The wallet you used to mint or buy an Operator from the secondary market should be compatible with the airdrop. You will be able to connect to the NFT Gallery with MetaMask or WalletConnect.
For MetaMask users, the Gallery has been configured to automatically switch and populate network settings for Avalanche. If you have any issues viewing the comic or connecting your wallet to the Gallery, please open a ticket in Discord and let us know the wallet you are using.
