World of GeneX Mini - Shadow the Hedgehog

The Ultimate Life Form, created in collaboration with Professor Gerald Robotnik and the alien Black Doom. In GeneX, Shadow is introduced as a somewhat aimless wanderer in the wake of defeating the Black Arms. He develops a curiosity in the work of Bucky the Rat, and searches for information regarding the Experiments, and what Eggman wants with them. After the Kosmogon incident, he first aids Kosmo's escape from GUN, seeing a bit of himself in the morph. Then, he starts to work with GUN, working to contain threats like the Nocturnus Marauders and the Covenant of Despair. More recently, he struggled with Mephiles's attempts to recruit him during the Time Eater incident.

Shadow appeared in the majority of main GeneX storylines.
