Link breaking out of the Evil Jar in "The Missing Link" by mugging a nearby Stalfos (that was about to steal his hat) for a bomb, blasting out, and shield surfing back over to Zelda and his sword.
Zelda being an Action Girl, wielding boomerangs and a bow. Her archery skills later became canon.
At the start of "Kiss'n Tell", she takes on a Gleeok armed only with a basket of fruit.
In "Cold Spells," Ganon imprisons Link in a jar that his sword beams can't break. Spryte saves the day by using her magic to dissolve it, and attack a Gohma that was trying to eat Link.
"Sing for the Unicorn" introduced a female warrior named Sing, who rode a flying unicorn and wielded laser-shooting sais in combat.
Spryte kissing Link to save him from his frog curse in "Kiss 'N Tell."
"That Sinking Feeling":
An army of Tektites web Zelda up and rob Link of his sword, then pounce on him. He defeats them by throwing the Tektites biting him at the others, knocking them back into the Underworld before zapping the last one with his sword.
Link's fight with a Darknut is pretty cool, as it's one of Ganon's most competent soldiers and we actually get to see some swordplay out of Link.
In the same episode, Ganon uses magical chains to subdue Link as he pulls Zelda and the Triforce of Wisdom towards him with a spell. Link uses a Power Bracelet won earlier in the episode to break free, wraps one of the chains around Ganon's wrist, and throws him out of the Underworld.
Even Ganon, of all characters, has one. Already aware of PrinceFacade's presence, having dealt with him before, Ganon exploits his true colors by having Zelda kidnapped and carried through a muddy swamp. You might say Ganon just did Zelda a big favor by exposing Prince Facade for the vain braggart that he is, especially while Link had spent a great deal of the episode envying him, completely unaware that Facade cared more about his looks than Zelda herself.
When Link comes back to inevitably save the day, he manages one by showing Prince Facade how a real hero does things, walking through the mud and curb-stomping the Zora that captured Zelda.
"Fairies in the Spring" shows the Fairy Kingdom protecting their home by conjuring up beasts made of water to give Link and Zelda a tough fight. This really needs stressing: fairies underwent Adaptational Badassery! Bonus points for the show being made years before Ocarina of Time introduced Morpha (not to mention unlike Morpha, this magic doesn't really have an exploitable weakness).
