Gotenks gets cocky! He transforms to Super Saiyan 2 and gets buffed up! EX Ghost Fire now requires no Super Bar to perform. And as expected, SSJ3 Beatdown costs LV2 instead of LV3 (but you still get a full LV3 power bar that acts as your SSJ3 timer) and gets Finisher at the end of it.
-You gain two bars; a Power Bar (top, yellow) and a Finisher bar (red, bottom). you can actually gain up to 3 additional Power Bars. So if you just keep powering up, combined with your default Power Bars, you can get up to 6 full Power Bars.
The Finisher bar manages which Finisher will be played once you've managed to knock the enemy into the Dimensional Portal in SSJ3 Mode. This Finisher bar fills up by doing specific actions:
-Being in Hero Pose.
-Being in Spin Spin Pose.
-Taunting. Taunting while having Ghost Bros gives a greater amount!
-Performing Insults.
Speaking of the Finishers; they are as follows:
LV1 - Big Tree Kamehameha
LV2 - Bro Force
LV3 - Super Best Final Cruncher Attack!
Portal will do a LV0 ender attack if he is not in SSJ2 or doesn't have at least 1 Finisher bar. Unlike any other character, Gotenks remains in his SSJ2 Mode after performing his Finisher.

Even exiting his SSJ2 Mode is done in a flashy and entertaining manner! Take a seat, Dan! By performing this Exit move, all current Finisher Bar filling will be converted to Power Bar.
