Battle for the Pride Lands
The Strange Cobra's only appearance in the episode is during a flashback in the musical number "When I Led the Guard".

When Scar was alive during his position as the Fiercest of the Lion Guard, he met the strange lion who wanted Scar to have more power than Mufasa upon seeing Pride Rock from a distance. The strange lion then leads Scar to his friend a venomous cobra which struck Scar on his left eye with his venomous bite, giving him his scar. Upon receiving his namesake, the lion then told Scar that the only way to purify the venom is to do his task but an out-of-control Scar uses the Roar against the two, destroying both the lion and the cobra. Afterwards, both the lion and the cobra are destroyed after Scar blasts them into the Outlands' volcano.

Strange Lion
This snake worked in collaboration with the strange lion, which is likely that he and the lion are friends. However, the snake gave Scar his namesake because the strange lion gave him a negative influence going near the cobra.
