re: Hidden Potential Activation

the long way,  first , go to your HIdden Potential Activation sub-menu in-game, learn/study and understand the general idea. second, visit Hidden Potential Activation and Skill Upgrade System. read and study those, plus some of the tips shared in the comments. third, visit the Grim Reaper of Death's Rampage SS3 Gotenks page, and read some tips shared by other users who have the card.

basically, if you have max SA level, and you have at least 1 Dupe (duplicate), open the Roadblock at bottom-right Route. if you currently don't own any Dupe, open the top-left Route.

there are 4 Routes, top right, top left, bottom right, bottom left. each Route has 1 Roadblock. each Roadblock can only be unlocked/opened with 1 Dupe (duplicate of the same exact card).
