Sentient flames are capable of inter-dimensional travel, moving from one plane of reality to another in search of either fuel, or knowledge to understand. A number of sentient flames became aware of the [[Outer Shield]] while travelling and spent some time examining it prior to finding a crack formed from within due to an inter-dimensional explosion from the [[Dimensional Fracture Bomb]]. While this allowed them within the shield, they found many hostile realities were seeping together, and also learned of [[The Crushing Fist]].
Friendly sentient flames also assisted in containing [[Green Freeze Flame]] which was being used to contain the spread of [[GLORWOC]].
