If there is one thing I can say about sci fi, it has a lot of heart. Both the science fiction genre and fan culture have countless examples of caring for others, from family, to friends, to complete strangers. Fan passion goes hand-in-hand with compassion.
Take for example the story of R2-KT. On first glance one might dismiss it as a pink version of R2-D2 used as a marketing tool for girls. People who believe that would be so very wrong. R2-KT was an operational replica of R2-D2, trimmed with pink, made for one specific purpose: to make a dying girl happy.
I missed this story about Katie Johnson and her new cybernetic friend and guardian over a year ago when it first came out. I'm proud to pass this along to you now as a proud nerd, and as a person whose family has been forever changed by cancer.
THE STORY OF R2-KT CONTINUES. Katie Johnson's buddy has a fan page and makes appearances at conventions, children's hospitals, parades and more. R2-KT also has merchandise for sale benefiting charities like the Make A Wish Foundation and Toys For Tots. The page also seems to link together many Star Wars fans and clubs.
While the page still sports the disclaimer R2-KT is a fan-built project and not authorized by Lucasfilm as a recognized character... etc., it seems that the powers that be look upon R2-KT as a friend, considering that The Pink Imperial Droid with The Heart of Gold shows up at various official Star Wars functions, too. It has been featured at a Disney's Star Wars Day, and a Hasbro action figure was created to raise money for charity. It is now OFFICIALLY part of the Star Wars family, having appeared onscreen in The Force Awakens and the Clone Wars animated series.
May The Force be with you.
