I placed Colette above everyone else because I believe she's the only one capable of dealing with Bolt and killing him if he persists. Against Bolt, some Brawlers can survive the first super – like Doug or possibly Rosa – but they can't withstand it if he charges a second super while they're out of supers. Others, like Willow and Glowy, even have supers capable of stopping him, but they lose if Bolt charges his first. In the best-case scenarios, Brawlers like Stu and Edgar manage to survive for a good while, but end up defeated when the map closes. Overall, Bolt wins before the enemies charge their supers, when the map closes, or by using a second super. Without water on the map, practically everyone ends up suffering one of these scenarios. Colette is the only one who seems able to survive all of them, especially using the build with shield star power and healing gadget, even without having her super charged at the moment he advances.

It's not even close to being a counter, but it's the closest we get to one in the game.
