The best gift to get a more nerdy person is you guessed it something nerdy. This list is in no order as these items should be bought depending on what they like. If they like DC more or Marvel more you should cater towards those sides, or if they like anime more get them the anime inspired gifts.
If the your friend or partner loves collecting comic books then you’ll want to get them some. A 25 count of comic will put a smile on their face.
The hit animated show Invincible made a lot of people around the world new fans of the series. The comics and show are similar, but there are some differences that they’ll want to see for themselves. Gift them the first volume of the comics.
A basic necessity that a hardcore Marvel fan should have. It has data on almost all Marvel characters and teaches you things you probably didn’t know. Also could learn some stuff if you aren’t a Marvel fan.
If they like action figures or collectables and they like Marvel then getting them a Funko Pop of the most popular Marvel character will bring joy to their eyes.
One of the most popular Marvel weapons that every Marvel fan would love to have is this Infinity Gauntlet prop that has moving fingers and removable stones too.
On the other end of the spectrum we have the DC Encyclopedia for the DC fans. It has info on over 1000 characters, so they will be reading this for a while.
If your friend or partner is a DC fan and likes collectables then most likely they will appreciate the legendary Batman Funko Pop in his first appearance.
Every DC fan knows about Green Lantern and their rings. This set comes with the full emotional spectrum set of rings. It also comes in a nice box to hold them all. Also kinda fansionable.
Every anime fan know Naruto. And almost every anime fan loves Naruto(Some exceptions). So the first volume of the original Naruto would be an amazing gift for almost anyone.
With Demon Slayer being one of the most popular series out most people who watch anime love it. It has loads of items in it so they can have multiple uses for this.
The classic Death Note. An anime that everyone loves and has high on their list. The manga in my opinion is even better, so gifting them the entire set to read will be a solid choice.
