??? Does Air make a difference? I doubt that by just eating Air, they're strong enough to take on Heracles like Blue did.
AIR is one of Acacia's dishes that even the Blue Nitro want. It's the highest level ingredient they've consumed thus far. It definitely matters. But it doesn't mean they can take on Heracles yet. But heck even Blue failed to beat Heracles, although it was on a time limit.
