One word: mindfucked.
The two of them sound similar, has a girlfriend/wife, captains of the guards, and are proud warriors.
First time I heard Shining Armor, I was like OMG, it's Jaller! (I thought his voice may sound different) So yeah I draw Jaller as Toa Mahri and Shining Armor together. (I drew Shining Armor battle-damaged just to get a good look on him :3)
In the background, there's Chrysalis with Teridax's hand and also the changlings and Teridax's shadowy demon. Here, Jaller and Shining Armor are trying to fight for their loves. Sounded almost like a romantic story eh?
Such a silly title I used.
