What game are you playing? That is always an important piece of information to include when asking for help. There are 1,000s of games on Roll20. Which character sheet are you using? There are hundreds of character sheets, and often more than one for any specific game - there are over 10 for D&D 5th Edition. That can affect the responses you get as well. I'll just assume you're playing D&D 5th Edition, and using either the D&D 5E by Roll20 (2014) or (2024) sheet, which means you just need to search for any Marketplace assets that fit your criteria, such as this: <a href="https://marketplace.roll20.net/browse/search?keywords=5e&category=Games:RPG%20Rulebooks|RPG%20Rulebooks:Bestiaries&page=2" rel="nofollow">https://marketplace.roll20.net/browse/search?keywords=5e&category=Games:RPG%20Rulebooks|RPG%20Rulebooks:Bestiaries&page=2</a> If you have a Pro or Elite subscription, then you can use the Transmogrifier to move monsters from one game to another. That's the easiest way. Otherwise you have to use the Character Vault or Characters page to move them individually one by one. You could also create a base game with all of the monsters and use that to make new games, and then all of your monsters would already be in the game, but that will also prevent you from using different Modules as the base of the game if needed.
