In roleplaying, this means that a player uses cheap tricks in order to win a battle. It is Known as OP for short and is used by many anime roleplayers who takes the role of Saint Seiya, Dragon Ball Z (hence the facts that saiyajin could destroy mountains and cities with a beam and saint seiya characters can't be hit twice by the same tech/spell/jutsu, for example) and most, hellsing and elfen lied based characters, and uses their 10th sense, vectors, and goes to a monster transformation to enter god mode in all around based battle RPGs.
Overpower acts include:
- Stopping attacks or actions without a logical reason, just because the character did it in the manga/anime;
- Constant use of cheap dodging (like utsusemi, the famous replacement by a wood log), force fields that last for absurd amounts of time, or impassable barriers that does not get weak, even if there are conditions that may decrease their effect;
- Some vampire players that are unaffected by the sun without having a logical explanation for it;
- Summonings of monsters that could overhelm an entire planet, like tiamat and cthulhu;
- Naruto characters who portrait Uchihas to use sharigan's tricks.
Damn, my character got pwned ridiculously. My enemy mantained a barrier for the entire battle and went overpower by summoning a giant dragon at the same time, the play was ridiculous.
