Supersonic Sue, an old foe of Boss Awesome, has come to San Fransokyo seeking one more shot at her old rival.
Tropes:
- Antagonist Title: Supersonic Sue is the Villain of the Week.
- Big Damn Heroes: Boss Awesome shows up to fight Sue and Steamer after they've managed to disable Big Hero 6.
- Big "NO!": Baron Von Steamer lets out when when Boss Awesome tells him who his real number one enemy is. Baymax then lets out one because he's loopy from a low battery.
- Borrowed Catchphrase: GoGo gives an "Oh no" when Supersonic Sue decides to test the endurance of Baymax's overdrive mode. She also borrows "Supersonic sue me, why don't you?" when talking with Sue near the end.
- False Friend: Richardson pretends to be warming up to Fred so Fred will let him into his house, allowing Richardson to steal Fred's Captain Fancy underpants.
- Ham-to-Ham Combat: The titular villainess and Baron Von Steamer have an Evil Laugh contest.
- Logic Bomb: Mini-Max becomes a victim of that in the end the episode.Fred: It's like my dad says: a real hero helps everyone in need. Even his enemies.Mini-Max: Help an enemy? You have blown my mind! Ha-ha-ha! I am in need of repair.
- The Nicknamer: Supersonic Sue has a new nickname almost every time she addresses one of the team. (ex; Skater Tot for Gogo, Laser Paws for Wasabi, etc.)
- Oh, Crap!: This is GoGo's reaction when Sue decides to test Baymax's stamina in Overdrive mode.
- The Only One Allowed to Defeat You: Sue pins down Boss Awesome, but Baron Von Steamer attacks her because he doesn't want to be upstaged as Boss Awesome's Arch-Enemy.
- Pet the Dog:
- Even though Supersonic Sue boasts that she's superior to GoGo, she admits in the end that she came out of retirement because she was inspired by seeing GoGo on the news.
- Fred lets Richardson keep the Captain Fancy underpants because he sees that Richardson is just a lonely kid using collectibles in place of actual friends.
- Sympathy for the Devil: More like jerk, but Fred allows Richardson to keep the Captain Fancy Underpants he stole because he realized he has no friends.
- Waking Non Sequitur: When Big Hero 6 tries to get answers from Steamer, they find him asleep at first, but he doesn't take long to wake up, though.Steamer: GIVE ME BACK MY PUDDING!!
