The power to
suppress memories of others and/or oneself. Sub-power of Memory Manipulation. Not to be confused with Memory Erasure.
The user is able to suppress certain memories. For example, if one suffered from a truly traumatic experience, one could suppress it so as not to suffer through the pain and trauma.
Memory Restoration can restore suppressed memories.
Indomitable Will can slowly and naturally overcome suppression.
Memories cannot be suppressed forever, as the mind is an organism that would always recall the steps necessary for it to reach the present and thus "rewrite" itself to its original setting if one tries to change it.
