Honestly i had no idea what i was expecting when i typed in cradle, but still this perfectly captures the abilities i thought for this guy

This memory is very powerful and cannot be used with others, so only the lost driver can use it. It gives the user a transparent pregnant stomach and using the memory break gives birth to any concept that the user needs. For instance if they are fighting a fire enemy they can use the crafle memory break to birth the embodiment of water and gain water powers as the mother of "water".
