I would just use alpha transparency on it if possible with the game engine.

< really crappy example about alpha channel transparency

What leroy said... Additionally, you can improve the effect by a flashing animation.
(Experiment with the flashing speed)

Well in terms of it being an individual sprite even before its animated. I want it to glow. I was told to get rid of the white background and a few other things

Indeed the white background does not help. If you have a white light on a white background it will not look like it glows much. All a matter of relative brightness/contrast.
There are no ugly colours, only ugly combinations of colours.

Keep in mind that the "plasma blade" is not an opaque object, neither green with a white highlight in the middle, or white with a green outline, but a volume of transparent gas that glows green:
  • It is transparent all the way to the center, but of course more transparent near the edges where the plasma has less thickness. The right kind of compositing is addition, not normal alpha blending; light absorption, and thus opacity of the blade, should be negligible.
  • It cannot have outlines, unless you want the forcefield that contains the plasma to be somehow visible outside the blade proper. (Sparks etc. where the blade touches a target could act as temporary and partial outlines, making blade shape as clear as if outlined in a traditional way, particularly in the case of crossing plasma blades.)
  • There are two physically reasonable colour choices for plasma light: strictly monochromatic (specific excited states of specific substances), fading through all tones of green (or another hue), from very dark to very light, but not white; and black body radiation (any gas at very high temperatures), which for all practical purposes should be white, fading to grey.
  • Unless it's intended to be a toy weapon, the tip of the blade should be pointed rather than blunt and pillowshaded.

Hello  there. Well questseeker is right. If you know photoshop do this :
  • Insert your image, chose the weapon, and cut it into another layer
  • Make a new layer and work with the brush tool with low transparency or make an outer glow in Blending Options
