's to gather "material", Eugene could send out singular Eugene's to make money; Allowing Eugene to fulfill his wish to be the richest slime in the galaxy.
Could work with Rex's stunt too... where rather than recalling a past interaction with Eugene, once per session he can go into the back room of a seedy bar to talk to the planets resident mini Eugene, rather than making up some random information broker.... There's just Eugene's everywhere.
