I am not going to lie, 2 or 3 years ago i had made a Self-MOC that was OP and that was Saido but now i have changed him and give my self a new self-MOC.
A Over Powered MOC is an over used idea that have feel like it was going on since the dawn of man, it mostly kills a good story, make there MOCs like gods and make them better then everyone elses MOCs plus it will make the character Boring. I have known some people that made there MOCs over powered, like
and Jex SelfMOC and
Now making a MOC that is OP for a short time is okay but if you make it so OP that no one can stop it, it is just stupid i mean really and some go with not giving him/her a weakness. Now if you do give him/her a weakness then that be interesting, than "MY MOC IS SO POWERFUL IT CAN DESTROY THE WORLD", i mean really that is just stupid.
I do like MOCs that are not Over Powered and just have a normal level of power or no power at all because it will help give a good story and a lot in making one, like with
Self-MOC Iax and My 2nd Self-MOC Manix Hount plus same with the Toa's in the main Bionicle Story.
Now to everyone i really recommend making a MOC that is not over powered.
