Stan Lee Files for New Restraining Order Against Keya Morgan

5:24 PM PT -- Morgan tells us, "For over 10 years I have shown nothing but love, respect & kindness to Stan Lee, & his wife, a fact he has repeated countless times."

He continues, "This is a witchhunt by his daughter and her lawyer against me because she cannot stand the fact Stan likes me so much. I will 100% prove beyond a shadow of a doubt that the allegations against me are false. The truth will come out."

Stan Lee's legal battle with business partner Keya Morgan has intensified ... with ANOTHER restraining order.

Stan's legal team was in court Friday and requested the restraining order granted last month against Morgan to be dismissed. Stan's lawyers argued the first order -- submitted by attorney Tom Lallas on Stan's behalf -- should be voided as Lallas hadn't repped Stan for months.

The judge agreed -- tossed the order -- and Lee's legal team filed a new restraining order against Morgan.

In the new docs -- obtained by TMZ -- Stan's attorneys claim Morgan's mishandled more than $5 million of Stan's money and he's suffered severe physical and emotional injuries because of Morgan. The docs also claim Keya's tried to isolate Stan from his family and moved him to an undisclosed location last month.

Kirk Schenck, a legal rep for Lee tells us, “The Lee Family is conducting its own investigation, and working with the Los Angeles County District Attorney’s Office and the LAPD, in various investigations into Keya Morgan’s and others’ who may have taken advantage of the Lee Family. We will not comment further on the ongoing investigations for witness and evidentiary protection.”
