Jack constantly says he is better than everyone else on the team, but he is actually no better than any of them...
A general or admiral, because of the busyness of his command responsibilities, doesn't have any time to train with his incredible power. He ends up being Unskilled, but Strong and Weak, but Skilled opponents can defeat him.
On the verge of defeat, he pulls out a new Super Mode strong enough to overwhelm his opponent's skill.
Parodied: Besides fighting, the leaders of Super Awesome Team can't do anything normally, leading them to break everything or make conventional tasks into a show. The members of the team will either not realize that they shouldn't smash the table nor utilize their combat training to scramble the eggs, or simply sigh and carry on.
Zig Zagged: Jack constantly says he is better than everyone else on the team, but he is actually no better than any of them, until you press his Berserk Button, but he turns out he still isn't much better than the others, until you press anotherBerserk Button...
Averted: He is equally strong as the rest of his team.
Enforced: "We need to make the higher-ranked ones stronger, otherwise they'll be too easy to kill!"
