Lets see... what is there to say about Elec Man's stage? It is decently long due to all the ladder climbing you need to do, it has a ton of annoying traps in it, and it has disappearing blocks. The electric traps are not so bad, but the floor spines do get very annoying rather quickly. You just never see them positioned in such ways in future games in the series... These days shooting them is completely unneeded. The reason this stage drags on, as mentioned, is the ladders... far too many ladders... Mega Man climbs incredibly slowly in the first couple of games, so yeah, this gets annoying very quickly. I do not like this stage very much, but at least it is not very difficult.
Elec Man himself can be easily dealt with with either the Rolling Cutter or the buster... in his regular room, at least. The rematch with him is another story altogether. The Rolling Cutter is simple since it kills him off in a mere three hits. With the buster... Roahm has a video up displaying how to deal with him using that... If your timing is good you can embarrass Elec Man almost as badly as Cut Man, hehe~ The major thing of note is Elec Man gives you the second best weapon in this game, Thunder Beam... Unless you use the pause trick for whatever reason, then I suppose one would consider it their favourite... *fist shake*.
Along the way the Super Arm also lets one get the Magnet Beam. This lets you create platforms in mid-air that you can walk along. This makes certain parts of the game dramatically easier, and yes I will be demonstrating this in full, hehe.
Enjoy!~
