[vechter]

do you have any fics where dick kicks ass? ive been reading a lot of relationship fics lately and i just wanna see him do some cool stuff! or any comics <33

hmm, all the fics i've read are older ones tbh because going into the dick grayson tag on ao3 is a true test of my patience and mental health now. but here's a couple of my favs:

greatest of ease by ijustwanttodestroy: multi-chapter outsider pov and it's just stellar. it was one of the first few dc fics i read so it will always have a special place in my heart.

strong enough to carry him by one_step_closer_to_death: dick and jason centric one shot. all the angst.

big d stands for big (demon)or by danishsweethearts: multi-chapter and still updating but this one is great. dick grayson as a part time exorcist. great voice for dick.

the primacy of personal conscience by birdsofthesoul: also one of the first few dc fics i read! multi-chapter, multi-pov, set in the modern comics era which is rare. genuinely fantastic writing and grappling with the morality and ethics of vigilantism. kinda iffy about some aspects of it but i adore this one.

as for comics:

nightwing (1996) #140-153: tomasi's entire run is just great. competent and complex dick grayson, when will you come back from war?

the brave and the bold (2007) #14-15: short story also featuring hawkman, deadman and green arrow, excellent stuff

let them live!: unpublished tales from the dc vault (2021) #2: one shot with a manipulative, earnest and hyper-skilled dick grayson

teen titans (1996) #12-16: this one also features garth, lilith, roy and wally. it has team-leader!dick & rlly shows how much everyone looks to him for directions + how well he can rise to that

justice league of america (2006) #41-60: this one is part of his batman era and it has donna! rlly highlights what a skilled tactician he is + how deceptive he can be

batman/nightwing: bloodborne (2002): i know i talk about this one a lot but it's just so good. dick grayson, you will never recover from that kind of devotion.

jla (1997) #68-75: obsidian age my beloved <3 dick leads a kinda B-team justice league to save the main one and he's great while doing it

batman and robin (2009) #20-22: okay, i know this is primarily a morrison run but the issues tomasi wrote for this are actually pretty solid

detective comics (1937) #871-881: this is snyder's black mirror arc and it has a healthy mixture of dick!bats kicking ass + some really great humour and dialogue. but also there's james gordon jr so rlly goes to show you can't have it all sigh

nightwing (1996) #35-37: part of NML where dick takes back blackgate for bruce. i've said this before but truly, no one shines more than dick grayson in a room full of people who want to kill him

just realizing a lot of the NML and dick!bats eras have some solid storylines if you're looking for a hyper-competent dick grayson. sadly, a lot of dixon's writing blurs together for me so i don't think i can give you individual issues.

hope this list helps, anon!

Click "keep reading" to see the answer! ↓

[ID: Comic panel of seven characters in various poses against different backgrounds. Text reads as follows.

"They came from everywhere, and in all forms and disguises. From the mysterious faceless crimefighter known as The Queston to the supernatural wizard called Prince Ra-Man.

"At times, the way fate creates its heroes appears almost capricious. Scientist Bruce Gordon appeared normal, but the rays of a total eclipse would change the young scientist into the evil Eclipso.

"Boston Brand suffered the most capricious of all fates when he was killed by a cadre of assassins only to be resurrected as Deadman.

"Aboard the Monitor's satellite I met hundreds of Earth's most courageous souls. People like Buddy Baker, the ANimal Man; Jack Ryder, the fearson Creeper; Johnny Mann, The Son of Vulcan; literally hundreds of brave men and women who risked their lives for the lives of others." /END]

Congratulations to @finndiseicla, @pluckyredhead and @kideternity  for being the first to guess correctly! 🎉

Each of you actually several right, and even though it was supposed to be one point per person, I'm giving two points each since you were the three that participated!

[deadguydeathmatch]

Welcome to the Dead Guy Death Match Elimination Round!

Due to the broad nature of death as a concept, most of the submitted characters only received a few votes each causing a massive tie. I figured the fairest way to sort out this issue would be to hold an elimination round to let you guys vote on who you want to make it into the bracket.

There will be two elimination rounds the first of which will start on Monday the 3rd of April at 3pm BST and the second will start on Saturday the 8th of April at 3pm BST.

