The comic book franchise is hoping to appeal to the so-called 'snowflake' generation by introducing two new characters – a pair of psychicpowered twins who are 'hyper aware of modern culture'. 

Snowflake, with cropped blue hair and matching leotard, is non-binary – meaning an individual who does not identify as either male or female – and can make snowflake-shaped blades for throwing. 

And twin Safespace – a term used to describe an environment free of bias, conflict or criticism – can create pink force-fields for defence against any unkind enemies. 

The twins, who will be introduced as part of a series called New Warriors, see their powers as 'a postironic meditation on using violence to combat bullying,' according to cocreator Daniel Kibblesmith. 

But the heroes have not been entirely well-received, with some claiming the characters' names make a mockery of the LGBT+ community and others branding the release a cynical publicity stunt.
