It's not similar to evangellion at all. It's just /co/ autism made to annoy and confuse people, much like the "steven is doomguy and hazbin hotel girl's son" fad
The only similarities is Reggie and Asuka have long orange hair, lie in a hosptial bed, are hotheaded, and get bandaged up at one point. Also, reggie's escapism world is almost like when Shinji retreated into his own escapism fantasy to avoid growing up and responsibility.
But that's literally all. It's grasping at autism straws.
