Use Heroes to improve flight, but compare the numbers shown in your game
The target game's Roblox description confirms the Hero system and its general purpose. It does not identify individual Heroes or publish their values.
Unlocking a Hero is part of the progression loop: fly through levels, earn Wins, and improve the stats that help you travel higher and farther. Until a current target-game roster can be checked, use the in-game Hero screen as the authority for names, costs, rarity, and bonuses.
