I also don't believe that any Transformer was reprogrammed to switch sides, long term. By which I mean:

1) The reprogramming has to happen in the present time (the Constructicons' tale in Secret of Omega Supreme therefore doesn't count)

2) ...and then they have to remain reprogrammed for multiple episodes.

There are only two cases off the top of my head that I can think of where a transformer has switched sides and it has met this critera: Skyfire and Dinobot. And in those cases, they were not reprogrammed; they used their free will to switch sides.

It's never explicitly stated, but it seems to me Transformers have core natural identities which never really change, even if they are reprogrammed to some degree. For example, Gears is supposed to have his personality changed (in "Changing Gears") to being less grumpy. But at the end of the episode, when he wants his personality component back, he's grumpy about wanting to be grumpy! So he hasn't changed that much.

I think it's possible that even if you accept the origin story of the Constructicons in Secret of Omega Supreme (which is a tricky issue, as explained in the above post), I think a possible interpretation is that Megatron's attempt at reprogramming the Constructicons merely introduced them to the Decepticon side, and then they willing chose to stick with it. If you're of the opinion that any Transformer can be reprogrammed to any personality, at any time, well, that episode contradicts you. Because if that were true, there's no reason why Omega Supreme couldn't have successfully reprogrammed them back.


I don't like games that are fun.
