some of these will be in depth or their powers may already exist but shh-
Wu; some form of hindsight but only with tea
Kai; Burning Madness; he can only make fire whenever he gets extremely angry
Jay; Electricity but without the brain-dead drawback
Zane; ice
Nya; random mix of earphone jack and water- maybe like water sprouts from her ears
Lloyd; OfA or just green energy
Morro; Winds of Death; he can create a fog, and he plants silhouettes of the victims' family. When they get close enough, he possesses them
Chen; Stolen Staff; just a staff filled with other people's quirks, and the ability to steal the quirks of others
Nadakhan; Wishful Thinking; he can attach himself to whatever person he wants- and more than one person at a time and when their three wishes are up, they disappear from everyone's memory, except the people who the genie is attached to
