- Jawhead was inspired by "Baby Head" known as Hover from Captain Commando
- Jawhead , Alpha, Saber, Angela and Johnson are only the heroes are mechanicals.
- Of all the mechanical heroes in the game, only Jawhead and Angela are fully mechanical.
- Jawhead is the only hero to have 2 voice actors: one for Ellie and one for Jawhead.
- Jawhead is one of the only heroes who has a rider (Irithel is the only other one). Unlike Irithel, Ellie prefers to watch over Jawhead's body rather than help him.
- While still in development Jawhead's first given name and hero title was Mecha Warrior, Prototype One.
- Was then changed to Jawhead but Ellie's name was Alice though.
- So it was then changed into Ellie to reduce the confusing of the two Alice.
