The PolisPolice using MegatonFist on Serge.
MegatonFist (メガトンパンチ , Megaton panchi, lit. Megaton Punch?) is a White Enemy Tech used by the PolisPolice in Chrono Cross. This tech enables its user to literally punch a selected target, dealing fairly heavy damage in the process.
The PolisPolice will first retract his right arm and begins charging up power in said arm. He then dashes forward to deliver a punch to the selected target, causing said target to be lifted off his/her feet. An explosion of light energy will occur upon contact, and the target will sustain damage accordingly.
