Jak could stop time and meanwhile, the rest of his team could simply take the Master Sword, kill Ganondorf, and finish all the others. I'm not sure about Kirby though.
Don't forget about Ratchet. Aside having several versions of the RYNO, he also has the Groovitron. That means that the enemy whoever Ratchet throws it at starts dancing uncontrollably. Which means total vulnerability. And Clank, as of A Crack in Time, possesses the skill to manipulate time too. How about that for some backup?
