Even Mercury is a decent character in Chibi.
Heh. Flan.
Oh that reminds me next Volume he starts being voiced by Yuri Lowenthal.
Actually Volume 3 is when they start getting a lot more professional voice actors.
On that note, there is another VA change next volume, to anyone who's new to the series.
The show ran into a hiatus pre-production on Volume 3 after Monty Oum, the show's creator, passed on during a surgery. Eventually, given the resources he'd left Miles and Kerry - the other two writers who worked with him, Rooster Teeth continued with RWBY production for Volume 3.
There is a sporadic change in some of the choreography of the fights from this point on, as anyone who is aware of Monty's work online, fast paced action was his signature, and one of RWBY's most recognisable traits since the first trailer. A couple of key fights, that'll probably be highlighted here and on Twitch chat, will probably signal you to spot what fights he'd worked on before his death.
The other reason I bring this up is Monty was the VA for Ren on team JNPR. Following his death, Rooster Teeth reached out to Monty's brother Neath Oum, and he's been cast as Ren ever since.
There's a lot of send-off imagery at the start of volume 3, and them casting Monty's brother to carry on his own role within the story is pretty touching.
