Something I've been giving a little thought recently is that whatever non-upgrade form a Rider doesn't use much in their own series; it tends to be their main go-to in later movies almost as a way to 'make up' for it.

For instance, OOO infamously couldn't use Gatakiriba much due to the expensive CGI; it got used only about 3 times. But then in the movies? It of course got featured along with all the other combos in Wonderful and Mega Max; with the former even having Eiji use his duplication power for the final fight gimmick. And then in Heisei Generations Final, it's the only combo he uses aside from Tajador! And in addition, what OOO form does Grand Zi-O summon for his first finisher? That's right! Bunch of green bug boys!

In a similar vein, and one that I realised is a bit odd... Decade Hibiki. Tsukasa used this a grand total of ONE TIME in his entire series -- the very first episode! And then after that, it's 'made up' for -- he uses it against Amazon in All Riders vs. Dai-Shocker; it's one of his chosen Kamen Rides against Captain Marvelous in Super Hero Taisen; against Fifteen in Kamen Rider Taisen; and then against Sougo and Geiz in his Zi-O debut!


Are there any other things like this that come to mind? Where one of the initial power-ups is barely used by the respective Rider if at all in the original series, but then gets used all the time in their post-series appearances?
