I love that, that the Hawks would speak in an extreme nerdish internet way. The first time someone said something and Katar replied, "lol" while Shayera added, "lmao!" would be priceless.
I always thought it could be funny if alien heroes who learned English through some gadget suffered a slight misadjustment and just cursed all the time. A constant barrage of profanity from a serious, polite-acting Hawkman would strike me as hysterical.
