GekiViolet and AbareBlack are counterparts while AbareKiller and GekiChopper are counterparts... I'm not sure why Gokaiger chose to have Gekichopper as a core team member. It could have very well been that they knew there was a physical limit to the GokaiCellular's design and having one extra button on the device would have been overwhelming. Not that it'd have stopped Gai transforming into GekiChopper if it was considered his counterpart though. Probably because there was no unofficial counterpart in Gekiranger for Ahim to use (unlike Abaranger, where they had AbarePink). Thus, they made GekiChopper a core team member. But while you are correct that counting Violet as a 6th is not quite true, it doesn't mean that Chopper should have been a sixth either - it may have been Toei's intent all along to not have a 6th. Kakuranger had no 6th, but its two predecessors did.
