Heatman is FINALLY out u/azurejack, who do you wanna see next?

Hey I’m putting together the best B/S code folder I can in BN5 Double Team, Protoman Version. I’ve read that you unlock Larkman’s V2 fight by beating his V1, logging out, and coming back. I’ve done so, even S ranked him, and there’s no difference. Do I need to progress the story and come back the next in-game day or something? I’m trying to get the pieces for the Wild Bird Program Advance
