Okay, so this boss has changed quite a bit since the old BaseROM. I'll list what's new and changed:
-It now has an official name: King Jelectro
-The boss fight will now give you a Torpedo so it's easier to dodge his attacks.
-He will flash depending on what attack he will do. He'll flash red when charging, and yellow when charing electricity.
-Additionally, his speed is lowered a bit so his charge attack is not incredibly hard to avoid.
-The new design below was drawn by Dr. Tapeworm. I drew the crown.
The boss fight is same as it was before outside of that, meaning this boss is complete, and needs no further revisions.
I have nothing else to say now. Huh...
