[Blade Fang]

I counted some episodes about DonBrothers. So it's quite surprising about 14 episodes in DonBrothers series didn't have a mecha fight.

A human-sized mecha episodes still counted as an episode with mecha fights.

About Alters, I think they are more similar to support Robots (similar to Foodroid, Candroid, Memory Gadgets, etc) than your regular Sentai Robos.

I still quite annoyed about origin of DonBrothers'Robotaro Forms because their Robotoaro Forms origins is didn't have interesting backgrounds.

Compared to King-Ohger, King-Ohger has more interesting backgrounds about their giant robots.
