We never really get to spend too much time with Techno Baron, and neither with Hypno Baron so it really comes down to Ammo and Squiddie.
Regardless, I still think that they’re interesting for the screen time and involvement that they have.
Squid Baron’s dynamic by being a neutral force of good & evil to Shantae is both interesting and funny, and Ammo Baron’s the villainous oaf with a one-track mind and dumb-but-still-funny onomatopoeias.
Hypno Baron was a mysterious figure in Risky’s Revenge and while I wish it could’ve continued when they brought him back I understand that WF wasn’t really in the business of telling at least a semi deep story. Same treatment with Techie even though he also had a tiny role in Pirate’s Curse.
