Sailor Megtune
Sailor Megtune is Megan Schroeder's Sailor Soldier alter-ego in the Sonichu comic series. The character is blatantly plagiarized from Sailor Moon, a favourite show of Megan's.
In the comic
Sailor Megtune first appears in the fifth issue of Sonichu, along with Megagi La Skunk, who is apparently a sidekick of sorts.
Sailor Megtune is secretly in love with Chris, proof the comic is not based on real life. Chris very obviously reciprocates her feelings, but neither of them can act on those feelings due to "past events" or some shit.
Powers
Sailor Megtune has a guitar in which she is able to perform the attack, "Megtune Rockin' Hurricane". It's mostly used as a means of deflecting or canceling out enemy attacks, and is not shown to have any offensive capabilities.
