Honestly, I say that Mecha Dragon is one of the worst bosses in the NES/Famicom Mega Man/Rock Man series.Mega Man 1 is a highly underrated game in my opinion, I think this game's Robot Masters had solid designs with lots of personality (the fact that they were made by Doctor Light also makes defeating them feel a little more personal), MM1 had not too easy and not too hard Robot Master stages (save for a highly difficult Wily Castle which I think is a good thing), an OST which is sadly small with short tracks but they were very catchy and suited their respective stages incredibly well. For example, Wily Stage 1 sounding very climactic and sinister. Not only could you use Robot Masters weapons effectively against Bosses but they went through the effort into making them all useful at least a couple times through the levels too, like freezing the fire in Fire Man Stage to help with the platforming, and freezing those bouncing enemies that deal huge damage to get past them, and there's the blocks you can pick up in Cut Man's Stage to wipe out those flying enemies, and you can head for Guts Man and Elec Man stages first to find ways to make lots of use of the Magnet Beam in the other four levels. It's a very replayable experience with weapons that are useful throughout each level. (Bomb Man's is a little weak but good against some of the slower enemies) Elec Man, Cut Man and Heat Man weapons are very fun to use. Graphically and Control-wise this game falls a little short compared to future titles but it still plays almost identically to your average Mega Man game and is a short and sweet experience. I also like the lack of E-Tanks, makes beating the game feel far more rewarding. Also the Yellow Devil is awesome, yes I said it. His Boss Music sums up the tensity of his fight well, he looks cool and it requires lots of concentration. I love Mega Man 2, but I find the Yellow Devil and Mega Man Clone boss fights in MM1 far better than the Robot Dragon, Tank Boss and that awful boss you use Crash Man's weapon for in MM2 Wily Castle personally.
