Notable Attacks/Techniques:

Overwrite: All Digimon can rewrite their data, so that they are able to react to various situations that were once problematic for it. This usually causes a gigantic increase in power, durability, speed and sometimes new skills and resistances to be gained. However, the more emotional the Digimon is, the more violent the overwrite becomes and thus can lead to negative effects. In AncientMermaidmon's case it has this ability to a ridiculous level allowing reactions to the emotions to be much faster and guarantee a much greater power increase than most Digimon can reach in a shorter period of time.
