To ninja legends 2, came the metaverse update and you can get a badge.
To get the badge, you need to go to Planet Inferno and then in the back slightly right there is the wren's parkour and you need to complete it and if you complete it, then at the end of that parkour there is the Wren's chest and if you collect that chest, then you got the badge!
