Hero Mode

Hero mode is a visual mode typically drawn by Andrew in order to demonstrate the epicness that the character is currently going through. Thus far we have only seen the hero mode for John and for Rose; however, it is assumed that all four kids have a hero mode style of some sort.

Art Style
Typically, hero mode is drawn in a style that does not display the traditional black outline and instead looks like a completely custom drawing instead of a previously drawn and re-used sprite. It also seems that the proportions of hero mode seem to be just a tad bit different from normal sprite mode (as shown by Rose's multiple hero modes). All in all creating a more dramatic effect for the readers. Sometimes the mode has been known to shine the colors of the character with the alternating colors in the background.
