It’s the second season of your show, and a new group of evildoers has shown up to challenge your heroes. Despite spending all last season training and defeating the legions of evil, they get creamed — uh oh, they forgot to account for the Sorting Algorithm of Evil. Using those same old moves again? This phenomenon ensures that by the second episode of the second season, somebody’s bound to get a power-up, and that any attacks learned before that power-up are worthless. This is a necessary consequence of the Sorting Algorithm of Evil, but an awfully predictable one.
Extremely common in magical girl shows, as their attacks seem to be much more rigidly defined than other genres. Magical girls’ new season powerups are often accompanied by new outfits — almost always nearly identical to their old ones, save with a Frilly Upgrade. When applied to a Post-Script Season, results in Plot Leveling. A variant occurs in video games, where early weapons like pistols become less useful as heavier firepower like machine guns and explosive devices are made available to counter the increasing protection offered to opponents.

This happens every time a new Big Bad is introduced in Dragon Ball. One major exception is Tien’s Solar Flare. First appears near the end of Dragon Ball as an effective means of showing I Am Not Left-Handed, all but disappears by the Cell Saga. The idea of training in weighted clothing was replaced by training in artificial gravity chambers. Goku’s Kaio-Ken technique is almost never seen used by him after the first season, and his transformation into a Super Saiyan had all but obsoleted Kaio-Ken.
The Super Saiyan transformation itself goes from legendary and exclusive to being shared by a handful of individuals at once, and nearly all of them have access to ascended stages beyond the standard grade. After ascending to godhood, they perfect their basic Super Saiyan forms and no longer need Super Saiyan 2 or 3. They can also merge their Super Saiyan forms with their god powers, creating a Super Saiyan Blue, which is basically a more powerful and stable version of Super Saiyan God. This may only apply to the more evolved Universe 6 Saiyans, however. Even though they can fly at breakneck speeds and don’t really need it anymore, Goku and his family continue to use it. Interestingly, the Kamehameha only gets stronger as the show goes on despite being the first energy technique used.
For Ichigo, his Shikai is useless as soon as he learns Bankai, and said Bankai is practically useless on its own after the arc where he first learns it as well. Grimmjow: You use your Bankai and all it gives you is average speed? Ichigo manages to surprise Ulquiorra with his Hollow Powers and nearly blows up the room using his Getsuga Tensho. Ulquiorra can’t even block it and gets caught in the smoke it makes. Yes, it would appear it was. In the last arc, he finally learns a new technique which is simply two of them at once.
