The Feet Fighters are one-shot villains in Wander Over Yonder. They were Admiral Admirable's minions.
They're anthropomorphic alien humanoids who helped Admirable in his conquests. They're Fist Fighters's notable past counterpart because they appear to be feet with bodies and wear yellow, pistachio green, and white bodysuits with an "A" on them, unlike his present counterpart who appear to be fist with bodies and wear same bodysuits but with blue, purple and white tones.
Wander and Sylvia found themselves on a planet to fill up on orbble juice, but accidentally filled up on time travel juice. This accidentally propeled them into the past–specifically, the show’s pilot, “The Picnic.”, when, in the constellation of the Celestial Galaxy, there was a battle between Lord Hater, commandeering his Watchdogs army, and Emperor Awesome, commandeering his Fist Fighters army to see who will receive one wish from the visiting celestial being during the aligning of the planets.
Thereupon, Wander and Sylvia tries to back to their time but are lost. In their first tried they travelled until events in "My Fair Haytey", when Hater was singing for Dominator. In their second tried Wander runs so mucho into the orbble juice that they arrived until future events in "The Search of Captain Tim", when Hater and Emily Ripov were about to be devoured by the Arachnoqueen.
In the past when come Wander and Sylvia by Orbble Time, there is a similar battle between Major Threat, commandeering his Watchsquids army, and Admiral Admirable, commandeering his Feet Fighters army to see who will receive one wish from the visiting celestial being during the aligning of the planets.
Wander and Sylvia travel to a less remote past where it is shown as both knew themselves. In her dark past, Sylvia was a bounty hunter and found Wander after a fight against Killbot 85. Both enemies tried to catch Wander (althought it is unknown if both were or not hired by same person who is unknown to). After a fierce battle between them, Sylvia ended destroying Killbot 85 and bailing Wander.
In another tried to back to their time, Wander and Sylvia travels, literally, until the end of the WOY Universe. Scary, both went back in the time but ran so fast that they arrived to the beginning of the WOY Universe. Thereupon, they travel to the orbital station fifty years after their time and both ran out of juice one more time. But, without they knew, their future selfs changes them the juice in order to restore the time in despite that meant get out of existence. And then, recent Wander and Sylvia back to their time and their future selfs dissapear.
Like their rivals, the Watchsquids, and Admirable, it is unknown what happened with the Feet Fighters. One possibility is that they were still working with his leader in conquests and another possiblity is that Admirable died for natural causes and they became independent.
