Activating the Confidence Mode changes a few things in Krillin's gameplay.
- Upon activation an empty Confidence Bar (bottom bar), a full buffer bar (on top of that) and a Krillin head are added to the screen.
- His forward walk becomes faster, while his backwards walk becomes slower.
- Ground Forward Dash becomes a more standard traveling dash instead of a tiny spurt.
- Ground Backdash is turned into a fast smear and refills a small portion of the buffer bar.
- Air Forward Dash can be cancelled before the dash animation ends.
- Faster recovery after a Jet Kamehameha (only the first one in a combo).
- Gain access to an additional Rocketman in the same jump (now able to do any combination of two regular ones and two EX ones).
- Able to throw a second and third Destructo Disc by pressing any Punch button two times after throwing the first.
- Gain access to the Senzu Bean (detailed below).
- Solar Flare x100 costs Lv2 instead of Lv3 and cancels the Confidence bar.
- Performing Fake Special Moves, Duck'n Cover, Mirage and Wild Sense Follow-ups fills your Confidence bar.
- His non-EX Wild Sense now acts identical to the EX version, but using his buffer instead of his power bar.
- Performing both the additional Rocketman and Wild Sense (except the EX version) stance takes a small portion of the buffer bar. Extra Distructo Discs take an even larger chunk.

The Senzu Bean acts as Krillin's install exit move. He pops one of those beans in his mouth, refilling his health instantly. The farther your Confidence bar was filled when activating the Bean, the more health you'll regain.
