There’s a definite seasonal flavour to Buzz’s round-up of interesting, weird and cool pics and videos this week. 

••• Guardians Of The Galaxy director James Gunn Instagrammed this fantastic Groot Chtistmas tree, created by WolfenM. You can see loads more on his Flickr.

••• Comic characters rarely age. Mr Fantastic actually looks like he’s grown younger over the years, though he may just be dyeing his hair these days. But what if they did age? That’s exactly what artist Eddie Liu has been pondering with these great portraits. Though quite why all his male DC characters have aged into distinguished-looking senior citizens while Wonder Woman has become Dot from EastEnders remains a mystery…

••• We thought Doctor Who had finished last Saturday, but there was a surprise extra episode on BBC One this Saturday night. It was very short and the Doctor had regenerated again into The Wanted’s Jay McGuinness but at least we know who’s playing the new companion now – Strictly Come Dancing’s Aliona Vilani.

••• Comic Book Resources has an occasional feature called “Shelf Porn” (we would explain the concept but the pictures speak for themselves) and the most recent entry was an absolute doozy. Sherry Konkus is a harpist and Punisher fan from Michigan, and she’s combined her two interests into a wonderfully bizarre display at her home. We just love the idea of Frank Castle sitting on a giant ball of wool…

••• A bunch of Star Wars: The Force Awakens stars took part in a Twitter Q&A to promote the film earlier this week. Nobody expected this would lead to a duet from Daisy Ridley and Oscar Isaac, but they spontaneously burst into a version of perennial favourite “Baby, It’s Cold Outside”. Maybe they thought they were on Hoth.

.@sherrilynling asks to Oscar and Daisy: can the two of you do a duet sometime? #TwitterAwakens pic.twitter.com/z6WkI3dXIa — Star Wars (@starwars) December 5, 2015

••• So who’s the fastest man alive? The Flash or Quicksilver? Marvel fans may not like the answer…

••• BOOM! Studios is launching its new Mighty Morphin’ Power Ranger series in January with a #0 issue. IGN this week revealed that every issue will have a Zord variant cover, starting with the Tyrannosaurus Zord. We know which set we’ll be collecting if they’re all as mighty as this.

••• This image is actually a couple of years old now, but we love the idea of TMNT Christmas tree baubles so much they may become the Wizard Of Oz of Guardians Of The Gallery, putting in an appearance every year. You can find out how to make them here…

••• After weeks of Star Wars-dominated Guardians Of The Gallery articles (is there a film coming out or something?) but this week there’s only one. A pair Hellcat muscle cars were pimped in the black-and-white uniform of a First Order Stormtrooper while a Viper ACR was repainted with a Kylo Ren-themed in a joint Star Wars/Fiat Chrysler publicity stunt. They toured the streets of LA over the weekend Fiat Chrysler encouraged Star Wars fans to post photos of themselves with the landspeeders… cars.

••• These are a late addition this week, added after we first went live with the feature, but they were too good to wait until next week to show you. Digital artist Allan Johnson shared a portfolio of his digital makeover of US dollars at  Moviepilot [via ComicBook.com], replacing the faces of the US political luminaries with comic and movie characters.
