From left to right, we have Sally, Vector, Shadow Android, Whisper, my take on Sister Sonic, Scourge, Metal Knuckles, and (although not pictured since I forgot) Mephiles.
For Scourge, MK, Mail (Sister Sonic), Shadow Android, and Mephiles, I used the WM Blocks versions of Sonic, Shadow, and Knuckles as bases. The Metal Knuckles, Scourge, and Mephiles minifigures were actually purchased at a convention I went to with my parents during the pandemic. As for Mail and Shadow Android, they came with some other Sonic minifigures that I decided to get for Christmas, and instead of discarding the Shadow and Sonic duplicates, I simply repainted them.
Now, before I get to the rest, I want to show you all something cursed.
This is what the face of my custom Sally looks like. TL;DR, I didn't know I had a white acrylic marker (which is what I used for most of these), so I simply painted the eyes as is. However, I do plan to replace this by drawing the face on paper, cutting it out, and then gluing it onto the cursed face. A similar method was used to make Whisper's face, actually. But, back to Sally, I got the inspiration to do this from Wakeangel2001 when he made a LEGO Sally custom. Originally, I was going to make it the Rebooted version of her, but the marker didn't stick well, so instead, I made her an amalgamation of sorts: the pink and black color scheme comes from her appearance in the SatAM pilot, the long hair comes from Penders Era Sally, and the clothes come from the reboot.
Now, I already talked about how Whisper's face was done, so I'd like to take this moment to talk about her Wispon. I used a Star Wars blaster and stuck a black lightsaber hilt onto it, AND THEN, I stuck a clear 1x1 stud piece onto the hilt.
Vector got the least amount of changes; I used the head of Craeger from Chima and stuck it on a Sea Monster body, and then, I gave it black legs.
Here's actually some of them from the back.
Now, there are two characters I want to make but either I'm too nervous right now or I don't know if I have the right pieces. First is Honey the Cat with WM Amy as the base. The other one is a Surge custom, but I don't know if I have a plain green head that I can use in my inventory, and I do not know what hairpiece to use; I'm thinking of either using a ponytail piece or a hair down piece and coloring them green, but I don't know yet, maybe I'll let you guys decide.
There is one other thing I want to do, but I don't know if it makes sense, and that is to paint a scar on my official LEGO Amy's back. Basically, it's my headcanon that Amy actually lost the quill on her back in a battle or something, and now she has a scar on her back where that quill used to be. It's basically just my dumb answer to what happened to the quill, although it doesn't really make sense.
In summary, this is a ton of fun and I hope to do more in the future. Feel free to let me know what you think of these (or don't, I don't really care).
