G1 Mirage doubts the Autobot cause (although this was never exploited in the G1 cartoon - there was one ep where Cliffjumper questions Mirage's loyalty for no apparent reason, but his doubts were utterly unproven) but Animated Prowl doesn't - he was just more of a loner in the beginning, more like G1 Snarl. But the difference is that Prowl learnt the value of teamwork by the end - and hopefully we'll see this character (and others) continuing to develop as the series progresses.

Character development was something that was sorely lacking in the G1 cartoon - for the most part, they remained static throughout, or they'll have random personality changes for one story to serve as a plot device e.g.: Cliffjumper's random aggressively hostile doubts against Mirage's loyalty... it disappeared by the end of that episode as mysteriously as it had appeared!

It's still early to tell how much character development will be in this series. Prowl's character development was similar to that of Slingshot's in "The Key To Vector Sigma" where his character evolved for that episode's story, but in Slingshot's case his character remained static after that.

I do hope that we'll see continuing character development as we saw in the G1 comics and Beast Wars/Beast Machines. Time will tell.

Animated Ratchet is a combination of at least three G1 Autobots...
