Hero packs are currently purchasable from the games' store, the initial 'Origin' Cards have an 85% chance of gaining a heroic hero, and a 15% chance of gaining a rarer legendary hero. Origin cards should be ready to redeem for heroes by Feb 15th.
As things stand heroes seem to all have individual values, or more commonly known as IVs, this means each hero will be unique, with some even of the same character becoming stronger than others:
All heroes are ERC-721 tokens so in theory should be available to buy and sell on token trading sites like opensea as of launch date.
Heroes seem to be a requirement to play Crypto Saga, so i'd highly recommend getting your hands on a couple during pre-launch for a potentially reduced price.
