[Switchblade]

For the Showa era, I have to go with Archbishop Wing from V3. Like his predecessor, Baron Fang, he was only around for six episodes. But while Baron Fang had a great design and was highly memorable for his creepy voodoo theme (and random tuxedo), all Archbishop Wing had going for him was a bunch of episodes with recycled plots from the original series. His design was bland, his character wasn't memorable, and he really did nothing but keep the Destron general seat warm until Marshall Armor showed up.

For classic Heisei, I have to go with Kai, too. His goals are incredibly vague, he spends more time making funny faces than doing anything, and he never really felt like he actually belonged on the show. I suppose the Imagin needed a leader, but they didn't deserve this useless nutjob.

For Neo-Heisei I'm actually having a hard time picking between Maki and Gamou. As I've always maintained, Doctor Maki is not a credible threat. Yes, he's sick and twisted; yes, he has very dark ambitions; but I just can't take the man seriously when any time his little doll falls over he starts rolling around on the ground and having fits.

Gamou is at least more serious, but what he makes up for in demeanor he seriously lacks in motivation. Gamou spends the entire series sitting in a chair and trying to gather the Horoscopes. Why? Well, for most of the series we don't know - there's no clear endgame for him until the last couple of episodes, and that involves an incredible ass-pull that comes right out of nowhere and never really makes much sense. Compare that to Wiseman on Wizard; his true goals are cloaked for most of the show, too, but now that things are coming to a head all of his actions are starting to make sense and you can go back and see precisely what he was doing and how it affected what happened.

I guess I have to go with Gamou. Maki may have been ridiculous, but at least there were some good ideas underneath the stupid exterior.
