You can customize the badges using MediaWiki system messages.

MediaWiki:user-identity-box-group-sysop - Sysop (Administrator) Tag

MediaWiki:User-identity-box-group-founder - Founder Tag

MediaWiki:User-identity-box-group-chatmoderator - Chat Moderator Tag

MediaWiki:User-identity-box-group-blocked - Blocked Tag

MediaWiki:User-identity-box-group-staff - Staff Badge (Do not change.)

Look for these pages and you will be able to find it by going to http://randomexample.wikia.com/wiki/MediaWiki:example-message-blah-blah-blah. The text you add in those pages will control what the wording in those badges would be. If you replace "Admin" with "Sysop", the text in the tag will be "Sysop".
