When Red Action is called to the future for an epic battle, Enid is unsure what to do.
Tropes:
- Cannot Spit It Out: Enid wants to tell Red to stay in the present, but she doesn't want Red to think she's an "annoying, clingy nerd" so she pretends that she's okay with Red leaving and not caring about it. But by the time she's able to tell Red, she waited too long and Red is already an adult.
- Foreshadowing: When Enid enters the future, she steps on a Borg arm, breaking it. The arm briefly shows the plasma-absorbing force field, showing how it's useless against organic matter.
- Great Offscreen War: The war with the Borgs.
- I Hate Past Me: Subverted. Older!Red eventually starts to embrace her role in the Hue Troop and firmly tells Enid that she shouldn't be in the Bad Future, seemingly the opposite of her previous anti-Hue Troop perspective. However, after a decade she realizes she missed the time she spent with Enid and changes time accordingly by kindly telling her past self to not make her mistakes.
- Mundane Utility: Red Action uses her Arm Cannon to help Enid and K.O. stack bags of chips on the shelves at the Bodega.
- Rock Beats Laser: The Borgs' shields are able to absorb the Hue Troopers' plasma attacks. But when Enid figures out that the Borgs can be taken out without plasma weapons, the Hue Troopers were finally able to end the war. Apparently, none of them never tried punching or kicking them and it took them a decade or so to end the war.
- San Dimas Time: Subverted; Yellow Technique tells Red Action to hurry in coming back to the future, giving her less time to spend with Enid and KO. But after months of fighting, Red Action comes back to the present era minutes later. This repeats several times, running into the opposite problem, as Enid feels she's missing months and then years of her friend's life. Ultimately, Red decides to alter her past to delay her return to the future several years, and there's no indication she'll arrive any later.
- Sequel Episode: To "Back in Red Action", where now that Enid and Red Action are hanging out, Enid starts to worry about losing Red when she goes to the future to aide the Hue Troops.
- Set Right What Once Went Wrong: When an Older Red Action sees how sad Enid is when she regrets not telling her to stay in the present, Older Red travels back before her present self leaves for the future and tells her to stay in the present.
- Skewed Priorities:
- When Yellow Technique calls Red Action to come back to the future to fight in the "ultimate battle for the universe", Red doesn't feel like leaving due to her already having plans with Enid and K.O., which understandably angers Yellow.
- While Red Action has to fight a seemingly endless war in the future, and Enid is worried about never seeing her again and telling her how she feels, K.O. is just worried that his favorite Double Dip Lazer Chips are going to be discontinued.
- Spanner in the Works: Thanks to Enid going to the future, the Hue Troops managed to discover the Borgs are weak to organic matter. If Enid had never followed Red to the future, the war would still continue.
- Temporal Paradox: After living for years in the future, the older version of Red Action goes back to the beginning of the episode to tell young Red Action not to go to the future, causing everything that happened in the episode to not have happened at all. The characters still remember these events, but they also remember Old!Red Action telling Young!Red Action not to go. K.O. remarks that he also has new shoes somehow.
- With a Foot on the Bus: Red Action appears to have fought in the future into her old age, and even after the war ended, seemed like she'd go the rest of her life without spending a significant amount of time with Enid or K.O. at the Plaza. Then it turns out the past and future versions of Red Action decided to delay their trip back to the future for a while, turning those events into an alternate timeline.
