What are some examples of Deadpool comic covers that showcase a darker or more mature tone?

Several covers explore Deadpool's darker side. 'Deadpool' #32 (2014) by Ed McGuinness features a heavily bloodied and emotionally distraught Deadpool, reflecting a particularly violent storyline. Another example is 'Deadpool' #10 (2014) which depicts a grim and desperate Deadpool battling enemies in a bleak environment, suggesting a deeper level of psychological turmoil. These covers deviate from the usual comedic and action-oriented portrayals.
