Markus the Hedgehog is a male brown Hedgehog hailing from Ocean Point Village. He is Digger the Dog's closest friend and co-caretaker of Pixie. He was hurt and vanished in the attack on Ocean Point but was revealed to have survived his injuries and was hiding out in SlugTerra with Ace and Sara. He is based off of an Avatar created by Xbox user SynovialFlame75.
Markus is a young brown Hedgehog, and was noted by Monty the Dog to greatly resemble Rex Storm. He has deep brown fur, ice-blue eyes, and a white flame pattern. He wears a white camo neckerchief, orange and blue wristbands, and bright blue shoes. Similar to Stan the Wolf, he has a burn scar on his side, with Markus' being on his right side.
Markus is a laid-back, calm, observant fellow. He doesn't speak much, but when he does, he can be surprisingly insightful. He can be a bit hot-blooded sometimes, as he doesn't take kindly to people insulting Hedgehogs in general, as Shadow the Hedgehog (Sonic Boom) does to his face.
In The Legend of Fox the Brave:
The Phantom Storm:
The Struggle for Peace: Markus makes a brief appearance alongside Digger and Pixie when the three of them are kidnapped from their village by the Jackal Squad. While trying to lose the warriors, the leader takes Markus and threatens him, though this fails, and Fire Fox breaks his sword. Markus is rescued and returned to his village.
Digger and Markus are close friends, and even after many months apart, they maintain a healthy friendship. Markus often helps Digger look after Pixie.
Markus acts as a second brother to Pixie, and she calls him "Marky"(likely because she cannot fully speak yet). Markus often helps her brother look after her.
This Shadow views Markus as a failure to Hedgehogs, which greatly angers Markus. As a result, they don't like each other very much.
Markus is based off of a brown Hedgehog Avatar by Xbox user SynovialFlame75, whom series creator Burpy's Dream nicknamed Markus while trying to figure out the identity of Digger's childhood friend.
Markus is the first Hedgehog to appear in the series who is not apart of the official Sonic canon or tied to it in any way.
- Eli Junior, "E.J." the Hedgehog, while an original character, is related to Sonic the Hedgehog, and looks almost identical to his father.
Markus now has an arthritic back because of the several cracked spinal vertebrae he suffered before the Battle for Red Gate City.
