Akrid X is not easily bested, he is a difficult opponent. First things first in this battle VS are out of the question he will attack VS with pinpoint accuracy and incredible power. Stay on foot particularly in a nice high area. The VS rifle (if you can find it) is very usefull on it as its power is second to the pilebunker and the VS rocket launcher. being in places like a high area are little ways to stop Akrid X from constantly taking you health away and is a good vantage point to pound him. Now when you think you killed him he gets back up so be ready for round two. Akrid X is signifigantly weaker now but attacks do alot more damage and the Akrid is more aggresive. Watch out for his fire attacks they are very lethal if they hit and will kepp on making you use the harmonizer which puts you in place for another attack. Now use the same strategy as before and you should win.
