Well known characters who have a lot of toys already (examples: Optimus Prime, Megatron, Starscream) Obscure forgotten about characters who have only one or two toys to their name (examples: Punch/Counter-Punch, Dion, Flak, Banzai-Tron, Skyquake, Thunderclash, Weirdwolf) Fiction only characters who have never had a proper toy before (examples: Elita-1, Alpha Trion) Brand new characters who have never been seen before and likely never to be seen again (examples: Landshark) Me, I would go for obscure forgotten about characters and characters only previously seen in the fiction. I get a kick out of seeing someone who hasn't had a toy in twenty years to get a new toy (even if the new toy is just a repaint). With brand new characters, there's little or nothing connecting me to them. I've not read the Wings of Honor comic but Landshark is just a new character for the sake of having a new character it seems. He has no history and could probably have been replaced by an existing character and fulfilled the same role. Brand new characters are only okay when they fill a unique role that nobody else could have filled. Although Shattered Glass characters are mirror versions of the regular characters, I still consider them versions of the regular characters. Optimus Prime, Megatron, Bumblebee, Starscream and others; all have a lot of toys already. The SG concept worked well and I like what few stories I can read of it but using such high profile characters is not something I want them to do often. Botcon 06 was okay though. Despite the characters being well known, it had been a while since many had gotten new toys so I didn't have a problem with them. Besides, they all had vehicle alternate modes so it made them fresher than if they had been repainted from toys with a similar beast alt mode that they had in the show.
