Powers that are overpowered and un-Warriors-like. Such as:

-Controlling the sun, moon or time
-Being able to break bones with one scratch
-Bring back cats from the dead, with no help from StarClan (leaders' lives don't count)
-Driving a monster
-Shapeshifting, perhaps illusions are fine but actually morphing is a no
-Killing a cat by just looking at them
-Bing able to fly like a bird

There are more, but I don't want to list them.
Also, having powers that have no consequences. Give a reason why these powers are something one must live with and not abuse.

I swear. This is turning into a 'How To' book slowly.

* Honestly, this is so far removed from warrior cats to where I don't really care all that much. At this point, just read an article or watch a video about how to write super strong powers. I just have to say this: if your MC has powers that can badically solve all physical problems, make the conflicts emotional and social. Have the main probelm be something they can't solve via monster-driving, time dilation, super killing, whatever. This is super basic, but if you want fun powers and an engaging story, it can't all be physical threats.
