Idea of Fighter Icon
This looks like a space ship. It appears to be an up-side down triangle. There are two little squares connected to the bottom of the triangle. There's a small square on the top of the triangle, with its bottom missing. There's fire coming from the square.
This Fighter icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 6,100 icons, all in the same style and quality.