Elimination Round 1 will feature polls of 5 or 6 unrelated characters (all of the matchups were generated randomly) for you to vote on. The lowest voted character will be eliminated and all of the remaining options will progress to the bracket.

Elimination Round 2 will feature polls of differing numbers of characters from the same or similar media and only the highest ranked character among them will progress to the bracket, all of the others will be eliminated.

Both sets of polls will last 24 hours.

I've tried my best to only include official images for all of the characters on the polls but I'm not familiar with every series listed so, when the polls go up, if you notice I've used a fanart or cosplay image without permission or credit please let me know and I'll add credit and correct it for any future appearances of that character.

The matchups are listed under the read more and hyperlinked to the polls

I apologise if I’ve accidentally spelled something wrong or used a wrong name for something, I’m not familiar with every series listed.

There will be spoilers for many series ahead.

❝ Being your friend should come with a warning label. ❞ gordon to benrey

You purse your lips at the words , gun still tightly in your hand as you had it pointed directly at the scientist , your gaze as steely as ever as you finally made the notion to lower the pistol from it's position now that the hazard that was a headcrab had been dealt with - though Gordon didn't seem too pleased with the quick thinking you opted for ( shooting the headcrab mid lunge , not even thinking about the possibility of shooting Gordon in the process )

" huh... ? whach'a say ? sorry man.. I don't listen to noobs who almost die to the easiest enemy in the game el - oh - el "

raising your free hand to pick at your teeth lazily , moving to push pass the physicists - continuing your tangent as you peer over @wouldhope .

" you.. you're pretty shit at the whole.. staying alive - Gordon deadman because of your c- clumsy little self - think getting this far you'd actually i d'nno - actually learn how to fuckin.. be good at killin ' next time benny boy here won't help since you gotta put a warning label on me f- for savin your ass ... jus' mad im a better gunner .. pew pew all those COD hours maxed out my stats in aiming an' QTEs .. "

[lewalrus]

Omg, there's a new interview with GDT about Pinocchio and they show a photo of him as a teenager and he looks so CUTE, with these giant nerdy glasses, like just the image of teenaged Deadman studying to be a doctor and wearing the same giant glasses and a white coat and meeting Sam at some BRIDGES party where his reaserch team came over to establish a reaserch project between the two groups... This idea is shaping up in my head 🥺 /🐈‍⬛

My friend, I would do anything to see this photo! I've seen one photo of young GDT on twitter one time and... damn he is really cute.

Friend! Can I suggest something for this AU? You probably already have an established idea for it, so you can just consider this as me rambling an idea.

I remember you said on your latest deadsam oneshot (by the way, I finally left my comment there and I had some problems because the comment was just too long for AO3 osjaosjaosja) that Sam had a crush on Gordon Freeman and that's how he started to think that he may be interested on guys too. Can you imagine they meeting at this "party conference" for the first time, young Sam and Deadman, Sam had some drinks already because everything is too boring and Bridget had basically forced him to be there and then he meet Deadman and thinks that his looks kind of resemble Gordon Freeman, especially his glasses, and, in a drunk state, straight up flirts with him the whole party, poor Deadman is losing his mind because the hot president son is flerting with him and he has no idea what to do.

This is the penultimate chapter of this story. Richie and Tori are in shock upon learning a face from the past, who has joined Cult X before the IUA takes the cult members into custody and Cassandra informs the couple of a prophecy regarding Duncan MacLeod; Duncan takes Clay's head after dueling him; Blue Bird aka Harper Row debuts in Earth N while helping Connor, the Defenders and the Bat Family; Methos joins the battle with the Justice League Dark fighting Destiny, including Mandrake, Lothar and Amy.

I just want to cry because the world hasn't been kind to me.

read it on AO3 at https://ift.tt/tMF0S4u by SpookyWing Dick Grayson died during Injustice. And instead of Boston, Rama Kushan named him the new Deadman. Dick Grayson continued to work hard after his death. He restored balance to the universe. He saw thousands of universes, worlds, destroyed. He saw universes reborn. And then Dick Grayson became a god. With Rama's help, he decided to go back thousands of years. To his original world! He just wants to see his family again and create a world that will make them happy. Well... Sometimes plans don't go as planned.
